The susceptibility to six pyrethroid insecticides (permethrin, deltamethrin, alpha-cypermethrin, cypermethrin, lambda-cyhalothrin, and bifenthrin), each at the recommended concentration, was evaluated for two stable fly species- (Linnaeus, 1758) and Picard, 1908 (Diptera: Muscidae)-through tarsal contact using a World Health Organization (WHO) cone bioassay procedure. The field populations of were collected from the Songkhla and Phattalung provinces, while were collected from the Phattalung and Satun provinces in Thailand. The stable flies were exposed to insecticide-treated filter paper for 30 min, and their knockdown counts at 30 min and 60 min and mortality counts at 12 h and 24 h were recorded. The and Songkhla and Phattalung populations were moderately susceptible to pyrethroids, as indicated by the 24 h mortality. Nonetheless, the Satun population of was completely susceptible to permethrin, with 100% mortality, and showed the lowest susceptibility to deltamethrin and bifenthrin. The results indicate the generally low susceptibility of stable flies to pyrethroids in the southern provinces of Thailand.
通过跗节接触，利用世界卫生组织（WHO）的锥形生物测定程序，对两种厩螫蝇（1758年命名的厩螫蝇和1908年命名的类厩螫蝇，双翅目：蝇科）进行了评估，以测定它们对六种拟除虫菊酯类杀虫剂（氯菊酯、溴氰菊酯、高效氯氰菊酯、氯氰菊酯、高效氯氟氰菊酯和联苯菊酯）在各自推荐浓度下的敏感性。厩螫蝇的野外种群分别采自泰国宋卡府和博他伦府，而类厩螫蝇的野外种群采自泰国博他伦府和沙敦府。将厩螫蝇暴露于经杀虫剂处理的滤纸上30分钟，并记录它们在30分钟和60分钟时的击倒数量以及在12小时和24小时时的死亡数量。宋卡府和博他伦府的厩螫蝇种群以及类厩螫蝇种群对拟除虫菊酯类杀虫剂呈中度敏感，这一点从24小时死亡率可以看出。尽管如此，沙敦府的类厩螫蝇种群对氯菊酯完全敏感，死亡率达100%，并且对溴氰菊酯和联苯菊酯的敏感性最低。结果表明，泰国南部省份的厩螫蝇对拟除虫菊酯类杀虫剂普遍敏感性较低。
