Mead-Briggs(1992) proposed a laboratory method to assess the contact toxicity of a pesticide on the cereal aphid parasitoid Aphidius rhopalosiphi De Stefani-Perez. The influence of air moisture, photoperiod, sex of insects and storage conditions on the sensitivity of this parasitoid to phosalone was studied. Results showed that insect sensitivity is the most influenced by air moisture. The storage conditions of mummies before use seems also to be an important factor.
