Resumen
Since Tuta absoluta(Meyrick) (Lepidoptera: Gelechiidae) was detected in 2006 as a new pest in tomato crops in Spain, several natural enemies have been reported tocontrol this pest. In biological control programs, the native parasitoid Trichogramma achaeae Nagaraja&Nagarkatti (Hymenoptera: Trichogrammatidae) is used against T.absoluta. However, the most common control practice is based on use of pesticides,and in the frame of Integrated Pest Management (IPM) programs, the knowledge on the activity of insecticides towards beneficial insects is needed for its joint use. In thiswork, we evaluated lethal and sublethal effects of insecticides commonly applied on tomato crops on adults of T. achaeae. Pesticides were sprayed on tomato plants or T. Absoluta eggs till run off at their maximum field recommended concentration. Mortality was scored after 24, 48 and 72 hours, as well as beneficial capacity and percentage of emergence.
