The purpose of this study was to evaluate the use of boric acid, imidacloprid, ivermectin, or abamectin incorporated into sugar baits as oral toxicants for adult phlebotomine sand flies. Variable toxicity of insecticide-sugar bait solutions to adult male and female sand flies was demonstrated, based on male female median lethal concentration values of 0.10-0.08, 6.13-9.53, and 9.03-18.11 mg/liter of imidacloprid, ivermectin, and abamectin, respectively. Complete control of sand flies could not be achieved with as high as 40 g/liter of boric acid in sugar bait solution; concentrations >40 g/liter were found repellent to the sand flies. Uranine O (a fluorescent tracer dye that can be used to measure the ingestion of sugar baits by sand flies) did not interact negatively with imidacloprid, ivermectin, or abamectin when it was combined with the insecticides in a sugar bait. Also, incorporation of imidacloprid, ivermectin, or abamectin into sugar baits did not reduce the effect whether adult male and female sand flies fed on these sugar baits. We propose that imidacloprid, ivermectin, or abamectin could be used to control adult sand fly populations with targeted use of insecticide-treated sugar baits.
本研究的目的是评估掺入糖饵中的硼酸、吡虫啉、伊维菌素或阿维菌素作为成年白蛉口服毒剂的使用情况。基于吡虫啉、伊维菌素和阿维菌素对雄性和雌性白蛉的半数致死浓度值分别为0.10 - 0.08、6.13 - 9.53和9.03 - 18.11毫克/升，证明了杀虫剂 - 糖饵溶液对成年雄性和雌性白蛉具有不同的毒性。在糖饵溶液中加入高达40克/升的硼酸也无法完全控制白蛉；发现浓度>40克/升对白蛉有驱避作用。铀O（一种可用于测量白蛉对糖饵摄取量的荧光示踪染料）与吡虫啉、伊维菌素或阿维菌素在糖饵中与杀虫剂混合时不会产生负面相互作用。此外，将吡虫啉、伊维菌素或阿维菌素掺入糖饵中并不会降低成年雄性和雌性白蛉取食这些糖饵的效果。我们建议，通过有针对性地使用经杀虫剂处理的糖饵，吡虫啉、伊维菌素或阿维菌素可用于控制成年白蛉种群。
