Minimizing arthropod exposure (e.g. mosquito and tick bites) is vital to protect health of outdoor workers. Personal protective measures can help protect against exposure. Here, the quantity of permethrin was evaluated for different fabric types after washing. Cone and petri dish exposure assays were used to investigate the knockdown/mortality of permethrin-susceptible and permethrin-resistant populations of mosquitoes. Permethrin-treated clothing was effective against the tested mosquito population that was susceptible to permethrin but not a permethrin-resistant population. Permethrin quantity was significantly highest in the 100% cotton fabric and for the 0 wash group. Permethrin quantity in fabrics decreased with washing. No significant differences (p > 0.05) were observed in knockdown/mortality rates for either exposure method. The protective effect of permethrin-treated clothing against mosquitoes is impacted by many factors, e.g. wash frequency, fabric type, and the susceptibility/resistance status of local mosquito populations.
尽量减少节肢动物的暴露（例如蚊子和蜱虫的叮咬）对于保护户外工作者的健康至关重要。个人防护措施可以帮助预防接触。在这里，评估了洗涤后不同织物类型的氯菊酯含量。使用锥形和培养皿暴露试验来研究氯菊酯敏感和氯菊酯抗性蚊虫种群的击倒/死亡率。氯菊酯处理过的衣物对测试的对氯菊酯敏感的蚊虫种群有效，但对氯菊酯抗性种群无效。在 100%棉织物和 0 洗涤组中，氯菊酯的含量最高。随着洗涤次数的增加，织物中的氯菊酯含量减少。两种暴露方法的击倒/死亡率均无显著差异（p>0.05）。氯菊酯处理过的衣物对蚊子的保护作用受到许多因素的影响，例如洗涤频率、织物类型以及当地蚊子种群的敏感性/抗性状况。
