Повний текст джерелаField experiments with the green peach aphid on tobacco were conducted at Blackstone, Virginia in 1983 and 1984. The objectives were to: 1) confirm and identify source materials resistant to the green peach aphid; 2) study the inheritance of aphid resistance; 3) verify heritability of resistant genotypes through F2 and advanced generation testing and 4) investigate the nature of the resistance.
Results showed green peach aphid resistance in Tobacco Introductions 1462, 1118, 1112, 1024, breeding line 1-35 and cultivar NC 745. Inheritance studies showed that the resistance is a recessive trait controlled by three separate, non-linked loci; such that a homozygous recessive at any one locus will condition for the resistance reaction. Among the source materials, one locus conditioned the resistance shown by TI 1118, TI 1112 and breeding line I-35. A second independent locus conditioned the found in TI 1024 and a third independent locus conditioned the resistance observed in NC 745. Tobacco Introduction 1462 possessed alleles for resistance at both the second and third loci.
Small aphid cages were of questionable value for studying the resistance reaction. Higher leaf temperatures were noted for the caged leaf surfaces and may be responsible for the unreliable results.
Evaluation of F2, F3, F5, F5 populations developed from resistant x susceptible crosses indicated that aphid resistance is a heritable trait and is not closely linked to adverse agronomic quality characteristics.

Повний текст джерелаThe green peach aphid Myzus persicae is a globally significant crop pest, controlled mainly by chemical treatments. In recent years neonicotinoids and pyrethroids have been the main components of pest management strategies used by growers. However, recent monitoring programmes in Southern Europe have shown the widespread presence of resistant populations, posing a serious threat to the long-term efficacy of these insecticide classes. The present work aims to characterise the main biochemical and molecular mechanisms responsible for insecticide resistance in Italian populations of M. Persicae. The first part is focused on target-site resistance and consider the frequency and distribution of the main target-site mutations associated with neonicotinoid and pyrethroid resistance. The second part is related to metabolic resistance and analyses the involvement of detoxifying enzymes able to sequester or metabolise the insecticide molecules. Furthermore, the project aims to characterise possible interactions between those enzymes and synergistic compounds like the well-known piperonyl butoxide (PBO). Results obtained by this investigation will help to improve insecticide resistance management strategies, in order to avoid ineffective applications and maintain the long-term sustainability of chemical control against M. persicae.

Estudos vem comprovando os danos que os venenos químicos podem causar ao ambiente e especialmente ao homem, tornando sua utilização praticamente insustentável. Assim, vem ocorrendo um resgate do conhecimento tradicional. Por outro lado, a sociedade tem exigido produtos nutritivos, saudáveis e com um mínimo de dano ao ambiente. Nesse sentido, a macela (ou marcela) apresenta várias vantagens em relação ao uso de agrotóxicos, pois constitui uma forma alternativa de controle de insetos, pela redução de riscos à saúde e de custos, além de ser um produto saudável, sem efeitos colaterais e período de carência, sendo possível o consumo da planta tratada logo após a pulverização, algo impensável para os pesticidas químicos. O principal objetivo deste trabalho foi avaliar o efeito do chá de macela no controle do pulgão verde Myzus persicae (Sulzer, 1776) utilizando o cultivo hidropônico de hortaliças folhosas como modelo experimental. Paralelamente, foi testado também um sistema de criação de pulgão experimental para a obtenção de uma colônia estoque para realização de experimentos. Para realização dos testes foram utilizadas plantas de Rúcula, infestadas com colônias de pulgão verde, em vasos contendo substrato (70% vermiculita, 30% areia e 20% substrato comercial) acondicionados em bandejas plásticas forradas com lã sintética comercial, que servia como reservatório da Solução Hidropônica que era reposta a cada dois dias. Foram pulverizadas sobre as plantas três diferentes concentrações de chá de macela, 5, 10 e 20 gramas de inflorescências por litro de água, mais água destilada, que consistiu a testemunha. Foram realizadas duas contagens, uma 24 e outra 48 horas após a aplicação dos diferentes tratamentos, contando-se os pulgões encontrados em dez folhas escolhidas aleatóriamente em cada planta tratada. Foram observadas eficiências de controle de até 80,9% para a concentração de 5 g.L-1, 91,6% para a concentração de 10 g.L-1 e 85,3% para a concentração mais elevada de chá, 20 g.L-1. Verificou-se uma alta eficiência do chá de macela no controle de pulgão verde em cultivo protegido, demonstrando seu potencial como uma alternativa a utilização de agrotóxicos no controle desse inseto de grande importância agronômica e que causa danos a culturas em todo o mundo. O chá de macela foi efetivo em todas as concentrações testadas, quando comparadas com a testemunha, mas a maior eficiência foi verificada para a concentração de 10 gramas de inflorescências por litro de água. Quanto ao sistema de criação de pulgão desenvolvido, ele demonstrou-se muito eficiente e de fácil manutenção, provendo uma colônia estoque suficiente para a realização dos experimentos. Devido a verificação da alta eficiência do chá de macela no controle do pulgão verde, recomenda-se ampliar os estudos de extratos de diferentes plantas no controle de insetos de importância agrícola.

Повний текст джерелаThe search for alternatives to the use of pesticides in horticultural production has become a public health requirement. Thus, the introduction of Companion plants (CP) is an ecological method that can help reduce the use of chemical control against Myzus persicae, the green peach aphid. The interest of some of these CP lies in their ability to disturb the installation of the aphid on its host plant and/or to reduce its performance through the emission of volatile organic compounds (VOCs). However, a major obstacle to their use is that their effectiveness is limited to a limited scope and their olfactory production is sensitive to many biotic and abiotic variables. Identifying the most efficient plants, understanding their mode of action and seeking to optimize their effectiveness is therefore an appropriate approach to promote their use in horticulture. Olfactory environment analysis is a key to assessing and understanding CP-host plant -aphid interactions.In the laboratory, we selected with a Y-olfactometer two CP producing VOC mixtures with a marked repellent effect on M. persicae: basil (Ocimum basilicum) which acts directly on the insect, and french marigold (Tagetes patula) which acts indirectly via the host plant. Thus, the VOCs emitted by T. patula make the host plant (pepper, Capsicum annuum) repellent: during the choice tests, the aphids move towards the peppers alone but avoid the VOCs emitted by peppers previously grown intercropped for 5 days with the french marigold. Two compounds, (E)-β-farnesene (EBF) and eugenol have strong repellent properties against M. persicae.Different factors can affect the repellent effectiveness of these plants (climate, plant management, genetics). We compared the VOCs emitted by species and chemotypes and tested the individual repellent effect of VOCs. This "genotype" effect was examined by studying the olfactory behaviour of M. persicae in the presence of individual VOCs emitted by different clones of Rosemary (Rosmarinus officinalis). Five compounds are repellent, bornyl acetate, camphor, α-terpineol, terpinene-4-ol and geranyl acetone. Only the rosemary clone Voltz Splindler was found to be repellent, while the other clones also contain these 5 repellent compounds in varying proportions. It can therefore be concluded that the presence of these compounds is not sufficient to induce a disturbance of the aphid's olfactory behaviour and that the concentration, proportion or even association of VOCs present in the released olfactory bouquets are at the origin of these contrasting results. By the electropenetrography (EPG) technique, we have demonstrated a second effect of the VOCs emitted by O. basilicum in the vegetative stage and by T. patula in the flowering stage on the aphid. They strongly disrupt its feeding behaviour, in particular by reducing the duration of phloem ingestion, which results in a decrease in nutritional resources and leads to a decrease in its fertility. A fertility monitoring on detached organs has allowed us to highlight the importance of the phenological stage of the CP on the composition and efficacy of the olfactory mixture released. A final step in my work confirmed, under tunnel conditions, the effect of VOCs emitted by these two CP on the demographics of M. persicae due to a decrease in its fertility. In conclusion, this thesis highlighted that VOCs emitted into the environment of a host plant by neighbouring plants can provide a service to crops by reducing the performance of pests such as M. persicae. We have shown that variables such as chemotype or phenological stage of the CP can modify its olfactory message and provide a way to optimize this service. We have thus identified disruptive CP and VOCs repellent to M. persicae, the first step towards the development of the push component of a stimulodissuasive diversion strategy to reduce the use of synthetic pesticides against M. persicae

O trabalho teve como objetivos determinar a flutuação populacional de formas aladas e ápteras de Myzus persicae (Sulzer, 1776), Brevicoryne brassicae (Linnaeus, 1758) e Lipaphis erysimi (Kaltenbach, 1843) e avaliar a influência de inimigos naturais, de fatores meteorológicos e a distribuição vertical dos pulgões em couve, Brassica oleracea L. var. acephala DC., em Jaboticabal, SP. A amostragem de formas aladas e ápteras dos pulgões foi efetuada com armadilhas amarelas com água e coleta direta na parte aérea, enquanto os inimigos naturais foram averiguados por procura visual na parte aérea da couve e armadilhas de solo. As formas aladas dos pulgões começaram colonizar a couve em meados de maio, quando prevalesceram temperatura média de 22,6ºC, umidade relativa de 68,5% e ausência de precipitação pluviométrica. A colonização da couve por ápteros de L. erysimi iniciou-se quatro dias após a chegada dos indivíduos alados, para B. brassicae e M. persicae esse intervalo foi de 9 dias e 30 dias, respectivamente. As populações mais elevadas dos pulgões ocorreram na couve de julho a setembro, com os pulgões apresentando baixa atividade durante o verão e outono. Os ápteros de M. persicae predominaram nas folhas medianas da couve, o mesmo acontecendo com B. brassicae nas folhas apicais e L. erysimi nas basais. As aranhas, Cycloneda sanguinea (Linnaeus, 1775), Lebia concinna Brullé, 1837 e Diaeretiella rapae (Mc'Intosh, 1855) foram os inimigos naturais com maior potencial para controlarem as populações dos pulgões. A umidade relativa do ar foi o principal fator meteorológico a atuar sobre alados e ápteros dos pulgões, com a densidade populacional desses insetos diminuindo com o incremento da umidade.
The objectives of this work were to determine the populational fluctuations of alate and apterous Myzus persicae (Sulzer, 1776), Brevicoryne brassicae (Linnaeus, 1758) and Lipaphis erysimi (Kaltenbach, 1843), and to evaluate the influence of natural enemies, meteorological factors and the within-plant distributions of aphids in kale, Brassica oleracea L. var. acephala DC., cultivated in Jaboticabal, São Paulo State. Alate and apterous aphids were sampled by yellow traps of water and visual search, while natural enemies were checked by visual search of the aerial parts of kale and pitfall traps. The alate aphids began to colonize the kale crop in mid May, when prevailed medium temperature of 22.6ºC, relative humidity of 68.5% and absence of rainfall. Apterous L. erysimi began to colonize the kale crop four days after the arrival of first alate individuals, while for B. brassicae and M. persicae that interval were 9 days and 30 days, respectively. The highest populations of the aphids in the crop were observed from July to September, and they showed low activity during the summer and fall. Apterous M. persicae prevailed on the middle leaves of kale, the same were observed for B. brassicae and L. erysimi on top and basal leaves, respectively. The natural enemies that showed the greatest potential to regulate the aphid populations were: spiders, Cycloneda sanguinea (Linnaeus, 1775), Lebia concinna Brullé, 1837 and Diaeretiella rapae (Mc'Intosh, 1855). The relative humidity of the air was the major meteorological factor to act on alate and apterous aphids, the population density of them decreased with the increment of that humidity.

The Variability of Life Table of Myzus persicae (Sulzer) Abstract In order to understand the effect of different host plants on population growth, life history data of green peach aphid, Myzus persicae (Sulzer) on cabbage (Brassica oleracea L. var. capitata, L.), kale (Brassica oleracea L. var. acephala, DC.), leaf mustard (Brassica juncea Coss) and radish (Raphanus sativus L.) are analyzed based on the age-stage, two-sex life table theory. The population parameters such as intrinsic rate of increase, finite rate of increase, net reproductive rate and mean generation time are estimated by using Jackknife technique. The finite rate of increase of M. persicae on cabbage, kale, leaf mustard and radish is 1.33/day, 1.30/day, 1.37/day and 1.42/day, respectively. The finite rate of increase of M. persicae on cabbage is not significantly different from that on kale. However, there are significant difference among other finite rate of increase. The net reproductive rate is 52.7(offspring/♀), 31.4(offspring/♀), 40.6(offspring/♀) and 40.4(offspring/♀), respectively. The mean generation time is 14.5 days, 13.2 days, 11.9 days and 10.5 days, respectively.

Occurrence and emergence rate of alate of the green peach aphid, Myzus persicae (Sulzer), were influenced by temperature and initial apterous female density. Nutrition, high and low temperatures might suppress occurrence of alate individuals. The emergence rate of alate aphids was highest at 15℃.The population growth time was always shortest at high initial density of 16 aphids/leaf when tested with various temperatures. Usually the highest peak occurred at about 20 days after starting the population growth, however, peaks took longer time at low temperatures and reached earlier at high temperatures. The intraspecific competition was a scramble one. The protein content in the body of the green peach aphid was measured to be 4%∼8%, and raised with increase of temperature and declined with aphid age. The protein content was affected by temperature and population growth of aphid. The aphid population growth was hampered by high temperature at 30℃, the body weight of adult reduced to the lightest. Both M. persicae and the turnip aphid, Lipaphis erysimi (Kalt.), were found coexisted and clumped distribution in the fields. The peaks of population of both species appeared in November. Following the high population density, the field populations of aphids were heavily parasitized by parasitoids in December. The developmental time of immature stage of Aphidius gifuensis Ashmead decreased with rise of temperature. The rates of pupation and adult emergence were highest at 20℃. In field population, the emergence rate was 57∼65%. The female sex ratio was 77.2∼78.1%. The developmental duration of the immature stage of Pachyneuron aphidis (Bouche) required as long as 22.67 days at 15℃ and as shortest as 7.20 days at 30℃. The Tb of the hyperparasite was significantly higher than the parasitoid, whereas the parasitoid Tb value was higher than that of its host aphid.

The predator-prey relationship between Propylaea japonicaand Myzus persicae (Sulzer) is analyzed based on the age-stage, two- sex life table theory. The means and standard errors of the intrinsic rate of increase, the net reproductive rate, and the mean generation time for P. japonica and M. persicae are calculated by using the jackknife method. The intrinsic rates of increase for P. japonica fed on aphids of mixed stages is 0.1142/day, while the intrinsic rate of increase for that fed on aphids of the third nymphal stage is 0.1253/day. the intrinstic rate of increase for M. persicae is 0.3963/day. The age-stage specific predation rates of P. japonica were calculated based on the two-sex life table theory as well. The net predation rate of P. japonica is 1199 aphids/individual. Both of predation experiments and computer simulation showed that the non-predatory stage of predator represent "time refuge" for prey. Predation study based on the age-stage, two- sex life table revealed the detailed fluctuation of both predator and prey population.

The life table of Myzus persicae (Sulzer) reared on Brassica oleracea L. was studied under the greenhouse condition, and the average temperature and humidity during the study were 17.3 ± 1 oC and 78 ± 10% RH from 2011 January to March. The study of life table and predation rate of Oenopia sauzeti Mulsant fed on M. persicae were conducted in a growth chamber at 25oC, 65% RH, and a photoperiod of 12:12 (L:D) h. The raw data were analyzed based on the age-stage, two-sex life table to take both sexes and the variable developmental rate among individuals into consideration. The intrinsic rate of increase (r) for M. persicae was 0.2278 d-1 in the greenhouse. For O. sauzeti, the intrinsic rate of increase (r) , finite rate of increase (λ), net reproduction rate (R0), mean generation time (T), and gross reproduction rate (GRR) were 0.1431 d-1, 1.1538 d-1, 378.1 offspring, 41.5 d, and 422.4 offspring, respectively. The mean consumption rate of O. sauzeti for larval stage, female adult, and male adult were 308.7 ± 6.6, 2642.7 ±147.7, and 3090.1 ±79.6 aphids, respectively. The net predation rate (C0) was 3127.9 aphids per individual of O. sauzeti.

Based on the age-stage, two-sex life table, the intrinsic rate of increase (r), the net reproductive rate (R0) and the mean generation time (T) for silverleaf whitefly (Bemisia argentifolii Bellows & Perring) (Homoptera: Aleyrodidae) on broccoli (Brassica oleracea L. var. italica Plenk) at 26℃are 0.142day-1, 99.1 offspring/female and 32.4 days, respectively. The population parameters for the green peach aphid (Myzus persicae (Sulzer)) (Homoptera: Aphididae) are 0.283 day-1, 48.5 offspring/female and 13.7 days under the same condition. There are significant differences between population parameters of these two species. Based on the growth of both population in separation and mixture, there are exploitation competition as well as interference competition. Using the competition model based on the two-sex life table, simulation of the separated and mixed growth shows variation of weighing coefficient and susceptibility between these two species. M. persicae population suffered more in the mixed growth. Because of the susceptibility to control agents varied among life stage of insect, simulations of timing control of these two species are performed based on the two-sex life table.

Extreme climate events, such as heat wave or drought, dramatically affect ecological components and are predicted to exacerbate under climate change. In this study, we assessed the effects of heat wave on the demography of the cosmopolitan species, green peach aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae), and its parasitoid, Diaeretiella rapae (M''intosh) (Hymenoptera: Aphidiidae), in subtropical and tropical Taiwan. Daily Temperature Cycle Oscillation (DTCO.) was used as the experimental temperature setting. The heat wave (DTCO. added on 5℃ for five days) occurred in 1st, 7th, 15th day (former, middle, and later periods) of the aphid life, and the parasitoid at host 2~3 stage nymphae faced heat wave or not. Developmental time, longevity, and fecundity of M. persicae were effected by heat wave. The heat wave delayed developmental time, and reduced longevity and fecundity, and none of them succeded in reproducing, and didn’t calculate the intrinsic rate of increase (r) in former periods. The population of M. persicae was negative growth in the middle periods. Although the population of M. persicae was positive growth in later period, its r value was reduced to half. There was no mummification and emergence of D. rapae during the heat wave. The results suggested green peach aphid’s population would decrease until the end of the environmental stress. The heat wave would impact D. rapae more than M. persicae, and, thus, parasitism between the aphids and their parasitoids may be altered.

Повний текст джерелаNa Região Autónoma dos Açores, a Direção Regional dos Recursos Florestais é responsável pela produção em massa de plantas endémicas da Macaronésia com a finalidade de restaurar habitats naturais. No entanto, as plantas produzidas nos viveiros florestais são negativamente impactadas pela presença de afídeos. Os afídeos (Hemiptera: Aphididae) são, do ponto de vista fitossanitário, dos mais importantes problemas, dado que são capazes de afetar sistemas florestais e agrícolas, pois vivem em colónias de elevadas densidades, infligindo aos seus hospedeiros diversos efeitos, quer diretos quer indiretos. Com este estudo pretendemos contribuir, para o controlo biológico daquelas populações, avaliaando até que ponto as interações bióticas entre Scymnus nubilus (Coleoptera: Coccinellidae) e Aphidius colemani Viereck (Hymenoptera: Braconidae), numa estratégia de largadas multiespecíficas, poderão gerar impacto positivos, ou negativos, no controlo de populações de afídeos, em particular sobre Myzus persicae Sulzer como modelo biológico. Assim, foram realizados trabalhos laboratoriais para avaliar (i) o efeito das interações bióticas entre fêmeas adultas de A. colemani e o 4º instar larvar de S. nubilus e (ii) a preferência alimentar do 4º instar larvar de S. nubilus entre afídeos parasitados vs não parasitados. Os nossos resultados indicam que S. nubilus poder-se-á constituir como um eficiente agente de controlo biológico, especialmente em tratamentos conspecíficos, dado que a larva consome em média 50 ninfas de M. persicae em 24h. Nos testes interespecíficos verificou-se que S. nubilus interfere com o nível de parasitismo e demonstrou consumir afídeos parasitados e/ou interferência na atividade parasitária. Nos testes de preferência alimentar de S. nubilus, este demonstrou uma preferência tendencial por afídeos parasitados, o que pode dever-se à menor mobilidade e capacidade de defesa dos afídeos parasitados. Será importante num futuro próximo estudar estas interações em condições de campo.
ABSTRACT: In the Azores, the Regional Directorate for Forestry Resources is responsible for the mass production of Macaronesia endemic plants in nurseries conditions, which are later, used in restoration programs of native forestery habitats. However, almost of the plants species in the nurseries are heavily infested by aphid species affecting negatively their hosts. The aphids (Hemiptera: Aphididae), from the phytosanitary point of view, major problem, capable of affecting forest and agricultural systems because they live in colonies densely populated, inflicting direct and direct and indirect damages on their hosts. With this study, we intend to explore the extent to which it is possible to implement a program of biological control to control aphid’s populations under a multi-specific release of two biological control agents, and using Myzus persicae Sulzer as target model. To this purpose, we evaluate the effects of biotic interactions between Scymnus nubilus (Coleoptera: Coccinellidae) and Aphidius colemani Viereck (Hymenoptera: Braconidae). This study has two major objectives; to assess (i) the effect of biotic interactions in intraspecific and interspecific treatments with 4th larval stage of S. nubilus and females of A. colemani and (ii) feeding preference of parasitized and non-parasitized aphids of M. persicae by 4th larval instar S. nubilus. Our results indicate that S. nubilus may be a suitable biological control agent, especially in conspecific treatments with two predators and a prey density of 80 aphis per larvae, once they consumed on average 50 nymph of M. persicae in 24h. In heterospecific tests, it was found that S. nubilus interferes with the level of parasitism and has shown to consume parasitized aphids and / or interfere with parasitic activity. In the food preference tests of S. nubilus, we showed a tendency towards parasitized aphids, which may be due to the lesser mobility and defense capacity of the parasitized aphids.
