1. 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. 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

4. Mathematical simulation model of the velvetbean caterpillar. I. Description of the model.
Foi desenvolvido um modelo matematico de simulacao da lagarta-da-soja (Anticarsia gemmatalis Hubner, 1818), o principal inseto desfolhador da soja no Brasil, com os objetivos principais de consolidar as informacoes existentes sobre o inseto e verificar as necessidades de pesquisa sobre o mesmo. Foram utilizadas as informacoes disponiveis na literatura brasil

5. 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

6. Do different casein concentrations increase the adverse effect of rutin on the biology of Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae)?
The flavonoid rutin is recognized as playing an important role in the protection of plants against lepidopterans. Bioassays with this compound are generally carried out using artificial diets. Proteins of high energy value, such as casein, are important ingredients of insect artificial diets as a source of essential amino acids. However, such proteins can ge

7. 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

8. Detection of cry1 genes in Bacillus thuringiensis isolates from South of Brazil and activity against Anticarsia gemmatalis (Lepidoptera: Noctuidae)
The bacterium Bacillus thuringiensis (Bt) is characterized by its ability to produce proteic crystalline inclusions during sporulation. Cry1 protein has insecticidal activity and is highly specific to certain insects and not toxic to unrelated insects, plants or vertebrates. In this work, the patogenicity of twelve Bt isolates was tested against Anticarsia g

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. Purification and characterization of trypsin-like digestive proteases from the velvetbean caterpillar, involved on plant-insect interactions / Purificação e caracterização de proteases digestivas tripsina-like do intestino de lagarta da soja, envolvidas no mecanismo de interação planta-inseto
A Anticarsia gemmatalis (Lepidoptera), conhecida como lagarta da soja, é considerada a principal praga desta cultura, causando enormes prejuízos devido ao ataque herbívoro. Os danos causados pelo ataque da lagarta associados à relevância econômica do cultivo da soja para o Brasil, fomentam a busca por alternativas no controle deste inseto. Devido à im

11. 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

12. Propriedades bioquímicas e cinético-enzimáticas de cisteíno- proteases do intestino médio da lagarta da soja / Biochemistry and kinectics-enzymatics properties of cysteine-proteases of the velvetbean caterpillar midgut
Protease inhibitors that react with insect specific proteases are candidates to have their genetic code inserted in genetically modified plants. The first step to achieve this is the characterization of proteolytic enzymes of these insects intestines. Cysteine-protease of the soluble and insoluble fractions from the midgut of Anticarsia gemmatalis were chara
