In this study, six insecticide dust formulations were laboratory-tested in soil mixtures ranging in concentration from 40 to 1,280 parts per million (ppm) against a proven vector of bubonic plague, Oropsylla montana (Baker). Pulicidal effects of the six insecticides, which included three organophosphates, two carbamates, and a pyrethroid, were compared by LD(50) values at both ambient and 75% RH. Permethrin (Pyraperm 455 dust), a pyrethroid with a LD(50) less than 40 ppm, demonstrated the most effective pulicidal action for the 13-wk trial period, followed in order by chlorpyrifos, bendiocarb, propetamphos, diazinon, and carbaryl.
在本研究中，在浓度范围为百万分之40至1280（ppm）的土壤混合物中对六种杀虫剂粉剂配方进行了实验室测试，以对抗腺鼠疫的一种经证实的传播媒介——蒙大拿山蚤（贝克）。通过在环境湿度和75%相对湿度下的半数致死剂量（LD50）值比较了六种杀虫剂的杀蚤效果，这六种杀虫剂包括三种有机磷、两种氨基甲酸酯和一种拟除虫菊酯。氯菊酯（Pyraperm 455粉剂），一种半数致死剂量小于40 ppm的拟除虫菊酯，在13周的试验期内表现出最有效的杀蚤作用，其次依次是毒死蜱、仲丁威、丙溴磷、二嗪农和西维因。
