1. Efeito da proteina arcelina na biologia de zabrotes subfasciatus (Boheman 1833), em feijoeiro.
A arcelina e uma proteina encontrada em feijoes silvestres (Phaseolus vulgaris) e que confere resistencia ao carucho-do-feijao, Zabrotes subfasciatus (Boheman 1833) (Coleoptera: Bruchidae). Estudos foram conduzidos com o objetivo de conhecer o efeito de quatro alelos da proteina arcelina (Arc1, Arc2, Arc3 e Arc4), na biologia de Z. subfasciatus. O experiment

2. Filogeografia molecular e atividade de enzimas digestivas do caruncho-do-feijão Acanthoscelides obtectus (Bruchidae:Coleoptera) / Phylogeography and molecular activity of digestive enzymes of bean-weevil, Acanthoscelides obtectus (Bruchidae:Coleoptera)
In the world, Brazil stands out as a major producer and consumer in the world of common bean, Phaseolus vulgaris, however has low productivity due to several factors among them, low technological level used in the cultivation and lack of care mainly plant grain during the storage of . Large losses in the storage of bean (P. vulgaris) are attributed to grain

3. Bioatividade de extratos etanólicos de Croton sobre Plutella xylostella (L) e ação fumigante e composição química de óleos essenciais de Croton grevioides (Baill.) sobre Zabrotes subfasciatus (Boheman). / Bioactivity of ethanolic extracts of Croton Against Plutella xylostella (L.) and fumigant action and chemical composition of essential oils from species of Croton grevioides (Baill.) Against Zabrotes subfasciatus (Boheman.)
As plantas constituem fontes naturais de substâncias inseticidas, e vêm sendo utilizadas pela humanidade desde a antiguidade. As plantas medicinais apresentam grandes quantidades de compostos secundários como alcalóides, terpenos, flavonóides e esteróides, que promovem alta resistência ao ataque de pragas e de doenças. O gênero Croton, que é consti

4. Effects of the time and temperature of storage bean grains Phaseolus vulgaris L. on the expression of the resistance to the bean weevil Acanthoscelides obtectus (Say, 1831) (Coleoptera: Bruchidae). / Efeitos do tempo e da temperatura de armazenamento de grãos de feijoeiro Phaseolus vulgaris L. na manifestação da resistência ao caruncho Acanthoscelides obtectus (Say, 1831)(Coleoptera: Bruchidae).
Aiming to evaluate the effects of the time and temperatures of storage bean grains Phaseolus vulgaris L. on the expression of the resistance to the bean weevil Acanthoscelides obtectus (Say, 1831), free and no choice tests were accomplished under laboratory conditions. The preference for oviposition and damages caused by the weevil in pods and grains were ev

5. Lima bean (Phaseolus lunatus) seed coat phaseolin is detrimental to the cowpea weevil (Callosobruchus maculatus)
The presence of phaseolin (a vicilin-like 7S storage globulin) peptides in the seed coat of the legume Phaseolus lunatus L. (lima bean) was demonstrated by N-terminal amino acid sequencing. Utilizing an artificial seed system assay we showed that phaseolin, isolated from both cotyledon and testa tissues of P. lunatus, is detrimental to the nonhost bruchid Ca

6. Protective mechanism of the Mexican bean weevil against high levels of alpha-amylase inhibitor in the common bean.
Alpha-amylase inhibitor (alpha AI) protects seeds of the common bean (Phaseolus vulgaris) against predation by certain species of bruchids such as the cowpea weevil (Callosobruchus maculatus) and the azuki bean weevil (Callosobruchus chinensis), but not against predation by the bean weevil (Acanthoscelides obtectus) or the Mexican bean weevil (Zabrotes subfa

7. Bean [alpha]-Amylase Inhibitor Confers Resistance to the Pea Weevil (Bruchus pisorum) in Transgenic Peas (Pisum sativum L.).
Bruchid larvae cause major losses of grain legume crops through-out the world. Some bruchid species, such as the cowpea weevil and the azuki bean weevil, are pests that damage stored seeds. Others, such as the pea weevil (Bruchus pisorum), attack the crop growing in the field. We transferred the cDNA encoding the [alpha]-amylase inhibitor ([alpha]-AI) found

8. Bean α-amylase inhibitor 1 in transgenic peas (Pisum sativum) provides complete protection from pea weevil (Bruchus pisorum) under field conditions
Two α-amylase inhibitors, called αAI-1 and αAI-2, that share 78% amino acid sequence identity and have a differential specificity toward mammalian and insect α-amylases are present in different accessions of the common bean (Phaseolus vulgaris). Using greenhouse-grown transgenic peas (Pisum sativum), we have shown previously that expression of αAI-1 in
