采用d-丙烯菊酯简化幼虫杀灭生物测定法，对在神户县、福冈县（福冈和北九州市）、长崎县（对马市）和冲绳县（本岛、与那国岛、石崎岛及其附近孤岛）采集的白纹伊蚊种群进行拟除虫菊酯类杀虫剂抗性调查。神户市神户港周边的4个采集点和对马岛南部出原港周边的3个采集点均提示拟除虫菊酯类杀虫剂敏感性有所降低。虽然敏感性指数不高，但冲绳本岛2个采集点对拟除虫菊酯类杀虫剂的敏感性也有所下降。石垣岛和与那国岛蚊群对拟除虫菊酯类杀虫剂的敏感性未见明显下降。在本研究收集的蚊子样本中未检测到电压敏感钠通道（VSSC）中单个kdr（敲低抗性）突变。
Pyrethroid resistance in Aedes albopictus was investigated for several colonies collected in Hyogo prefecture (Kobe city), Fukuoka Prefecture (Fukuoka and Kitakyushu city), Nagasaki Prefecture (Tsushima city), and Okinawa prefecture (Main island, Yonaguni island, and Ishigaki island with its vicinity solitary islands) by the simplified larval knockdown bioassay using d-allethrin. Reductions in the pyrethroid susceptibility were suggested at 4 collection sites in the area around Kobe port, Kobe city and 3 collection sites in the area around Izuhara port, southern part of Tsushima island. Although the susceptibility indice were not high, reduction in the pyrethroid susceptibility was also noted at 2 collection sites in Okinawa main island. No conspicuous reductions in the pyrethroid susceptibility was noticed in the mosquito colonies collected in Ishigaki island and Yonaguni island. Not a single kdr (knockdown resistance) mutation in the voltage-sensitive sodium channel (VSSC) was detected in the mosquito samples collected in the present study.
