In a rural area of Zaire, the whole population of a village was protected by deltamethrin-impregnated mosquitoes bednets. A similar village was observed as a control. Biting rates for mosquitoes were recorded in both villages. The principal man-biting species were Mansonia africana, Mansonia uniformis, and Aedes aegypti. In the village protected by the impregnated mosquito bednets, the number of Mansonia bites was reduced 96% indoors and at a lesser rate outdoors. Biting rates of Ae. aegypti dropped to 0 indoors, but the outdoor biting rate remained unchanged. It is concluded that the reduction in mosquito bites is not only caused by the repellent action of the deltamethrin but also by a reduction in mosquito numbers.
在扎伊尔的一个农村地区，一个村庄的全体村民都受到了经溴氰菊酯处理的蚊帐的保护。观察了一个类似的村庄作为对照。记录了两个村庄蚊子的叮咬率。主要叮咬人的蚊种是非洲曼蚊、同型曼蚊和埃及伊蚊。在受到经处理的蚊帐保护的村庄，室内非洲曼蚊的叮咬次数减少了96%，室外减少的比例较小。埃及伊蚊的室内叮咬率降至零，但室外叮咬率保持不变。得出的结论是，蚊虫叮咬次数的减少不仅是由溴氰菊酯的驱避作用引起的，也是蚊虫数量减少的结果。
