Controlling container inhabiting mosquitoes such as Aedes aegypti and Ae. albopictus is often difficult because of the requirement to treat small and inaccessible cryptic sources of water where larvae are located. Autodissemination approaches based on the dissemination of insect growth regulators (IGRs) have been demonstrated as an effective means to treat these cryptic larval habitats and provide population control. Autodissemination approaches are attractive because they are based on the mosquitoes disseminating small amounts of IGRs compared to more traditional insecticide applications. While dissemination of small amounts of IGRs seems like an advantage, these approaches could lead to unintended transfer and effects on nontarget insect pollinators by delivering highly potent IGRs to nectar sources. Here we looked for the indirect and direct transfer of pyriproxyfen (PPF) to natural and artificial nectar sources and painted lady butterflies, Vanessa cardui, in semifield cages using the release of treated Ae. albopictus males or an autodissemination station. We also performed persistence tests of PPF in oviposition containers and natural and artificial nectar sources when exposed to laboratory and natural conditions. The data suggest that there is direct and indirect transfer to nectar sources and V. cardui associated with the use of autodissemination approaches. We discuss the results in the context of using autodissemination approaches for mosquito control and the potential risks these approaches may pose to nontarget insect pollinators.
