| Summary: | Maize weevil (SitophiluszeamaisMotschulsky) is considered worldwide as a primary pest of stored products, and its control is usually carried out with synthetic insecticides. The insecticidal and repellent properties of woody leaves, fruits and stems of Meliaazedarach L. (Meliaceae) were evaluated in laboratory conditions in concentrations of 0.5; 1.0 and 2.0% (w / w) for the control of S. zeamais. The highest mortality, as contact insecticide, was obtained with leaf dust and fruits at 2% with 91% mortality. No significant fumigant activity was observed, since no treatment exceeded 30% mortality. The powders of the three plant structures showed repellent effect, although the greater activity was observed in leaf dust. Finally, the dust of woody stalks affected the germination of the wheat. The M. azedarach powder presents auspicious prospects for the control of S. zeamais. |
