| description | Purified seed lectins from the legumes Canavalia brasiliensis (ConBr) and Cratylia floribunda (CFL)were tested for insecticidal activity against Callosobruchus maculatus (Coleoptera: Bruchidae)and Dysdercus peruvianus (Hemiptera: Pyrrhocoridae). ConBr and CFL caused negative effects onlarvae of C. maculatus at levels of 1% and 2% (w/w). Time of development of C. maculatus insects,grown in artificial seeds containing both lectins, was not significantly altered, but the emergencewas slightly diminished. Both lectins were resisted to proteolysis by gut proteases of C. maculatuslarvae. Artificial diets containing 1% and 2% of ConBr or CFL caused no effect on weight and survivalof D. peruvianus nymphs. Gut proteases of D. peruvianus were able to breakdown ConBr and CFLafter 2 hours of incubation. The ability of insects to digest the proteins was correlated directly withthe deleterious effect observed. |

Lectinas purificadas de sementes de Canavalia brasiliensis (ConBr) e Cratylia floribunda (CFL) foram testadas quanto a atividade inseticida sobre Callosobruchus maculatus (Coleoptera: Bruchidae) e Dysdercus peruvianus (Hemiptera: Pyrrhocoridae). ConBr e CFL causaram efeitos negativos sobre o desenvolvimento das larvas de C. maculatus nas concentrações de 1% e 2% (p/p). O tempo de desenvolvimento dos insetos crescidos nas sementes artificiais contendo ConBr ou CFL não foi significativamente alterado, entretanto a porcentagem de emergência foi diminuída. Ambas lectinas foram resistentes a ação hidrolítica de proteases intestinais de larvas de C. maculatus. Dietas artificiais contendo as lectinas não causaram efeitos deletérios sobre a massa e a sobrevivência de ninfas de D. peruvianus. Proteases intestinais extraídas de D. peruvianus foram capazes de hidrolisar ConBr e CFL após 30 minutos de incubação. A habilidade dos insetos para digerir as lectinas parece estar diretamente relacionada ao efeito inseticida observado.
