| description | Hundreds of plant species have been studied in order to find out the active ingredient responsible for their insecticidal activity against the pests of economic importance. To verify the insecticidal activity in the husk of stem of Croton urucurana Baillon 1864 (Euphorbiaceae) against Anagasta kuehniella Zeller 1879 (Lepidoptera: Pyralidae), the methanolic (EMeOH) extract, dichloromethane fraction (FDM), ethyl acetate fraction (FAE) and crude resin, incorporated into an artificial diet were evaluated. EMeOH (0.5, 1.0 and 2.0%) and crude resin (2.0%) interfered with neither the weight nor the survival of fourth instar larvae and other analyzed parameters. FDM (2.0%) fraction caused mortality of 65%, and the artificial diet containing 2.0, 1.0 and 0.5% FAE caused 100, 55 and 68% mortality respectively when compared with the control, confirming the least efficiency rates of food conversion for FDM(2.0%) and FAE(1.0%). The tryptic analysis performed with the midgut fluid of fourth-instar larvae demonstrated that tryptic and chymiotryptic activities for the larvae fed artificial diet containing EMeOH and crude resin were not different.<br>Atualmente centenas de plantas são investigadas para se conhecer os princípios ativos responsáveis pela atividade inseticida contra as diversas pragas de importância econômica. Com o objetivo de verificar a atividade inseticida das cascas do caule de Croton urucurana Baillon 1864 (Euphorbiaceae) em relação a Anagasta kuehniella Zeller 1879 (Lepidoptera: Pyralidae), avaliou-se o extrato metanólico (EMeOH), fração diclorometano (FDM), a fração acetato de etila (FAE) e a resina in natura, os quais foram adicionados à dieta artificial. O EMeOH (0,5, 1,0 e 20,%) e a resina in natura (2,0%), não interferiram no peso, sobrevivência das larvas de 4ª ínstar, bem como nos demais parâmetros analisados. A fração FDM (2,0%) causou mortalidade de 65%, e a dieta artificial contendo 2,0, 1,0, e 0,5% de FAE causou 100, 55 e 68% de mortalidade respectivamente quando comparado com o controle, constatando-se as menores eficiências de conversão do alimento para a FDM (2,0%) e FAE (1,0%). Através do ensaio tríptico realizado com o fluido do intestino médio das larvas, foi possível verificar que a atividade tríptica e quimiotríptica para as larvas alimentadas com dieta artificial contendo o EMeOH e a resina in natura não apresentaram diferenças significativas. |
