The insidious flower bug, Orius insidiosus (Say) (Heteroptera: Anthocoridae) is an important surrogate species for assessing potential effects of plant-incorporated protectants (PIPs) on nontarget heterotrophic predators. In this study, a continuous dietary exposure system was optimized by assessing the effect
