Field bioassays were conducted to evaluate the effectiveness of different treatment combinations of permethrin-impregnated clothing and a new extended duration repellent formulation of deet against natural populations of mosquitoes in Islamabad, Pakistan. Tests were initiated 2-2 1/2 hours prior to sunset and volunteers who wore the topical repellent applied it 8 hours earlier. The most effective treatment was a combination of wearing both the permethrin-impregnated clothing and the repellent on exposed skin. This combination provided 100% protection from bites whereas volunteers wearing only treated clothing received 57% protection. Those wearing only repellent received 89% protection, but, under the biting pressure observed, this was not significantly different from the treated clothing-repellent combination.
在巴基斯坦伊斯兰堡,进行了野外生物测定,以评估氯菊酯浸渍衣物和一种新的长效避蚊胺驱避剂配方的不同处理组合对自然蚊虫种群的有效性。测试在日落前2至2个半小时开始,涂抹了局部驱避剂的志愿者在8小时前就已涂抹。最有效的处理方法是同时穿着氯菊酯浸渍衣物并在暴露皮肤上涂抹驱避剂。这种组合提供了100%的防叮咬保护,而仅穿着经过处理衣物的志愿者获得了57%的保护。仅涂抹驱避剂的人获得了89%的保护,但在观察到的叮咬压力下,这与经过处理的衣物 - 驱避剂组合没有显著差异。
