Field collected fully fed adults of Phlebotomus argentipes and P. papatasi were screened in the laboratory for susceptibility to DDT, BHC, malathion, deltamethrin, permethrin, lambdacyhalothrin and bendiocarb. Pondichery strain of P. papatasi and P. argentipes showed variations in their susceptibility to insecticides. Both the species were resistant to permethrin but tolerant to DDT and malathion with LD99.99 values of 13.88, 1.92, 1.08 and 34.63, 4.69, 16.32 times more than the deterministic doses respectively. However, they were susceptible to bendiocarb with LD99.99 7.6 and 1.6 times lower than the deterministic doses. While P. papatasi was susceptible to BHC, P. argentipes showed tolerance (1.6 times). The former showed tolerance to deltamethrin and the latter exhibited resistance (34 times). It was reverse in case of lamdacyhalothrin. High susceptibility of the vector sandflies to bendiocarb suggests that this insecticide could be used effectively against OP and pyrethroid resistant populations for Kalaazar control.
在实验室中对野外采集的饱血银足白蛉和巴氏白蛉成虫进行了对滴滴涕、六六六、马拉硫磷、溴氰菊酯、氯菊酯、高效氯氟氰菊酯和仲丁威的敏感性筛选。巴氏白蛉和银足白蛉的本地治里株系对杀虫剂的敏感性存在差异。这两个物种对氯菊酯均有抗性，但对滴滴涕和马拉硫磷具有耐受性，其LD99.99值分别比确定剂量高13.88、1.92、1.08倍和34.63、4.69、16.32倍。然而，它们对仲丁威敏感，其LD99.99分别比确定剂量低7.6倍和1.6倍。巴氏白蛉对六六六敏感，而银足白蛉表现出耐受性（1.6倍）。前者对溴氰菊酯表现出耐受性，而后者表现出抗性（34倍）。在高效氯氟氰菊酯的情况中则相反。病媒白蛉对仲丁威的高敏感性表明，这种杀虫剂可有效地用于防治对有机磷和拟除虫菊酯有抗性的人群，以控制黑热病。
