^РЕФ: The minute pirate bugs (Hemiptera: Anthocoridae) are effective biological control agents against destructive agricultural pests such as the western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) in agroecosystems around the world. One species, Orius insidiosus (Say), has proven effective in controlling thrips populations in fields and greenhouses, and serves as an integral component of many integrated pest management (IPM) programs. Three experiments were conducted using motion-tracking software and dual-choice Y-tube bioassays to determine whether direct thrips contact and thrips cues contact induced arrestant and attractant behaviors. The experiments revealed that O. insidiosus adults exhibited behavioral changes indicative of switching from extensive to intensive foraging after direct exposure to thrips prey. Similar arresting behavior was induced by the presence of thrips tracks alone. In Y-tube bioassays O. insidiosus showed preference towards arms containing tracks from western flower thrips larvae vs. clean arms, but only when direct contact with the tracks was made in the stem. Our data indicate that thrips deposit non-volatile semiochemicals that are used by O. insidiosus during foraging. These compounds have the potential to aid in O. insidiosus behavior manipulation which may help in early control of thrips populations in fields and greenhouses. Further research is necessary to determine the chemical composition of these cues and how to effectively and pragmatically integrate the inducing stimuli into biocontrol programs as part of IPM strategies. aref1
