Abstract: Objective:To study the effects of toosendanin and azadirachtin to the growth development and fecundity of Musca domestica.Methods:To feed Musca domestica by adding the drug to the foodstuff and observe in the lab.Result:Both toosendanin and azadirachtin inhibited obviously the growth of Musca domestica,causing a sluggish development and aprolonged larval period,smaller body size and hypoergy,and delayed pupation,even permanently staying in larval stage.Both toosendanin and azadirachtin treatments could cause the occurrence of some teratogenic pupae and adults,reduce the emergence rate of pupae.Both toosendanin and azadirachtin reduced Fecundity of Musca domestica,but the treatment group of toosendanin isn't significantly different from the control group(P>0.05).Both toosendanin and azadirachtin treatment groups,the hatching rate of eggs,once they were laid,had no obvious difference to that of the control group.Both treatments threw no influence on longevity of adults(P>0.05).Conclusion:Both toosendanin and azadirachtin can throw influences on growth development and fecundity of the target insects,reducing the increase rate of the experimental populations.
