Description:
Parasitoid wasps (Trichogramma pretiosum) are increasingly being used as a biological control agent in agriculture. Since insecticides are often applied to the same crops, it is necessary to assess the effects of different insecticides on this insect. However, the majority of studies have focused on evaluating the lethal, but not sublethal, effects of insecticides. A new study has evaluated the sublethal effects on T. pretiosum of nine insecticides commonly used in soybean production in Brazil. Overall, just three of the nine insecticides tested did not appear to have any harmful sublethal effects on T. pretiosum. This study highlights the importance of considering sublethal, as well as lethal, effects when assessing insecticide selectivity.
