Melia azedarach L. extracts and their activity on Musca domestica L. (Diptera: Muscidae)

RESUMO: "Extratos de Os bioensaios mostraram inibição no desenvolvimento pós-embrionário das moscas e um signifi cativo aumento do período larva recém eclodida-adulto. Além disso, o peso pupal foi reduzido e a proporção sexual alterada. Foi observada toxicidade para os ovos das moscas. Unitermos: Extratos de planta, Diptera, Melia azedarach, regulação do desenvolvimento, atividade biológica. ABSTRACT: Crudes extracts and fractions from seeds of Melia azedarach L. (Meliaceae) have been assayed on Musca domestica Linnaeus, 1758 (Diptera: Muscidae). Thus, the postembryonic development of the fl ies was reduced and the delay from newly hatched larvae to adults had signifi cant increase. In addition, the pupal weights were reduced and the sexual ratio altered. Toxicity to fl y eggs was also observed
