Abstract The encyrtids Aenasius advena Comp. and Blepyrus insularis (Cam.) are the key parasitoids of the striped mealybug Ferrisia virgata (Ckll.) in many countries.

The other chemicals such as endosulfan (0.07%), phosalone (0.07%) and dichlorvos (0.20%) showed lesser toxic residual activity while… Expand
