SELECTIVITY ASSESSMENT OF CHLORFENVINPHOS REEVALUATED BY INCLUDING PHYSIOLOGICAL AND BEHAVIORAL EFFECTS ON AN IMPORTANT BENEFICIAL INSECT

摘要

Selectivity is an important factor in identifying candidate pesticides to be used in crop protection since it characterizes chemicals that, while being effective against target pests, exert an acceptable impact on the other components of the environment. Extrapolated to an integrated pest management (IPM) context, selectivity implies that candidate pesticides may preserve the ability of beneficial insects to significantly control target pest populations. In the present study, we assess the physiological selectivity of the organophosphate chlorfenvinphos, used to protect cruciferous crops against the cabbage root fly, Delia radicum (Diptera: Anthomyiidae), by investigating both the lethal and sublethal effects exerted on its main parasitoid Trybliographa rapae (Hyme- noptera: Figitidae).
