Effects of Azadirachtin Missible Oil on Liriomyza trifolii(Burgess) Survival and Oviposition

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.
