【 摘 要 】

Introduction:the knowledge of the adverse effects of the use of chemical insecticides, associated to consumer concerns regarding to the quality of food, have required studies on new techniques for control of storage pests, including the use of natural products that are less aggressive to the environment, being required in organic production and family farming.Objective:evaluate the insecticidal bioactivity of powder plant extracts and hydroalcoholic of Aspidosperma pyrifolium (Mart.) , Anadenanthera colubrine (Vell.) and rigid Licania (Benth) from leaves and stem bark of each species on the repellency / attractiveness and mortality of the Zabrotes subfasciatus (Boh.).Methods:the plants were collected in backlands of Paraiba state, Patos - PB and the insects of a population belonging to Laboratório de Armazenamento e Processamento de Produtos Agrícolas / Universidade Federal de Campina Grande, kept in a mass of beans in a chamber under controlled temperature.Results:it was verified repellency of Z. subfasciatus to all extracts, highlighting the extract of rigid L. from bark in which the Z. subfasciatus was repulsed at 82.49 %, followed by A. pyrifolium (78.88 %) and A. colubrina (77.49 %); the opposite happened with the extract of rigid L. from leaves which attracted the adult insects in 40.29 %, noting that bark extracts were superior to the leaf extracts. In relation to mortality of the insect, is not observed difference for the extracts of the leaves and barks, in the time of 24h, of Apyrifolium andrigid L., but for A. colubrina from leaves there was more efficient effects for mortality.Conclusion:the extracts were efficient in the control of Z. subfasciatus in which the A. pyrifolium extract from bark stands out in the bioactivity killing 100 % of the insects.
