Full textAbstract:
Orange is one of the local fruits, which is a source of income for farmers in Narigunung 1 Village, Tiganderket District, Karo Regency. However, in recent years, many orange orchards have been attacked by the fruit fly pest of Bactrocera sp. (Diptera: Tephritidae), causing the oranges become rotten and fall. This resulted in losses for farmers; there are crop failures in some orchards, while the farmers had to pay off a large pesticide purchase. One of the effective ways to ward off the arrival of these fruit flies is by using ultrasonic waves. Based on a research, fruit flies will be disturbed if there are ultrasonic waves with a frequency of 25-30 KHz that work based on ambient temperatures above 18⁰C. In addition, to control the fruit fly population, this community service also used a modified steiner trap, employing methyl eugenol, which can stimulate male fruit flies to enter the trap. Both repellents and traps will be made at a height of where fruit flies are active around the orange tree. With this control system, the orange orchard will be free from fruit flies so that farmers will no longer experience losses; besides, ecological trapping of fruit flies will reduce the population of fruit flies around Narigunung 1 Village, Karo Regency.

Guava (Psidium guajava L.) is one of the most important commercial fruits grown in Punjab. Fruit flies (Bactrocera spp.) (Diptera: Tephritidae) are considered the key insect pest of guava causing yield losses and quality degradation during rainy season and thus decreasing fruit production. The present studies emphasis on ecofriendly management of fruitflies using the methyl eugenol pheromone traps (PAU traps) during 2017 and 2018. Fruit flies analysis by traps installation in guava orchard characterized high population of fruit flies (24.8–760.9) captured per trap per week (pooled mean of two years) in July to September. Population of fruit fly increased rapidly reaching its peak with weekly trap catches of 801.5 and 720.4 fruit flies/trap/week during the second week of August (32nd SMW) during 2017 and 2018 respectively, when the trees were at the maximum fruiting period. Maximum fruit infestation in control was observed in 34th and 35th SMW, i.e 67 and 81% as compared to 45 and 48% in treatment. The marketable fruits/ tree was 96 and 85 fruits/tree in treated plots as compared to 52 and 47 fruits/tree in untreated plots during 2017 and 2018 respectively. Mean fruit yield was 15.4 kg/tree and 12.6 kg/tree in treatment as compared to control with 8.8 kg/tree and 8.1 kg/tree during 2017 and 2019 respectively. There was significant increase in number of marketable fruits/tree and fruit yield. The results clearly depict that fruit fly traps offer one of the most effective method for the management of fruit flies especially in the rainy season.

Since its invasion in Senegal (West Africa) in 2004, Bactrocera dorsalis Hendel, the oriental fruit fly, has caused loss of production of mango and other commercial fruits. The use of neem products (oil, cake, and seed powder) and kaolin may be an alternative to synthetic insecticides for controlling adult flies and larval-pupal stages and may contribute to integrated pest management tactics. In the laboratory, neem oil-treated fruit had the same number of landings and time spent on treated fruit as the control but showed reduced pupal development. Females selected kaolin-treated fruits for landing less often, with reduced pupal development. Soil treatment with neem cake and neem seed powder reduced pupal survival. In the field, neem treatment had a greater number of infested fruits and greater pupal development than the control, but fewer flies emerged. Kaolin was not different from the control in percent of infested fruits or pupal development, but fewer flies emerged. Neem cake and neem seed powder were found to lose efficacy in the field.

Cayenne pepper is a horticulture plant (vegetable) where the fruit is used for various food purposes. The decrease of the chilly yields productivity caused by several factors including the use of varieties with low yields and the attack of Plant Pests (OPT). Pests that often attack chili plants are fruit flies. Petrogenol could be used to control this pest.The method used was a randomized block design with 7 treatments and 3 replications by comparing the dose of petrogenol.
The results showed that the D3 treatment showed the best parameters in the use of petrogenol doses in controlling fruit fly pests, in the parameters of healthy fruits, damaged fruit, insect catches, and damage intensity. The use of high doses of petrogenol can influence the trapping of fruit flies and as the control of fruit fly attacks

Full textAbstract:
Background: Fruit flies, especially of the Family Terphritidae, are economically important pests for the horticulture industry because many species cause serious mechanical damage to a number of crops of different plant families. Studies have shown that some species of fruit flies have the potential to contaminate fruits and vegetables with enteric bacterial pathogens. However, this has not been conclusively demonstrated. Methods: In this study, we investigated enteric bacteria carriage by Bactrocera dorsalis and its possible role in transmission of microbes into internal tissues of fruits. Fruit flies trapped using liquid protein bait, ripe mango fruits exposed to the fruit flies and controls, as well as mangoes obtained from farms with and without fly-control traps, were analyzed for microbes, such as total aerobic bacteria, total coliforms, yeast and molds, Escherichia coli and Salmonella/Shigella spp. using direct culture methods. Results and Discussion: The results revealed that a high percentage of these insects carries pathogenic bacteria. This finding shows that, like B. cacuminata and B. tryoni, B. dorsalis also carries pathogenic microbes. It was also observed that mangoes sampled from fly-control farms had significantly lower microbial loads and proportions of fruits contaminated compared to those from farms without fly-control. Additionally, all microbial counts of internal tissues were significantly higher for exposed mangoes compared to unexposed mangoes. These data indicate that B. dorsalis contaminates not only the external but also internal tissues of mangoes. Conclusion: These findings show that B. dorsalis carries pathogenic bacteria and plays a direct role in internalization of microbes in mangoes.

Full textAbstract:
Introductions In many areas, particularly in Asia, the oriental fruit fly Bactrocera dorsalis (Hendel) causes considerable fruit damage on various plants. The fruit fly causes significant economic losses every year due to reduced fruit quantity and quality as well as export restrictions. This study aimed to examine the potency of minerals in controlling the oriental fruit fly infestation in chili fruits. Methods Experiments were conducted under laboratory and semi-field conditions using randomized block design. Ten minerals (i.e. kaolin, talc, zinc oxide, bentonite, sulfur, dolomite, calcium oxide, calcium hydroxide, calcium carbonate, and zeolite) and an untreated control were tested under laboratory conditions. Twenty chili fruits at a green stage were soaked in each mineral suspension (2%, w/v), air-dried, and placed in a trial cage (23-L plastic container) containing 20 female oriental fruit flies. In a semi-field bioassay using a screen cage (100 cm × 70 cm × 120 cm), 20 female oriental fruit flies were exposed to a fruit-bearing chili plant sprayed with mineral suspension. Results Talc and calcium oxide significantly reduced the numbers of visiting fruit flies, oviposition holes, and eggs laid, as well as the percentage of infested chili fruits in a laboratory bioassay. Calcium hydroxide was substantially better than talc in controlling fruit fly infestation in a semi-field bioassay, although it was not significantly different from calcium oxide and calcium carbonate. Conclusion Overall, calcium oxide is a viable option for the long-term control of the oriental fruit fly on chili fruits. Calcium oxide could be utilized as the push component of a push-pull strategy to manage oriental fruit fly infestation in chili fruits because of its potential to inhibit the number of visiting fruit flies and oviposition.

“True fruit flies” belong to the family Tephritidae. Among them, the Mediterranean fruit fly (Medfly) Ceratitis capitata (Wiedemann) is the most economically important agricultural pest insect in the world. Anastrepha fraterculus (Wiedemann) is the South American fruit fly and represents a serious problem for countries of America. Both species share hosts fruits. Traditionally the control of fruit flies bases on the use of pesticides with chemical components. Due to their massive use to crops, pesticides are associated to environmental pollution and toxicity in mammals. An emerging technology is the use of nanomaterials with pesticidal activity or for the delivery of pesticides. The present paper reports: a) the synthesis of iron oxide (magnetite) nanoparticles and b) the effects of Fe3O4 nanoparticles during the development of the tephritid flies C. capitata and A. fraterculus. We sampled guava fruits to recover immature stages of fruit flies. Magnetite nanoparticles Fe3O4 were synthesized by co-precipitation of Fe (III) and Fe (II). We suspended doses of 100, 200 and 400 µg/ml of magnetite nanoparticles in water and we added the suspensions to larval medium. NPs are spherical with a medium diameter of 11 ± 2 nm and unimodal size distribution. During larval-pupal development, we checked out difficulties in the capacity to complete the natural biological cycle. Only 40% of larvae feeded in medium 400 μg / ml Fe3O4 NPs were able to continue their life cycle, in contrast to 92% of the control. Application of iron oxide (or magnetite) nanoparticles to larval food resulted in larvae toxicity expressed as dose-dependent lethality

Full textAbstract:
Fruit flies (Bactrocera spp.) are an important pest for horticultural crops, especially fruits and vegetables. One of the most effective and eco-friendly methods to control male and female fruit flies is by usingtraps that use Methyl Eugenol (ME) block plus fruit essence as an attractant. The purposes of this research were to acquire the most effective formulation of ME Block plus fruit essence to catch the most male and female fruit flies on the chili plantation and to detremine the increase in total of fruit flies caught. This research started from December 2017 to January 2018 at Cibeureum Village, Sukamantri District, Ciamis Regency, West Java Province. The research was conducted using a randomized block design consisting of 8 treatments and 3 repetitions. The treatments consisted of adding fruit essence to the ME block: 2 ml of ME on cotton; 2 ml of ME block; 2 ml of ME block + 4 ml of mango essence; 2 ml of ME block + 4 ml of orange essence; 2 ml of ME block + 4 ml of guava essence; 2 ml of ME block + 4 ml of star fruit essence; 2 ml of ME block + 4 ml of chili essence; Antilat (Organic pesticide) as a comparison. The results showed that ME block plus fruit essence has increased the total of male fruit flies caught, but it did not attract female fruit flies. The best combinations with the highest average of male fruit flies caught were ME block plus orange essence with 750.67/5 week, followed by ME block plus chili essence with 746.00/5 week

Full textAbstract:
Mango is one of the primary fruit export commodities in Indonesia. The productivity of mango can be increased by controlling the pest population, including fruit flies Bactrocera spp. Various efforts to control the population of fruit flies have been carried out, either by implementing traditional methods or by using synthetic pesticides. However, synthetic pesticides can cause pollution, and therefore we need to control the fruit flies’ population by using the most effective fruit fly trap mode. The study was conducted in the mango yield (monoculture) of Department of Agriculture in Majalengka. The traps in this study were modified Steiner traps with funnels, modified Steiner traps without funnels, bottle traps with funnels, bottle traps without funnels, and modified gypsy moth traps. Each trap was fed with 0.2 ml of Methyl eugenol dripped on a cotton roll and hung in the trap. The results showed that the number of fruit flies caught in each trap every week is significantly different. The highest number of fruit flies caught in each trap every week was achieved by bottle traps without funnels that caught 135 flies, while the lowest number of fruit flies caught was recorded by the gypsy moth traps with 16 flies. The transparent color of the bottles and a large number of holes effectively lured the fruit flies into the bottle traps without funnels.

The fruit flies of familyTephritidae are considered as serious pests of Mango in Sudan. They cause substantial damage to Mango in all Mango production areas. The application of various pesticides appeared to be ineffective. Therefore, this study was carried out to investigate the efficacy of Spinosad as new promising control measure to the fruit flies. This study was carried out at Shendi area, River Nile State during the period from April 2012 to August 2014, where Pheromone and food bait traps were used for detection and monitoring the fruit flies species in the study area. Spinosad (0.24g\L) was applied as a partial spraying pesticide. Results indicated that; the application of Spinosad highly decreased the fruit flies numbers. The average number of fruit flies collected in April was (947.22 and 1001.67) for the treated and untreated orchards respectively. The numbers of fruit flies in the treated orchards had decreased gradually during May, June, July and August, 904.7, 760.22, 609.6 and 452.7, respectively, but in untreated orchards for the same months had increased to 1003.67, 1103.67, 1336.67and 1468.67 respectively. However, the infestation level in mango fruits in the treated orchards was found to be 2% compared with 64% for untreated one.

A incidência de moscas-das-frutas é um fator de preocupação todos os anos nos perímetros irrigados do norte de Minas Gerais, principalmente em pomares de goiaba, acarretando aumentos nos custos e perdas na produção. Para se estabelecer um programa de controle de moscas-das-frutas, torna-se necessário o prévio conhecimento dos aspectos ecológicos dos tefritídeos e seus parasitóides. Portanto, o presente trabalho teve por objetivo conhecer a biodiversidade de moscas-das-frutas e de seus parasitóides em dois pomares comerciais de goiaba da região, os índices de infestação das moscas-das-frutas e a capacidade de Diachasmimorpha longicaudata parasitar moscas-das-frutas em goiaba no norte de Minas Gerais. Após três anos de coletas, em armadilhas tipo McPhail e em frutos, foram coletados 48.482 tefritídeos, sendo 45.012 exemplares de Anastrepha e 3.470 de Ceratitis capitata. Foram capturadas 18 espécies de Anastrepha, sendo que, A. turpiniae, A. manihoti, A. leptozona e A. barbiellinii estão sendo registradas pela primeira vez no norte de Minas Gerais. A. zenildae e A. fraterculus representaram mais de 90% de todas as moscas coletadas em armadilhas, sendo associadas às classes super de dominância, freqüência, abundância e constância. Somente C. capitata, A. zenildae, A. fraterculus, A. sororcula, A. obliqua e A. turpiniae emergiram das amostras de frutos. Destas, A. zenildae (58,8%), A. fraterculus (13,5%) e C. capitata (20,7%) corresponderam a 93% do total de fêmeas coletadas, sendo as responsáveis pelos altos níveis de infestação do pomar de Jaíba. Em Nova Porteirinha, somente três espécies de Anastrepha foram relacionadas aos frutos: A. fraterculus (50,3%), A. zenildae (37,8%) e A. obliqua (3,2%), além de C. capitata (8,6% do total de fêmeas). Nos dois pomares, as maiores infestações ocorreram de março a julho/2003, influenciadas principalmente pela disponibilidade de frutos maduros. Ocorreu interação de A. zenildae e A. fraterculus na exploração da goiaba no pomar de Nova Porteirinha. Foi discutida a relação entre percentagem de infestação e intensidade de infestação. O parasitismo natural de moscas-das-frutas em goiabas nos pomares comerciais do norte de Minas Gerais foi muito baixo. Dos 283 parasitóides obtidos, somente o braconídeo Doryctobracon areolatus e três espécimes do eucoilíneo Aganaspis pelleranoi foram registrados. Houve correlação positiva entre o número de adultos de opiíneos e os de Anastrepha spp. Foram recuperados 37 espécimes de D. longicaudata (24 em Jaíba e 13 em Nova Porteirinha), demonstrando que a espécie fechou o ciclo nas condições locais. Assim, D. longicaudata possui chances de se estabelecer na região, sem comprometer as relações tritróficas pré-existentes.The occurrence of fruit flies is a factor of concern every year in the irrigated areas in the north of Minas Gerais State, mainly in guava orchards, because they cause increases in the costs and losses in the production. To establish a fruit fly program control, it is necessary the previous knowledge of the ecological aspects of the tephritids and its parasitoids. Therefore, the objective of this work was to know the biodiversity of fruit flies and its parasitoids in two commercial guava orchards, the fruit flies infestation levels and the capacity of Diachasmimorpha longicaudata to parasitize fruit flies in guava in the north of Minas Gerais State. After three years of samplings, with McPhail type traps and on fruits, a total of 48,482 tephritids, was collected being 45,012 specimens of Anastrepha and 3,470 of Ceratitis capitata. Eighteen species of Anastrepha were captured; A. turpiniae, A. manihoti, A. leptozona and A. barbiellinii were registered for the first time in the north of Minas Gerais State. A. zenildae and A. fraterculus represented 90% of all fruit flies collected in traps and were placed in the category super of dominancy, frequency, abundance and constancy. Only C. capitata, A. zenildae, A. fraterculus, A. sororcula, A. obliqua and A. turpiniae emerged from fruits. From these, A. zenildae (58,8%), A. fraterculus (13,5%) and C. capitata (20,7%) corresponded to 93% of the total females collected, and they caused high infestation levels in the orchard located in Jaiba. In Nova Porteirinha, three species of Anastrepha were associated to A. fraterculus (50,3%), A. zenildae (37,8%) and A. obliqua (3,2%), besides C. capitata (8.6% of the total females). In the two orchards, the highest infestation occurred from March to July/2003, influenced mainly by the availability of mature fruits. Interaction of A. zenildae and A. fraterculus occurred in the exploration of guava in the orchard located in Nova Porteirinha. The relationship between infestation percentage and infestation intensity was discussed. The natural parasitism of fruit flies in commercial guava orchards in the north of Minas Gerais State was very low. Of the 283 parasitoids collected, the braconid Doryctobracon areolatus and three specimens of the eucoiline Aganaspis pelleranoi were recorded. There was a positive correlation between the number of adults of braconids and the number of Anastrepha spp. It was recovered 37 specimens of D. longicaudata (24 in Jaiba and 13 in Nova Porteirinha), which revealed that this species completed the cycle under local conditions. Therefore, there is a great success in establishment of D. longicaudata in this region without damaging the preexisting tritrophic relations.

No mundo todo, o manejo integrado de moscas-das-frutas é feito com associação do controle biológico aplicado e técnica do inseto estéril. Além da boa eficiência no campo, a associação dessas técnicas é também favorecida pelo fato de ambos os organismos, insetos estéreis e parasitoides, poderem ser produzidos massalmente na mesma fábrica com menor custo. Visando à produção massal do parasitoide de moscas-das-frutas Diachasmimorpha longicaudata e de insetos estéreis para atender a programas de manejo integrado de Ceratitis capitata e Anastrepha fraterculus, o presente trabalho foi desenvolvido no Centro de Energia Nuclear na Agricultura (CENA), da Universidade de São Paulo, entre os anos de 2006 a 2012. Durante esse período, metodologias de criação em laboratório foram implementadas e permitiram o desenvolvimento da tecnologia necessária para a produção desses insetos em grande escala no Brasil. Dados de 25 gerações do parasitoide produzido em grande escala em C. capitata tsl-Viena 8 e 51 gerações em A. fraterculus, bem como os efeitos e diferenças desses hospedeiros na qualidade do parasitoide foram analisados. É possível criar o parasitoide D. longicaudata em ambos os hospedeiros, C. capitata linhagem tsl-Viena 8 e A. fraterculus, entretanto essa linhagem de C. capitata não é indicada para produção massal do parasitoide, pois a emergência é muito baixa devido à debilidade do hospedeiro, possivelmente acarretada pelas manipulações genéticas que permitem a sexagem da mosca na fase embrionária. Caso essa seja a linhagem com melhor custo/ benefício disponível, recomenda-se o uso de larvas hospedeiras oriundas de ovos tratados termicamente para a produção do parasitoide. A criação em grande escala de A. fraterculus foi estabelecida com sucesso após o período de domesticação da espécie, obtendo-se larvas de boa qualidade com baixo custo, devido à dieta larval com baixa concentração de ágar e total uso de ingredientes nacionais nas dietas de adultos e larvas, por mais de 50 gerações. O uso de larvas irradiadas de A. fraterculus para a produção de D. longicaudata promove maior emergência do parasitoide, com maior quantidade e melhor qualidade de fêmeas que larvas de C. capitata.The integrated management of fruit flies is worldwide done with the association of augmentative biological control with parasitoids and the sterile insect technique. Beyond the efficiency in the field, the joint of both techniques is also favored by the easy production of organisms, both parasitoids and sterile insects, in the same facility with low costs. Aiming for the mass production of the fruit fly parasitoid Diachasmimorpha longicaudata and sterile insects to support integrated management programs for Ceratitis capitata and Anastrepha fraterculus, this work was developed at the Center of Nuclear Energy in Agriculture (CENA) of the University of São Paulo, between 2006 and 2012. Along this period, laboratory rearing methods were improved which allowed the development of the required technology for a large scale production of those insects in Brazil. Data of 25 generations of the parasitoid large scale production using C. capitata tsl-Vienna 8 strain and 51 generations using A. fraterculus as hosts are presented. Moreover, the effect and differences between hosts in parasitoid\'s quality were analyzed. The parasitoid D. longicaudata can be large scale produced using both C. capitata tsl- Vienna 8 or A. fraterculus as hosts, but this strain of C. capitata is not recommended for D. longicaudata mass production once the parasitoid emergency is very low due to the host weakness. If this strain is the best cost/benefit available, the use of host larvae originating from heat treated eggs might be considered to parasitoids production. The A. fraterculus large scale rearing was established successfully after the domestication period of the specie, producing a large amount of insects with excellent quality using local ingredients and little agar in the diet composition over 50 generations. A. fraterculus irradiated larvae as host for large scale producing D. longicaudata promotes greater parasitoid emergence with greater female biased sex ratio and better female quality than C.capitata larvae.

A partir de 148 amostras com parasitóides da família Braconidae, provenientes de levantamentos realizados com as moscas-das-frutas no Estado de São Paulo, foi feito estudo taxonômico, de distribuição e de associação com as moscas hospedeiras e fruteiras. Em 33 municípios, foram coletados 3.009 exemplares. A subfamília Opiinae foi a mais abundante com 96,2% dos exemplares. Apenas 3,8% dos parasitóides pertenciam à subfamília Alysiinae. Foram coletadas seis espécies de braconídeos: Doryctobracon areolatus (Szépligeti), Doryctobracon brasiliensis (Szépligeti), Utetes anastrephae (Viereck), Opius bellus (Wesmael) e Opius sp. (Wesmael), além do alisiíneo Asobara anastrephae (Muesebeck). A maior parte dos braconídeos (77,5%) pertencia a D. areolatus. Esta espécie foi associada ao maior número de espécies frutíferas (26), em 7 famílias, e ocorreu na maioria dos municípios amostrados (30). Foi associada a Anastrepha fraterculus (Wied.), A. obliqua (Macquart) e A. amita Zucchi, sendo obtida pela primeira vez de larvas de moscas em frutos de wampi, Clausena lansium (Lour) Skeels, e de canela-batalha, Cryptocarya aschersoniana Mez. Doryctobracon brasiliensis foi associada apenas A. fraterculus, sendo registrado pela primeira vez em ameixa-japonesa, Prunus salicina Lindl. Não foi possível associar as demais espécies de parasitóides às moscas-das-frutas. Opius sp. foi associada às larvas em canela-batalha (primeiro registro de planta associada). A percentagem de parasitismo de tefritídeos nos 33 municípios foi de 7,75%, variando de 0,02% a 40%. Foi elaborada uma chave de identificação para as espécies.This work presents the results of a survey of braconid fruit fly parasitoids from 33 localities in the State of São Paulo. In addition to the taxonomic studies, data of geographical distribution and association of braconid species to insect hosts and associated plants were also performed. A total of 3,009 specimens were colleted. The subfamily Opiinae was the most abundant with 96.2% of specimens colleted, and only 3.8% of the parasitoids belonged to the subfamily Alysiinae. Six species of braconids were collected: Doryctobracon areolatus (Szépligeti), Doryctobracon brasiliensis (Szépligeti), Utetes anastrephae (Viereck), Opius bellus (Wesmael) and Opius sp. (Wesmael), beyond the alisiíneo Asobara anastrephae (Muesebeck). Most of the braconids (77.5%) belonged to D. areolatus. This species was associated with the highest number of fruit tree species (26), in 7 families, and occurred in the majority of the cities sampled (30). It was associated to Anastrepha fraterculus (Wied.), A. obliqua (Macquart) and A. amita Zucchi, and it is recorded for the first time from fruit fly larvae in wampi, Clausena lansium (Lour) Skeels, and in "canela-batalha" fruits, Cryptocarya aschersoniana Mez. Doryctobracon brasiliensis was associated only to A. fraterculus, and it is recorded for the first time in fruit fly larvae in plum, Prunus salicina Lindl. It was not possible to associate the other parasitoid species to the fruit fly species. Opius sp. was associated with the fruit fly larvae in "canela-batalha" (first record of associate plant). The percentage of tephritid parasitism in the 33 cities was of 7.75%, varying from 0.02% to 40%. A key to identification for the braconid species was elaborated.

Full textAbstract:
This thesis has two focuses. The first problem facing the olive industry in the Eastern Cape is the growers’ perceptions of both what the industry will provide them and what a pest management program might entail. The second focus is the biology of olive pests in the Eastern Cape in terms of understanding their populations and their natural enemies on private farms, with future hopes of understanding how Integrated Pest Management strategies can be developed for this crop. Eastern Cape private farmers, small-scale farmers and workers from agricultural training institutions were interviewed regarding the history and cultivation of the local olive crop. Only one commercially viable olive grove was identified; other groves were small, experimental pilot ventures. The introduction of olives to small-scale farmers and agricultural training schools was generally a top-down initiative that led to a lack of sense of ownership and the trees being neglected. Other problems included poor human capital; poor financial capital; lack of adequate support; lack of knowledge transfer and stability; lack of communication and evaluation procedures of the project; miscommunication; and finally, olive pests. Apart from hesitancy to plant at a commercial scale, the main problem facing private farmers (Varnam Farm, Hewlands Farm and Springvale Farm) was pests. Therefore an investigation of pests from private farms was conducted ranging from collection of cultivated and wild olive fruit and flea beetle larvae for parasitism, trapping systems both for fruit flies and olive flea beetle adults. A survey of olive fruits yielded larval fruit flies of the families Tephritidae (Bactrocera oleae (Rossi), B. biguttula (Bezzi) and Ceratitis capitata (Wiedemann)) and Drosophilidae (Drosophila melanogaster (Meigen)) from wild olives (O. europaea cuspidata (Wall. ex G. Don) Cif.) but none from cultivated olives (O. e. europaea L.). Braconid wasps (Opiinae and Braconinae) were reared only from fruits containing B. oleae and B. biguttula. This suggests that B. oleae is not of economic significance in the Eastern Cape, perhaps because it is controlled to a significant level by natural enemies, but B. biguttula may be a potential economic pest. A survey of adult fruit flies using ChamP traps baited with ammonium bicarbonate and spiroketal capsules and Sensus trap baited with methyl eugenol and Questlure confirmed the relative importance of B. biguttula over B. oleae. ChamP traps were over 50 times better than Sensus traps for mass trapping of B. biguttula but both were ineffective for trapping B. oleae and C. capitata. Six indigenous flea beetles of the genus Argopistes Motschulsky (Chrysomelidae: Alticinae) were found, three described by Bryant in 1922 and 1944 and three new species. Their morphology was investigated by scanning electron microscopy and mutivariate morphometric analysis. The leaf-mining larvae are pests of wild and cultivated olives in South Africa and threaten the local olive industry. At Springvale Farm, A. oleae Bryant and A. sexvittatus Bryant preferred the upper parts of trees, near new leaves. Pseudophanomeris inopinatus (Blkb.) (Braconidae) was reared from 23 Argopistes larvae. The beetle larvae might not be controlled to a significant level by natural enemies because the rate of parasitism was low. The olive flea beetles showed no attraction to traps containing various volatile compounds as baits. The lace bug, Plerochila australis Distant (Tingidae), was sometimes a pest. It showed a preference for the underside of leaves on the lower parts of the trees. A moth, Palpita unionalis Hübner (Crambidae), was reared in very low numbers and without parasitoids. A twig-boring beetle larva, chalcidoid parasitoids and seed wasps of the families Eurytomidae, Ormyridae and Eupelmidae were also recorded.

Resumo: As moscas-das-frutas (Diptera: Tephritidae) são as principais pragas da fruticultura mundial. Na citricultura brasileira, elas são consideradas pragas de grande importância econômica e exigem cuidados quarentenários. No Brasil, os gêneros de tefritídeos mais importantes são Anastrepha e Ceratitis, cujas espécies que mais causam danos à fruticultura paulista são A. fraterculus, A. obliqua e C. capitata. Estratégias atuais de controle destas pragas agrícolas estão sendo estruturadas a partir do Manejo Integrado de Pragas (MIP), o qual é um sistema de decisão para uso de táticas de controle de pragas. Dentre as diferentes estratégias de manejo integrado de moscas-das-frutas, em plantações de laranja do Estado de São Paulo, o uso de iscas tóxicas merece grande destaque. Estudos recentes indicam que um agente eficiente para o controle biológico das moscas-das-frutas é o parasitóide exótico braconídeo Diachasmimorpha longicaudata. Em relação ao planejamento de um programa de controle de pragas, a modelagem matemática vem se mostrando de grande utilidade, pois permite reunir informações de diferentes áreas, simular diferentes cenários e analisar a eficácia de possíveis estratégias de manejo integrado de praga. O presente trabalho propõe um modelo matemático espacialmente explícito que descreve e simula as interações biológicas entre a mosca-do-mediterrâneo C. capitata e seu parasitóide braconídeo D. longicaudata, em plantações de laranja. Além disso, é apresentada uma nova forma de manejo integrado de C. capitata (com possíveis aplicações à Anastrepha spp.) baseada em aplicações conjuntas de iscas tóxicas com liberações inundativas de D. longicaudata, em plantações de laranja. Para tal manejo proposto, estratégias ótimas de liberações de parasitóides são analisadas através de simulações computacionais.Abstract: Fruit flies (Diptera: Tephritidae) are the main pests of the worldwide fruitculture. In Brazilian orchards of citrus, those flies are pests of great economic importance and they require quarantine measures. In Brazil, the most important tephritid genera are Anastrepha and Ceratitis, and the species that cause the greatest economic losses in the fruitculture of São Paulo State are A. fraterculus, A. obliqua and C. capitata. The current strategies for controlling these agricultural pests are being developed considering the Integrated Pest Management (IPM) techniques, which use the combined application of different methods of pest control. Among the different strategies of IPM applied to control fruit flies in citrus orchards on São Paulo State, the use of toxic baits has a great importance. Nevertheless, recent studies indicate that an efficient agent for the biological control of fruit flies is the exotic braconid parasitoid Diachasmimorpha longicaudata. A very useful tool for planning the program of pest control is the mathematical modeling application, which combines information from different areas and simulates different environmental backgrounds, besides of analyzing the effectiveness of possible strategies for the integrated pest management. The present study presents a spatially explicit mathematical model that describes and simulates the biological interactions between the Mediterranean fruit fly C. capitata and its braconid parasitoid D. longicaudata in citric orchards. Furthermore, we also propose a new type of integrated pest management strategy for C. capitata (with possible applications to Anastrepha spp) based on the combined use of toxic baits and inundating releases of D. longicaudata in citrus orchards. For such management, we present computer simulations used to analyze optimal strategies for parasitoid releasing.

Visando contribuir para o manejo de moscas-das-frutas em parreirais de uva, inicialmente determinou-se, neste estudo, a concentração limiar dos limonoides azadiractina e 3-tigloilazadiractol (AzaMax®) capaz de inibir completamente a oviposição de Ceratitis capitata em frutos de uva. Em seguida, foram averiguados os estímulos envolvidos na inibição da oviposição da praga pelos referidos limonoides. Posteriormente, avaliou-se a proteção do parreiral de uva pelos limonoides contra C. capitata no polo de produção de Petrolina/PE, Brasil. Finalmente, foi avaliada a atividade biológica residual dos limonoides sobre a praga em parreiral de uva no polo de produção de Petrolina. A concentração limiar para a completa inibição da oviposição de C. capitata se dá com 100 ppm de azadiractina (+ 28,5 ppm de 3-tigloilazadiractol) na superfície de frutos de uva. A inibição da oviposição é drástica a partir de 50 ppm de azadiractina (+ 14,3 ppm de 3-tigloilazadiractol) em situação de chance de escolha do hospedeiro. A seleção hospedeira de C. capitata não é afetada por concentração igual ou inferior a 7,5 ppm de azadiractina (+ 2,14 ppm de 3-tigloilazadiractol) na superfície de frutos de uva. A concentração limiar de 100 ppm de azadiractina (+ 28,5 ppm de 3-tigloilazadiractol) impede que o hospedeiro seja reconhecido pela praga em função dos estímulos que promovem a inquietação (irritação), locomoção e consequente dispersão da praga. Assim, os limonoides (AzaMax®) podem ser qualificados como repelentes com baixa capacidade de difusão. Os limonoides em alta concentração ocasionam mortalidade sobre C. capitata, porém não evitam que os cachos ou frutos de uva sejam injuriados e ou infestados por C. capitata numa condição de baixa população natural ou artificial em campo. As conclusões registradas corroboram a hipótese de que são necessárias mais investigações pormenorizadas para avaliação do efeito de limonoides do nim sobre C. capitata em campo. A perspectiva de controle comportamental de moscas-das-frutas utilizando limonoides do nim foi discutida, com especial referência para C. capitata em parreirais de uva.Aiming to contribute to the management of fruit flies in the vineyards, this research initially determined the concentration threshold of limonoids azadirachtin and 3-tigloylazadirachtol (AzaMax®) able to completely inhibit oviposition of Ceratitis capitata in grape fruits. Then the stimuli involved in the inhibition of oviposition of C. capitata by these limonoids were investigated. Subsequently, we evaluated the vineyard protection by limonoids against fruit flies in the production pole of Petrolina - PE, Brazil. Finally, we evaluated the residual biological activity of limonoids on C. capitata in vineyard in the production pole of Petrolina. The threshold concentration for complete inhibition of oviposition of C. capitata is 100 ppm of azadirachtin (+ 28.5 ppm of 3-tigloylazadirachtol) on the surface of grape fruits. The inhibition of oviposition is drastic from 50 ppm of azadirachtin (+ 14.3 ppm of 3-tigloylazadirachtol) with free choice of the host. The host selection by C. capitata is not affected by concentration equal to or less than 7.5 ppm of azadirachtin (2.14 ppm of 3-tigloylazadirachtol) on the fruits surface. The threshold concentration of 100 ppm of azadirachtin (+ 28.5 ppm of 3-tigloylazadirachtol) prevents the host to be recognized by C. capitata depending of the stimuli that promote caring (irritation), locomotion and consequent dispersion of insect. Thus, the limonoids (AzaMax®) can be qualified as repellents with low diffusion capacity. The limonoids in high concentration (AzaMax®) cause mortality of C. capitata, but do not prevent the injury and or infestation on grape clusters by C. capitata in a condition of low natural or artificial population in the field. The findings reported support the hypothesis that more detailed assessment for the effect of neem limonoids on C. capitata in field investigations are necessary. The perspective of behavioral control of fruit flies using neem limonoids was discussed, with special reference to C. capitata in vineyards.

Peach Prunus persica (L.) Batsch is an important cash crop cultivated in southern Brazil more specifically in the region of Encosta Superior do Nordeste belong to the state of Rio Grande do Sul . In that region, peach is cultivated in small areas by farmers that use family labour and have the diversification of activities as economic strategy. The potential for growing fresh peaches is enhanced by reaching local market in high quality fruit, and having premium prices for that. This study was carried out in two parts. The first one aimed to know the perception of peach organic growers facing the fruit fly Anastrepha fraterculus. The second part, three experiments were conducted in randomised blocks for testing the effect of homeophatic compounds to control A. fraterculus. The treatments consisted of nosodium of A. fraterculus and Staphysagria in two dilution levels, CH3 and CH6, combined by two application intervals , 5 and 10 days. A commercial Composto A , made with several herbs and largely used by organic farmers was evaluated in the third experiment. All experiments were conducted in organic orchard systems located in Antônio Prado, Rio Grande do Sul. Two experiments were conducted during the 2003-2004 crop cycle and another during the 2004-2005 crop cycle. The homeophatic compounds were prepared according to the Farmacopéia Homeopática Brasileira (1997). From the result we could see that farmers have a diversity of varieties of peach and production was mainly offered to local market. Anastrepha fraterculus was the only specie found into traps and fruits. The homeophatic compounds did not reduce significantly the A. fraterculus infestation compare to the proof. Fruit losses due to fly infestation varied from 40 to 98,3%. Nevertheless two treatments differed to the worst preparation treatment and can be used as an alternative treatment combined with other crop management measures. Although Composto A had the lowest infestation level (38%) it did not difered to the proof (63%). More studies would be necessary to recommend homeophatic compounds for protecting preaches from fruit fly. Besides bagging individual fruits, planting early maturation cultivars would an efficacy measure to control fruit fly although local monitoring is needed. In another hand, the preference for using Composto A by the organic farmers showed the fragility of the peach organic system studied
A cultura do pessegueiro Prunus persica (L.) Batsch, possui fundamental importância para a economia da Região da Serra Gaúcha geograficamente conhecida como encosta superior do nordeste do Rio Grande do Sul, onde é cultivado em minifúndios. O pessegueiro representa importante alternativa na diversificação da matriz produtiva, gerando renda em pequenas áreas e empregando mão-de-obra familiar. Neste trabalho, estudou-se a percepção dos agricultores frente à mosca-das-frutas sul americana Anastrepha fraterculus (Wied) (Diptera: Tephritidae) e a eficiência de preparados homeopáticos no manejo da mesma. Questionário semi-estruturado foi aplicado em 12 agricultores na região da Serra Gaúcha que adotam sistema de cultivo orgânico do pessegueiro. No estudo de preparados homeopáticos, três experimentos foram conduzidos também em sistema de cultivo orgânico com a variedade Chiripá, delineados em blocos ao acaso, sendo dois no ciclo de cultivo 2003/04 e um no ciclo 2004/05 no município de Antônio Prado, RS. Os tratamentos constituíram-se de nosódios de adultos de A. fraterculus e do composto homeopático Staphysagria na terceira e sexta diluição centesimal hahnemanniana, combinados a intervalos de aplicação de cinco ou 10 dias. O produto comercial Composto A, formulado a base de fermentados de plantas foi testado no ciclo de cultivo 2004/05. Os preparados homeopáticos foram obtidos conforme Farmácia Homeopática Brasileira (1997). Observou-se que os agricultores diversificam o cultivo do pessegueiro com uso de diferentes variedades, destinando sua produção aos mercados locais. Dados experimentais evidenciaram redução na infestação da mosca-das-frutas na primeira colheita com uso de..Staphysagria na Sexta diluição centesimal e Nosódio de Mosca-das-frutas também na Sexta diluição centesimal, respectivamente no primeiro e segundo experimento. Entretanto nenhuma das combinações testadas diferiu da testemunha sem intervenção. Perdas na produção de frutos variaram de 40 a 98,3%. Da mesma forma, o Composto A embora tenha apresentado a menor porcentagem de frutos infestados (38%) não diferiu da testemunha (63%). Pelo relato dos agricultores e pelos dados obtidos sobre a dinâmica populacional da mosca-das-frutas, observou-se que o cultivo de variedades precoces de pessegueiros aparece como medida mais eficaz para reduzir as perdas de frutas provocadas pela mosca-das-frutas sul americana, além do próprio ensacamento de frutos. Entretanto, pela praticidade apresentada os agricultores orgânicos, estes demonstraram preferência para uso do Composto A, o que revela a fragilidade das estratégias atualmente empregadas para o manejo desta praga na região da Serra Gaúcha

The generation of information about the potential of alternative tactics in the control of fruit flies has attracted a growing interest, both producing and researchers. This research aimed to evaluate the effects of guava cultivars and substances from plant metabolism on biological parameters of Anastrepha fraterculus (Wied., 1830) (Diptera: Tephritidae) and Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae). The study was conducted in the Laboratory of Plant Resistance, Department of Plant Protection, Faculty of Agricultural Sciences and Veterinary Medicine - UNESP. The guava fruits were obtained from Company Val fruits, located in “Vista Alegre do Alto” - SP. The fruit-flies and parasitoids were derived from rearing on artificial diet in the laboratory Radioentomologia - CENA. 6 bioassays were conducted: 1- Determining the maturity stage of guava fruits preferred for egg-laying of A. fraterculus, 2- No preference for egg-laying of A. fraterculus fruits of the guava cultivars, 3- Effect of natural products used in guava fruit on egg-laying of A. fraterculus, 4- Association of the effects of the fruits of guava cultivars and natural products on parasitism of D. longicaudata, 5- Antibiosis test of fruit varieties of guava and on A. fraterculus and 6- Effect of extrinsic resistance of cultivars of guava fruit on the parasitoid D. longicaudata.

Full textAbstract:
Apart from its traditional role in disease control, recent body of evidence has implicated a role of the immune system in regulating metabolic homeostasis. Owing to the importance of this “immune-metabolic alignment” in dictating a state of health or disease, a proper mechanistic understanding of this alignment is crucial in opening up for promising therapeutic approaches against a broad range of chronic, metabolic, and inflammatory disorders like obesity, diabetes, and inflammatory bowel syndrome. In this project, we addressed the role of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) innate immune pathway in regulating different metabolic parameters using the Drosophila melanogaster (DM) fruit fly model organism. Mutant JAK/STAT pathway flies with a systemic knockdown of either Domeless (Dome) [domeG0282], the receptor that activates JAK/STAT signaling, or the signal-transducer and activator of transcription protein at 92E (Stat92E) [stat92EEY10528], were used. The results of the study revealed that blocking JAK/STAT signaling alters the metabolic profile of mutant flies. Both domeG0282 and stat92EEY10528 mutants had an increase in body weight, lipid deprivation from their fat body (lipid storage organ in flies), irregular accumulation of lipid droplets in the gut, systemic elevation of glucose and triglyceride levels, and differential down-regulation in the relative gene expression of different peptide hormones (Tachykinin, Allatostatin C, and Diuretic hormone 31) known to regulate metabolic homeostasis in flies. Because the JAK/STAT pathway is evolutionary conserved between invertebrates and vertebrates, our potential findings in the fruit fly serves as a platform for further immune-metabolic translational studies in more complex mammalian systems including humans.

Full textAbstract:
The testing of an innovative amber-containing biotextile developed within the EUREKA project IFSITEX revealed the ability of biotextile material to protect test objects from UV-B radiation and extremely low-frequency electromagnetic fields (ELF-EMFs). One of two different testing methods is based on flow cytometry indicating changes in the relative fluorescence of immature plant gametes based on the determination of the sum of changes in approximately 20 various parameters of gametic cells affected in one nuclear stage by irradiation of cell suspension covered with biotextile fabrics containing amber particles or similar fabrics lacking amber particles with UV-B for 75 minutes. The second test called Drosophila melanogaster survivability test, specifically modified for biotextile testing, revealed differences in the percentage of successful development of D. melanogaster from larvae to imago stage after growing fruit flies in tubes covered with biotextile material containing amber particles as well as material free of amber particles. Tubes with D. melanogaster larvae were placed in a Helmholtz coil were continuously exposed to a sinusoidal 50 Hz magnetic field (MF) at a flux of 450 μT. Survivability results were compared to the success of the development of the control which was not affected by experimentally generated ELF-EMFs D. melanogaster. Samples of biotextile containing amber particles were found to retain UV-B and LF-EMF radiation better than fabric samples without amber particles.

Full textAbstract:
The Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), is a ubiquitous pest of fruit trees, causing significant economic damage both in the U.S. and in Israel. Control efforts in the future will rely heavily on the sterile insect technique (SIT). Success of such operations hinges on the competitive ability of released males. The mating system of the medfly is based on leks. These are aggregations of sexually signaling males that attract females (who then select and copulate a courting male). A major component of male competitiveness is their ability to join existing leks or establish leks that are attractive to wild females. Accordingly, we identified leks and the behaviors associated with them as critical for the success of SIT operations. The objectives of this proposal were to determine 1. what makes a good lek site, 2. what are the energetic costs of lekking, 3. how females choose leks, and finally 4. whether the copulatory success of sterile males may be manipulated by particular pre-release diets and judicious spatial dispersal. We established that males choose lek sites according to their spatial location and penological status, that they avoid predators, and within the lek tree choose the perch that affords a compromise between optimal signalling, micro-climatic conditions and predation risk (Kaspi & Yuval 1999 a&b; Field et al 2000; Kaspi & Yuval submitted). We were able to show that leks are exclusive, and that only males with adequate protein and carbohydrate reserves can participate (Yuval et al 1998; Kaspi et al 2000; Shelly et al 2000). We determined that females prefer leks formed by protein fed, sexually experienced males (Shelly 2000). Finally, we demonstrated that adding protein to the diet of sterile males significantly enhances their probability of participating in leks and copulating wild females (Kaspi & Yuval 2000).

Full textAbstract:
This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasions, in order to contain them. Prediction of dispersal patterns facilitates preemptive action, and estimates of the pests' abundance lead to quantification of medfly infestations and control efforts. Although olfactory attractants and traps exist for capturing male and mated female medflies, there are still no satisfactorily efficient means to attract and trap virgin and remating females (a significant and dangerous segment of the population). We proposed to explore the largely ignored mechanism of female attraction to male song that the flies use in courtship. The potential of such an approach is indicated by studies under this project. Our research involved the identification, isolation, and augmentation of the most attractive components of male medfly songs and the use of these components in the design and testing of traps incorporating acoustic lures. The project combined expertise in acoustic engineering and instrumentation, fruit fly behavior, and integrated pest management. The BARD support was provided for 1 year to enable proof-of-concept studies, aimed to determine: 1) whether mate-seeking female medflies are attracted to male songs; and 2) over what distance such attraction works. Male medfly calling song was recorded during courtship. Multiple acoustic components of male song were examined and tested for synergism with substrate vibrations produced by various surfaces, plates and loudspeakers, with natural and artificial sound playbacks. A speaker-funnel system was developed that focused the playback signal to reproduce as closely as possible the near-field spatial characteristics of the sounds produced by individual males. In initial studies, the system was tasted by observing the behavior of females while the speaker system played songs at various intensities. Through morning and early afternoon periods of peak sexual activity, virgin female medflies landed on a sheet of filter paper at the funnel outlet and stayed longer during broadcasting than during the silent part of the cycle. In later studies, females were captured on sticky paper at the funnel outlet. The mean capture rates were 67 and 44%, respectively, during sound emission and silent control periods. The findings confirmed that female trapping was improved if a male calling song was played. The second stage of the research focused on estimating the trapping range. Initial results indicated that the range possibly extended to 70 cm, but additional, verification tests remain to be conducted. Further studies are planned also to consider effects of combining acoustic and pheromonal cues.
