1. Effect of seed treatment with insecticides on the control of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in soybean
RESUMO A lagarta-do-cartucho é um dos principais insetos-praga no Brasil. Assim, o presente trabalho teve por objetivo avaliar o efeito do tratamento de sementes no controle de Spodoptera frugiperda nas infestações iniciais da cultura da soja. O delineamento experimental foi inteiramente casualizado, com quatro amostras replicadas de seis tratamentos inse

2. Protease inhibitory, insecticidal and deterrent effects of the trypsin-inhibitor benzamidine on the velvetbean caterpillar in soybean
Abstract The recognition of protease inhibitors with insecticidal activity is important as a basis for the development of mimetic peptides with potential use as biorational insecticides. We sprayed benzamidine on soybean plants and assessed whether this potent synthetic trypsin-inhibitor has protease inhibitory, insecticidal and deterrent effects on the velv

3. SPRAY DRIFT AND CATERPILLAR AND STINK BUG CONTROL FROM AERIAL APPLICATIONS WITH ELECTROSTATIC CHARGE AND ATOMIZER ON SOYBEAN CROP
ABSTRACT: The use of aerial application with electrostatic charge is an alternative to improve the quality of insecticide applications in soybean crop. The objective of this study was to evaluate the drift and chemical control of the caterpillar and stink bug complex promoted by aerial applications of insecticide in the soybean crop, using electrostatic spra

5. Agronomic performance, chromosomal stability and resistance to velvetbean caterpillar of transgenic soybean expressing cry1Ac gene.
The objective of this work was to analyze the agronomic performance and chromosomal stability of transgenic homozygous progenies of soybean [Glycine max (L.) Merrill.], and to confirm the resistance of these plants against Anticarsia gemmatalis. Eleven progenies expressing cry1Ac, hpt and gusA genes were evaluated for agronomic characteristics in relation to

6. Efeito de doses de Baculovirus anticarsia no consumo e na utilizacao de alimento por larvas de Anticarsia gemmatalis Hubner (Lepidoptera: Noctuidae).
Foram avaliadas quatro doses de Baculovirus anticarsia, ou seja: 0,5, 2,7, 15 e 80 corpos poliedricos de inclusao (CPI)/mm cubico de superficie foliar, visando verificar se a relacao existente entre doses e mortalidade de Anticarsia gemmatalis tambem se reflete no consumo e na utilizacao do alimento por essa especie. Todas as doses testadas reduziram signifi

7. Produtividade de genótipos de soja sob infestação da lagarta-da-soja e de percevejos
Three soybean experiments, one for each maturation group (early, semi-early, and medium), were installed in the field in Assis, State of São Paulo, during the 2003/2004 growing season to evaluate damage caused by Anticarsia gemmatalis (Hubn.) and by the soybean stink bug complex, Euschistus heros (F.), Piezodorus guildinii (West.), and Nezara viridula (L.).

8. Seleção de genótipos resistentes de amendoinzeiro a Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) com base em análises multivariadas
The velvetbean caterpillar Anticarsia gemmatalis Hübner attacks peanut leaves, and the use of resistant varieties has directly contributed to ecological and economic aspects of pest control. The aim of this work was to select resistant peanut genotypes to A. gemmatalis using cluster analyses (dendogram obtained by Ward's methods and K-means) and Principal C

9. Estudo morfológico e histoquímico do intestino médio de larvas de Anticarsia gemmatalis (Hübner 1818) (Lepidoptera: noctuidae) suscetíveis e resistentes ao AgMNPV alimentadas com genótipos de plantas resistentes a insetos
The velvetbean caterpillar, Anticarsia gemmatalis (Lepidoptera: Noctuidae) is a pest of soybean. To control this insect have been employed as technical biological control by nucleopolyedrovirus (AgMNPV) and the resistance of plants with cultivars that have a complex of chemicals (flavonoids), wich can make them toxic to insects. The midgut is considered the

10. Plasticidade fenotípica e susceptibilidade a patógenos em Anticarsia gemmatalis (Lepidoptera: Noctuidae) / Phenotypic plasticity and susceptibility to pathogens in Anticarsia gemmatalis (Lepidoptera: Noctuidae)
Investimentos profiláticos em defesa a parasitas e patógenos envolvem um custo. Assim, é esperado que organismos os usem somente quando requeridos, por exemplo quando em altas densidades populacionais, onde o risco de transmissão de parasitas e patógenos pode ser aumentado. Se o risco para o individuo aumenta com a densidade populacional, é esperado qu

11. Interação de técnicas para o manejo fitossanitário de Anticarsia gemmatalis (Lepidoptera: Noctuidae) / Techniques interaction for pest management of Anticarsia gemmatalis (Lepidoptera: Noctuidae) control
Several Trichogramma (Hymenoptera: Trichogrammatidae) species parasitizing Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) eggs, the main soybean defoliator in Brazil. The egg parasitoid Trichogramma atopovirilia Oatman &Platner (Hymenoptera: Trichogrammatidae) is an agent of biological control of the soybean caterpillar Anticarsia gemmatalis Hubner (

12. PONTAS DE PULVERIZAÇÃO E VOLUMES DE CALDA NO CONTROLE DE Anticarsia gemmatalis HÜBNER, 1818 e Piezodorus guildinii (WESTWOOD, 1837) NA CULTURA DA SOJA Glycine max / EFFECT OF SPRAY NOZZLES AND VOLUMES IN THE TWO INSECTICIDES CONTROL OF Anticarsia gemmatalis HÜBNER, 1818 AND Piezodorus guildinii WESTWOOD, 1837 IN SOYBEAN CROP (Glycine max)
The aim of the study were: a) to evaluate the effect of spraying nozzles on two insecticides controlling velvetbean caterpillar, Anticarsia gemmatalis, stink bug, Piezodorus guildinii and b) to evaluate the effect of spray volume in the efficiency of insecticide control velvetbean caterpillar and stink bug in soybean crop. In the experiment of spraying nozzl
