摘　　要：印楝素(azadirachtin)被认为是最有发展前景的植物源杀虫剂。文章主要介绍印楝素对昆虫的接触驱避、产卵驱避、拒食、毒杀、降低生殖力、生长调节等作用及其作用机理。同时也论述印楝素对烟粉虱Bemisia tabaci(Gennadius)寄主选择、产卵、孵化、若虫发育的影响。Azadirachtin is rated as one of the most promising botanical insecticides. In this paper, we summarized the current understanding of its insecticidal activities, including landing deterrency, anti-oviposition, anti-feeding, contact toxicity, fecundity-reducing, and insect-growth-regulation. Specifically, we focus on the effects of azadirachtin on host selection, oviposition, egg hatching and development of sweetpotato whitefly Bemisia tabaci （Gennadius）.
