【摘要】 研究了不同浓度印楝素药液对三叶草斑潜蝇存活和产卵量的影响。结果表明,印楝素对三叶草斑潜蝇卵孵化没有显著影响,对幼虫、蛹具有明显的致死作用,且对蛹的致死作用大于幼虫;对成虫表现出明显的产卵忌避作用。更多还原

【Abstract】 Effects of different Azadirachtin concentrations on Liriomyza trifolii(Burgess)survival and oviposition were studied. The results showed that azadirachtin concentration had no significant affect on egg hatch. But it could induce high larval and pupa mortality. Its lethal effect on pupa was greater than on larval. It had remarkable oviposition repellency on Liriomyza trifolii(Burgess)adult.更多还原
