What is Insecticide selectivity to two species of Trichogramma in three different hosts, as determined by IOBC/WPRS methodology about?
## Abstract **BACKGROUND:** The use of __Trichogramma__ species is a potential key strategy in integrated pest management. However, its effectiveness depends on the use of chemicals that do not interfere with parasitism and parasite population growth. Here, a study was made of the effects of synthetic insecticides on __Trichogramma pretiosum__ and __Trichogramma exiguum__ in different hosts (__Ephestia kuehniella, Plutella xylostella__ and __Spodoptera frugiperda__) and the influence of International Organisation for Biological Control (IOBC/WPRS) methodology in selectivity studies using different __Trichogramma__ species. The insecticides used were commercial formulations (triflumuron at a concentration of 0.2 mL L^−1^ water, etofenprox at a concentration of 0.47 mL L^−1^ water and endosulfan at a concentration of 7.5 mL L^−1^ water); the control treatment consisted of distilled water. Eggs attached to cardboard cards were offered to parasitoids inside glass cages. Parasitised eggs, parasitism and adult emergence rates and parasitism reduction were evaluated. **RESULTS:** Endosulfan and etofenprox, classified as class‐4 toxic products, were extremely toxic to the parasitoids.
