Pesticide Toxicity to Anastrepha suspensa (Diptera: Tephritidae)

Twenty-four materials were assessed for toxicity to Anastrepha suspensa (Loew) in laboratory assays. Compounds which should be effective for managing A. suspensa were abamectin, azinphos-methyl, baythroid, bifenthrin, chlorpyrifos, emamectin, fipronil, imidacloprid, methamidophos, and spinosad. Oviposition was inhibited up to 168 h in surviving females by abamectin, baythroid, bifenthrin, fipronil, imidacloprid, methidathion, and spinosad. By varying chemistries, A. suspensa management should provide effective and responsible control with minimal environmental impact while providing opportunities for resistance management.
