272 - Field performance of novel spatial repellents against host seeking Stegomyia

Abstract: Insecticide resistance is continually developing against the currently developed products available for mosquito control. In order to counteract it we must explore both novel chemistries and deployments of new insecticides. Here, novel spatial repellents (GMR-134 and GMR-189) were combined with the synergist TCA and applied to BG-sentinel2 traps to assess their effectiveness at repelling host seeking mosquitoes in a back yard environment. The traps were rotated over at least 6 days and we were able to show that the traps protected by GMR189+TCA and GMR-134+TCA collected fewer mosquitoes than the control traps. Furthermore, the number of (Stegomyia) Aedes albopictus was significantly less in traps protected by GMR-189+TCA and GMR-134+TCA than non-treated traps. These results demonstrate field performance of these spatial repellents and their potential to create a point of protection against host seeking mosquitoes.
