Evaluation of Cyantraniliprole and Other Commercial Fly Baits under Laboratory and Field Conditions
2015

Laboratory and field trials were performed to evaluate the attractiveness and efficacy of commercial baits (cyantraniliprole: methomyl + (Z)-9-tricosene: dinotefuran + (Z)-9-tricosene: imidacloprid granular + (Z)-9-tricosene: and imidacloprid liquid + (Z)-9-tricosene). In choice tests: flies were most attracted to cyantraniliprole bait >: dinotefuran + (Z)-9 >: methomyl + (Z)-9 bait >: imidacloprid granular + (Z)-9 bait >: imidacloprid liquid + (Z)-9 bait. Significant degradation in bait efficacy was observed after two weeks of aging excluding imidacloprid granular: which began to degrade in field conditions after one week. Cyantraniliprole: the new fly bait active ingredient in Zyrox®: had the longest time to knockdown in the laboratory tests: but on susceptible flies: achieved 95%–100% knockdown within an hour of exposure. Zyrox® was resistant to weathering for a week: and was more attractive to flies in the field when compared to methomyl + (Z)-9 bait.
