Long-term suitability of an alternative host for rearing the sugarcane stalk borer parasitoid .

The continuous utilisation of an alternative host may influence parasitoid performance across successive generations due to conditioning in natal hosts. (Olliff) has successfully been reared using L. pupae as a feasible alternative host.

Predation and behavioral changes in the neotropical lacewing Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) exposed to lambda-cyhalothrin.

Pyrethroid insecticides are widely recommended against various defoliating pest species, but usually lack efficacy against sucking pests such as aphids, which are preferred prey of lacewing larvae. Interaction of pyrethroids and lacewings are likely to occur in fields infested by both defoliating and sap-sucking pests and should provide a complementary control. Therefore, our study aimed to estimate dose-mortality curves and behavioral changes by Chrysoperla externa exposed to lambda-cyhalothrin.
