The effectiveness of selective and complete spray applications of bendiocarb for the control of the major malaria vector, Anopheles flavirostris, was compared in an experimental hut trial in the Philippines. Selective spraying involved treatment of the vector's preferred indoor resting sites, namely, the lower wall areas, wall areas immediately surrounding the doors and windows, and eaves. Complete spraying involved treatment of all internal wall and ceiling areas, and the eaves. At intervals over a 6-month period, mosquitoes were released into the huts and recaptured within 13 h, either inside the huts, or within the interior of net traps placed over the huts. Mortality levels differed by < 8% between the spray regimens over the posttreatment period, with both regimens giving 75-100% kill of An. flavirostris during the initial 3 months. The time spent spraying and spray volume used during treatment of village houses were respectively 36 and 49% less under the selective spraying regime. Selective application of bendiocarb therefore shows considerable promise, both in terms of efficacy and cost effectiveness, for the control of An. flavirostris in the Philippines.
在菲律宾进行的一项实验小屋试验中，比较了选择性和全面喷洒残杀威对主要疟疾媒介黄喙按蚊的防治效果。选择性喷洒包括处理该媒介偏好的室内栖息场所，即较低的墙面区域、门窗周围的墙面区域以及屋檐。全面喷洒包括处理所有内墙和天花板区域以及屋檐。在6个月的时间里，每隔一段时间将蚊子放入小屋，并在13小时内重新捕获，捕获地点要么在小屋内，要么在放置于小屋上方的蚊帐陷阱内部。在处理后的时间段内，两种喷洒方式的死亡率差异小于8%，在最初的3个月里，两种方式对黄喙按蚊的杀灭率均达到75%-100%。在村庄房屋处理过程中，选择性喷洒方式的喷洒时间和喷洒量分别比全面喷洒方式少36%和49%。因此，就防治菲律宾的黄喙按蚊而言，选择性施用残杀威在功效和成本效益方面都显示出了巨大的前景。
