Повний текст джерелаThe main purpose of this study was to identify the natural enemies of Lonomia obliqua Walker, 1855, the caterpillar responsible for the hemorrhagic syndrome in human beings. From immatures of L. obliqua, collected in the field and reared in the laboratory, insects of the orders Diptera, Hymenoptera and Hemiptera, and also viruses and nematodes, were obtained. Based on the knowledge of the localities where hemorrhagic accidents were registered, the insect habitats were recognized. Comparing biotic and abiotic characteristics of these localities, generally rural, ones with those of the end of the XIX century, when the municipalities were created, an attempt was made to discuss the main factors might have influencing the increase of the species population.

Повний текст джерелаThis study aimed to identify the interactions of Bt cotton expressing Cry1Ac (Bollgard®), with the predator Podisus nigrispinus Dallas (Hemiptera: Pentatomidae), in resistance management of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) to lambda-cyhalothrin in two conditions: absence and presence of the insecticide imidacloprid. Larvae of S. frugiperda were used from the following conditions: resistant (1) and susceptible (2) strains to lambda-cyhalothrin fed Bollgard® cotton leaves (DP 404 BG); and resistant (3) and susceptible (4) strains to lambda-cyhalothrin fed non-transgenic cotton leaves (cultivar DP4049). The results of this study revealed that in the absence of imidacloprid, independent of treatment, the behavior of predation was best represented by the type III of functional response, because the attack rate increased linearly in all conditions studied (a = bN). There were differences between the handling time (Th) of females of the predator who received larvae of S. frugiperda susceptible to insecticides previously fed non-transgenic cotton in relation to other treatments. The density of 16 larvae/predator, the number of larvae preyed by female of P. nigrispinus was significantly higher in larvae of S. frugiperda resistant to lambda-cyhalothrin, fed on Bt cotton or non-Bt compared to susceptible larvae fed non Bt cotton. Moreover, when we offered 16 larvae of S. frugiperda to the predator, the number of larvae predate were significantly lower in larvae susceptible to lambda-cyhalothrin that were fed non-Bt cotton, compared to larvae that were previously fed on transgenic cotton. In the presence of imidacloprid, the predatory behavior of P. nigrispinus was affected by the neonicotinoid imidacloprid, and the asymptotic curve type II was the one that best described the data of the functional response. In the presence of imadacloprid, handling time (Th) of females of the predator did not differ among treatments. However, the attack rate was represented by a decrease due to the increase of the density of larvae offered. Regardless of the treatment (strain of S. frugiperda or cultivar of cotton), the predation larvae of S. frugiperda by females of P. nigrispinus when exposed to imidacloprid was significantly lower, especially at density of 16 larvae/predator. Given these results, the research reinforces the fitness cost associated to lambda-cyhalothrin resistance as well as Bt cotton affected the rate of predation on larvae of S. frugiperda by females of P. nigrispinus, only at the highest density tested (16 larvae/predator). The behavior of predation on larvae of S. frugiperda by females of P. nigrispinus was affected by insecticide imidacloprid.

Повний текст джерелаNeem extracts were nanoformulated with several types of nanoparticles and polymers in a tentative to reduce the biodegradation of neem active compounds and improve their residual effect. These nanoformulations were tested against Spodoptera frugiperda and their efficacy compared to a commercial product. The polymers poly(-caprolactone) (PCL), poly(- hidroxibutirate) (PHB) and poly(methyl methacrylate) (PMMA) were used in the quantities 0.25, 0.50 and 0.75g and two sorts of nanoparticles (capsules and spheres). Tween®80 and poly(vinyl alcohol) (PVA) were utilized as surfactants. The nanoformulations were produced as aqueous suspension and powder and further diluted before application. These nanoformulations were sprayed on artificial diet offered to second instars of S. frugiperda, and on corn plants which had their leaves offered to first instars. The efficacy of the different formulations was tested by assessing larval mortality and weight 10 days after treatment. When applied to artificial diets, reduced larval weight was observed, but four of them caused 40 to 46% mortality when applied on corn plants. The four most effective nanoformulations were further tested to evaluate their effects on S. frugiperda larval feeding preference and their residual effect. Three bioassays were set up using corn leaves treated with these, wich were offered to larvae at days 1, 3 and 7 after spraying (DAS), having the larval mortality and weight assessed 10 days after larval exposure. Simultaneously, choice tests for larval feeding preference (treatment x control) were carried out using corn leaf discs 1, 3 and 7 DAS. Feeding preference was evaluated by using a preference index calculated after the assessment of the leaf area fed by the larva 24h after exposure. The residual effect of the neem nanoformulations was lower than the commercial product evaluated. Only one nanoformulation and Organic Neem® were feeding deterrents to S. frugiperda, but only in the first day after the treatment. Although the nanoformulations caused larval mortality and weight reduction, their efficacy was not any better than that of the commercial product tested.

Повний текст джерелаThe velvetbean caterpillar, Anticarsia gemmatalis, is considered a major insect pest of soybean. For its control, an alternative to chemical methods is the microbial control, inserted into the pest biological control. Thus, the objective of this study was to isolate fungi from contaminated A. gemmatalis caterpillars and evaluate the pathogenic potential of isolated fungal cultures. For the fungus that caused the greatest mortality percentage of larvae exposed, enzymatic production capacity and production feasibility were found. Still, pathogenicity was evaluated and LC50 and LC90 from the best formulation obtained were established. The fungi isolation occurred from caterpillars on mummification stage, obtained in the central region of Rio Grande do Sul. Larvae mortality, allied to observation of mummification stage, lead to identify the species as Aspergillus nomius presenting the best results (about 95% mortality) among the 20 isolated-fungi. There was no growth of this fungus in culture media rich in chitin and lipids. However, there was growth in a media containing protein, which might suggest that the fungus is a good protease type enzyme producer. Testing to evaluate A. nomius production feasibility, the average spore s concentration (conidia mL-1) in all treatments were similar, with the majority stayed with 1010 conidia.mL-1. Visually, the treatment with 25% water volume per rice volume (50mL), addition of casein in the medium and adding of 6 mL of spore suspension of the fungus A. nomius, which resulted in 2.88 x1010 conidia mL-1, the rice was looser and, therefore, more aired, which may have resulted in a trend toward to a better fungus development. It was evaluated the pathogenicity of this formulated, yielding a high level of mortality among A. gemmatalis larvae, similar to results obtained when spore suspensions originated were applied directly from the fungus growth plates. Yet, at the same conidia concentration mentioned, but testing various dosages, values around 2,23x107 and 1,46x1010 mL.lagarta-1 were obtained, corresponding to LC50 and LC90, respectively, estimated by probit method. Finally, it is concluded that A. nomius presents a high potential regarding to a possible use as A. gemmatalis biological control agent in soybean crops. However, because it is a fungus with pathogenic potential for humans and other native fauna animals, it is necessary further studies related to aflatoxin production by this pathogen and its effects on the environment.
A lagarta-da-soja, Anticarsia gemmatalis, é considerada o principal inseto-praga dessa cultura. Para o seu controle, uma alternativa aos métodos químicos é o controle microbiano, inserido dentro do controle biológico de pragas. Assim, o objetivo deste trabalho foi realizar o isolamento de fungos de lagartas de A. gemmatalis contaminadas e avaliar o potencial patogênico das culturas fúngicas isoladas. Para o fungo que ocasionou a maior porcentagem de mortalidade das lagartas expostas, foi verificada a capacidade de produção enzimática e a viabilidade de produção. Ainda, foi avaliada a patogenicidade e foram estabelecidas a DL50 e a DL90 da melhor formulação obtida. O isolamento dos fungos se deu partir de lagartas, em estágio de mumificação, obtidas na região central do Estado do Rio Grande do Sul. A mortalidade das lagartas, aliada à observação de estágio de mumificação nas mesmas, serviu para identificar a espécie Aspergillus nomius como apresentando o melhor resultado (cerca de 95% de mortalidade) dentre os 20 fungos isolados. Não se observou o crescimento desse fungo em meios de cultura ricos em quitina e lipídios. Porém, houve crescimento em meio contendo proteína, podendo-se sugerir que o fungo é um bom produtor de enzimas do tipo proteases. No teste visando avaliar a viabilidade de produção de A. nomius, a concentração média (conídios.mL-1) de esporos em todos os tratamentos foi semelhante, sendo que a maioria ficou na casa de 1010 conídios.mL-1. Visualmente, no tratamento com 25% de volume de água por volume de arroz (50mL), adição de caseína no meio e adição de 6 mL de suspensão de esporos do fungo A. nomius, e que resultou em 2,88x1010 conídios.mL-1, o arroz ficou mais solto e, com isso, mais aerado, o que pode ter resultado numa tendência de melhor desenvolvimento do fungo. Foi avaliada a patogenicidade desse formulado, obtendo-se um alto nível de mortalidade em lagartas de A. gemmatalis, semelhante aos resultados obtidos quando foram aplicadas suspensões de esporos originadas diretamente das placas de crescimento do fungo. Ainda, na mesma concentração de conídios mencionada, porém testando-se várias dosagens, foram obtidos valores em torno de 2,23x107 e 1,46x1010 mL.lagarta-1, correspondentes à CL50 e CL90, respectivamente, estimadas utilizando-se o método de Probit. Por fim, conclui-se que A. nomius apresenta um alto potencial com vistas a uma possível utilização como agente de controle biológico de A. gemmatalis em cultivos da soja. Porém, por se tratar de um fungo com potencial patogênico para o homem e para outros animais da fauna nativa, é necessário aprofundar estudos relacionados à produção de aflatoxinas por esse entomopatógeno e seus efeitos no ambiente.

A espécie Sarsina violascens (Herrich–Schaeffer, 1856) (Lepidoptera: Lymantriidae) é relatada como praga primária em plantios de eucalipto e teve sua primeira ocorrência registrada em 1975. No período de 2006 a 2009 houve grandes surtos dessa praga, causando desfolhamento intenso em plantios de eucalipto no norte da Bahia. Apesar dos estudos feitos no passado terem considerado espécies de eucalipto, há pouca informação sobre a suscetibilidade de clones híbridos de eucalipto à mariposa violácea. O presente trabalho teve por objetivo avaliar a biologia de S. violascens em diferentes espécies e híbridos de eucalipto e em diferentes temperaturas, além de avaliar a eficiência de entomopatógenos no controle de S. violascens. No experimento 1 a biologia de S. violascens foi determinada nas espécies Eucalyptus grandis, E. urophylla e dois híbridos de E. grandis x E. urophylla (‘urograndis’). Os parâmetros avaliados foram duração e viabilidade dos estágios larval, pupal, adulto e de ovo e do ciclo total. No experimento 2 foi selecionada a espécie E. urophylla como padrão e avaliou-se o efeito de diferentes temperaturas (18, 22, 26 e 30oC) no desenvolvimento de S. violascens, avaliando-se os mesmos parâmetros anteriores. Os resultados obtidos no experimento 1 revelaram que E. urophylla ofereceu melhores condições para odesenvolvimento de S. violascens, com maior viabilidade larval (85,3 %), pupal (78,7 %) e de ovos (72,6 %), e menor duração do ciclo total (54,4 dias). A espécie E. grandis foi considerada a menos adequada ao desenvolvimento de S. violascens, revelando baixas viabilidades larval (29,2 %) e pupal (28,9 %).

Defoliator lepidopterous are one of the main Eucalyptus pest groups in Brazil. There are records of caterpillars outbreaks since 1940, with important occurrences during 1980’s to 1990’s. The species Sarsina violascens (Herrich–Schaeffer, 1856) (Lepidoptera: Lymantriidae), named as violet moth, is related as pest in eucalypts plantations since 1975 and during 2006 to 2009, this species has occurred in outbreaks, causing intense defoliation in eucalypt plantations in Northern Bahia, Brazil. Despite studies in the past have considered species of eucalyptus, there is little information about susceptibility of Eucalyptus hybrid clones to violet moth. This study aimed to determine the biology of S. violascens in different species and hybrids of eucalyptus and in different temperatures. The insects were observed diary to evaluate life cycle in different species of eucalyptus (experiment 1) and in different temperatures (experiment 2). In experiment 1 were tested the following species: Eucalyptus grandis, E. urophylla and two hybrids of E. grandis x E. urophylla (‘urograndis’). The parameters evaluated were: duration and viability of larvae, pupae, adult and eggs phases and total life cycle. In experiment 2 was chose the species E. urophylla as standard and evaluated the effect of temperatures of 18, 22, 26 and 30oC, considering the same previous parameters. The results obtained in experiment 1 showed that E. urophylla offered better conditions to S. violascens development and reproduction, due the higher larvae, pupae and eggs viability, and shorter total life cycle duration. The species E. grandis was considered as less adequate to S. violascens development and reproduction, with low larvae and pupae viability. To the two hybrid clones, the results were intermediary comparatively with tested species. In experiment 2 temperature of 18°C showed the most adequate to S. violascens...

A lagarta Spodoptera frugiperda (Smith, 1797) (Lepdopitera: Noctuidae) é praga na cultura do milho, afetando em até 60% os rendimentos de grãos. Uma das formas de controle dessa praga é por meio do controle biológico, sendo as vespas predadoras uma alternativa viável . Desta forma, objetivou-se avaliar a resposta olfativa da vespa social Polybia fastidiosuscual (Saussure) (Hymenoptera: Vespidae) para voláteis liberados por plantas de milho e/ou da lagarta S. frugiperda. Utilizando um olfatômetro em Y, foram realizados bioensaios comportamentais para verificar a resposta comportamental das vespas sociais aos voláteis liberados por lagartas S. frugiperda, por plantas de milho, por plantas de milho induzidas com lagartas Spodoptera frugiperda e plantas de milho injúrias mecânicas e/ou tratadas com regurgito de lagartas ou água. Observou-se que as vespas sociais não tiveram preferência significativa quando ofertou-se, ar, lagartas, plantas de milho sem indução ou plantas de milho injuriadas mecanicamente tratadas com água. No entanto, as vespas preferiram plantas induzidas por lagartas S. frugiperda ou plantas injuriadas mecanicamente tratadas com regurgito de lagartas durante os intervalos de 5-6 horas e 24-25 horas. O mesmo não foi observado quando as plantas foram induzidas por lagartas ou injuriadas mecanicamente tratadas com regurgito de lagarta no intervalo de 1-2 horas. Estes resultados foram confirmados quando ofertou-se os extratos plantas de milho induzidas por lagartas S. frugiperda ou plantas de milho injuriadas mecanicamente tratadas com regurgito de lagartas após 5-6 horas de indução versus o hexano como controle. Em uma segunda fase os extratos de plantas de milho sem indução, plantas de milho com a presença de S. frugiperda por 1 hora, plantas de milho com a presença continua de S. frugiperda e de plantas de milho injuriadas mecanicamente tratadas com regurgito de lagartas foram quantificados por cromatografia gasosa acoplada a detecção por ionização de chamas (CG-DIC) e analisados por cromatógrafo gasoso acoplado a espectrômetro de massas (CG-EM) utilizando o gás hélio como gás de arraste. Os dados foram coletados e avaliados com o software ChemStation. E a identificação dos compostos dos extratos das plantas de milho foi feita por comparação dos tempos de retenção no CG-DIC com os dos padrões usando coluna apolares e cálculo do índice de Kovats.
The caterpillar Spodoptera frugiperda (Smith, 1797) (Lepdopitera: Noctuidae) is a pest in corn, affecting up to 60%, the grain yield. One way to control this pest is through biological control, and predatory wasps a viable alternative. Thus, we aimed to evaluate the olfactory response of the social wasp Polybia fastidiosuscula (Saussure) (Hymenoptera: Vespidae) to volatiles released by maize plants and / or caterpillar S. frugiperda. Using a olfactometer-Y, behavioral experiments were conducted to verify the behavioral response to volatile social wasps released by S. frugiperda larvae by corn plants, induced by corn plants with caterpillars Spodoptera frugiperda and corn plants mechanical injuries and / or treated with caterpillars regurgitate or water. It was observed that the wasps did not have significant social preferably when offered up, air, caterpillars, corn plants without induction or mechanically injured maize plants treated with water. However, wasps preferred induced by S. frugiperda larvae or mechanically injured plants treated with caterpillars of regurgitation during intervals 5-6 hours and 24-25 hours plants. The same was not observed when plants were induced by caterpillars or injured mechanically treated with caterpillar regurgitate in the range of 1-2 hours. These results were confirmed when offered up corn plant extracts induced by S. frugiperda larvae or corn plants injured overflow, mechanically treated larvae after 5-6 hours of induction versus hexane as control. In a second phase extracts of corn plants without induction, corn plants with the presence of S. frugiperda for 1 hour, corn plants with the continued presence of S. frugiperda and corn plants injured mechanically treated regurgitate Crawler were quantified by gas chromatography-flame ionization detection (GC-FID) and analyzed by gas chromatography coupled to mass spectrometry (GC-MS) using helium as the carrier gas. Data were collected and evaluated with the ChemStation software. And the identification of compounds of extracts of maize plants was made by comparison of retention times in GC-FID with patterns using nonpolar column and Kovats index calculation.

The results obtained in experiment 1 showed that E. urophylla offered better conditions to S. violascens development and reproduction, due the higher larvae, pupae and eggs viability, and shorter total life cycle duration. The species E. grandis was considered as less adequate to S. violascens development and reproduction, with low larvae and pupae viability. To the two hybrid clones, the results were intermediary comparatively with tested species. In experiment 2 temperature of 18°C showed the most adequate to S. violascens...

Повний текст джерелаDifferent bioassays were carried out aiming to evaluate the potential of using Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) to manage Pseudoplusia includens (Walker, 1857) and Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae). Among those bioassays there were the strains selection, biological characteristics and parasitism capacity, thermal requirements, establishment of ideal number of parasitoids to be released per number of pest eggs, parasitoid dispersal capacity, amount of time that the parasitoids remain active in the field after releasing and pesticide selectivity to the parasitoid. Throughtout the species/strains selection of Trichogramma and Trichogrammatoidea it was possible to determine that Trichogramma pretiosum, strain collected in Rio Verde (RV), showed the best biological performance among the tested species/strains. Trichogramma pretiosum RV development time, when it was reared in eggs of both pest species, was inversely related to the increase in temperature. T. pretiosum RV reared in A. gemmatalis eggs had not its emergency (%) modified by temperature changes, however, when it was reared in P. includens eggs, it had a lower emergency (%) at 32oC. The lower temperature threshold (Tb) was lower for T. pretiosum RV in P. includens eggs (10.6oC) when compared to T. pretiosum in A. gemmatalis eggs (11.6oC) and consequently the thermal constant (K) was also different being 152 and 128 GD for P. includens and A. gemmatalis eggs, respectively. The estimated number of generations of T. pretiosum RV in eggs of both species varied along soybean crop season being 21 and 20 generations for Rio Verde, GO and 22 and 21 generations for Barreiras, BA in P. includens and A. gemmatalis eggs, respectively. The parasitism rhythm of T. pretiosum RV was changed by the tested temperatures, concentrating the parasitism during the first days except at 18oC in P. includens eggs and at 18 and 20oC in A. gemmatalis eggs when the parasitism occurred during the whole parasitoid lifespan. The total parasitism was influenced by the temperatures, being higher among 22 and 28oC in P. includens eggs and among 25 and 28oC in A. gemmatalis eggs. The higher parasitism rate is reached at 51.2 and 25.6 female parasitoid per P. includens and A. gemmatalis eggs, respectively, accordingly to what was established at greenhouse trials. T. pretiosum RV dispersing capacity in soybean fields is 8.0 m and its dispersal area is 85.18 m2. Therefore, it is required a minimum of 117 parasitoid releasing points per hectare in order to have a homogeneous parasitoid distribution in the field. After T. pretiosum RV release, parasitoids remained in the soybean crop for 12 days. However, the parasitism was effective up to 4 days. The results from this research for P. includens and A. gemmatalis eggs indicate that the control of both pests might be possible using the T. pretiosum RV. Insecticides, herbicides and fungicides commonly used in soybean fields impacted differently the parasitism of T. pretiosum RV, being classified since harmless (class 1) to harmful (class 4).
