本研究采用玻璃小室法测定登革热媒介埃及伊蚊（Aedes aegypti（L.）从马来西亚的11个州到含有四种不同活性成分，即甲氧氟菊酯、右旋丙烯菊酯、右旋反式丙烯菊酯和炔丙菊酯的市售蚊香。埃及伊蚊对甲氧氟菊酯、右旋丙烯菊酯、右旋反式丙烯菊酯和炔丙菊酯的击倒率分别为14.44%~ 100.00%、0.00%~ 61.67%、0.00%~ 90.00%和0.00%~ 13.33%。总体而言，在所有人群中也观察到了0.00%至78.33%的死亡率。此外，在甲氧氟菊酯和右旋丙烯菊酯的击倒率之间以及甲氧氟菊酯和右旋反式丙烯菊酯之间检测到显著关联，表明拟除虫菊酯杀虫剂内发生了交叉抗性。总的来说，这项研究揭示了蚊香对Ae的低杀虫活性。埃及人在马来西亚的人口，因此可能提供最低限度的个人保护，防止蚊虫叮咬。
This study was conducted using the glass chamber method to determine the susceptibility status of the dengue vector, Aedes aegypti (L.) from 11 states in Malaysia to commercial mosquito coils containing four different active ingredients, namely metofluthrin, d-allethrin, d-trans allethrin, and prallethrin. Aedes aegypti exhibited various knockdown rates, ranging from 14.44% to 100.00%, 0.00% to 61.67%, 0.00% to 90.00%, and 0.00% to 13.33% for metofluthrin, d-allethrin, d-trans allethrin, and prallethrin, respectively. Overall, mortality rates ranging from 0.00% to 78.33% were also observed among all populations. Additionally, significant associations were detected between the knockdown rates of metofluthrin and d-allethrin, and between metofluthrin and d-trans allethrin, suggesting the occurrence of cross-resistance within pyrethroid insecticides. Overall, this study revealed low insecticidal activity of mosquito coils against Ae. aegypti populations in Malaysia, and consequently may provide minimal personal protection against mosquito bites.
