Side effects on natural enemies

Pesticides can have direct effects, such as killing the natural enemies or causing their non-emergence from eggs or pupae, but they can also have indirect effects, such as reduced fertility (egg laying), problems with regard to moulting, or a repellent effect. Both direct and indirect effects have been considered in the assessment of the side effects.

Residual effect on natural enemies (persistence)

Many agents remain harmful for a certain period after application. In natural enemies, this persistence is expressed in the number of weeks during which the agent remains harmful for the natural enemies. Only after the indicated period can the parasite or predator concerned be introduced or reintroduced successfully.
