Abstract

This study evaluated the functional response of the predator Xylocoris sordidus (Reuter, 1871) (Hemiptera: Anthocoridae) when fed with Corcyra cephalonica (Stainton, 1863) (Lepidoptera: Pyralidae) eggs contaminated with the insecticides Altacor^® (chlorantraniliprole) and Match^® (lufenuron). The experiments assessed both direct and indirect toxicity, as well as the predator behavior under varying prey densities. Logistic regression indicated a type II functional response in all treatments, with prey consumption significantly reduced when insecticides were present. Despite the toxicity observed after prolonged direct exposure, leading to 100% mortality by the sixth day, indirect exposure through feeding did not negatively affect predator longevity, and in the Match^® treatment, longevity even exceeded that of the control. Attack rate and handling time varied among treatments, with Altacor^® showing the lowest attack rate and shortest handling time. These results suggest that X. sordidus can contribute to pest control in integrated pest management strategies, particularly during the initial 72 hours following release, even in environments where chemical insecticides are applied. The findings highlight the potential compatibility of selective insecticides with biological control agents.
