dc.description.abstractVittatalactone, the aggregation pheromone of the striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae), is attractive to two species of squash bugs (Hemiptera: Coreidae), the squash bug Anasa tristis (DeGeer) and horned squash bug Anasa armigera (Say). In field trapping experiments in Maryland and Virginia, clear sticky traps baited with 1 mg of a synthetic 8-isomer mix of vittatalactone captured similar to 9x more of female A. tristis and of both sexes of A. armigera, whereas male A. tristis were not significantly attracted, compared to unbaited traps. A. armigera showed a distinct dose-response to vittatalactone lure loading in the late season, and this species was more attracted than A. tristis, based on comparison to captures from underneath wooden boards emplaced in adjacent fields. Results suggest that vittatalactone could be a 'keystone semiochemical' in colonization of cucurbit hosts by specialist herbivores, and may offer the opportunity for multi-species behavioral control as a component of integrated pest management in cucurbit crops.en
dc.description.notesThanks to Ashot Khrimian and Filadelfo Guzman for formulation of the mixed vittatalactone lures. We are grateful to Alex Bier and Megan Herlihy for collection of a portion of the field traps, and to the BARC West Farm Crew for cultivation and maintenance of the vegetable fields. We also thank Brian Currin and Lucas Raymond for collection and deployment of a portion of traps at the Virginia site. This work was funded in part by Southern SARE research (LS20-337).en
