Impacts of pyriproxyfen on the efficacy of Encarsia inaron Walker (Hym: Aphelinidae) on control of Trialeurodes vaporariorum Westwood (Hom: Aleyrodidae)

[摘要]  This study attempts to establish the combined effect of Encarsia inaron in junction with pyriproxyfen against Trialeurodes vaporariorum under greenhouse conditions. In the present study, we have found pyriproxyfen to be compatible with E. inaron in the control of the greenhouse whitefly. Whitefly mortality in the presence of the parasitoid was 93.9%, significantly higher than the mortality in the control group (37.2%). A non-significant difference between pyriproxyfen versus E. inaron performance was detected. Pyriproxyfen showed a negligible negative impact on the parasitism rates of E. inaron. It could be concluded that the biological control is being used as a complement to, rather than a substitute for, chemical control
