In Yishan County, Guangxi Province, China, where malaria and Brugian filariasis are transmitted by vectors belonging to the Anopheles hyrcanus Pallas group, a study was conducted from June to November 1986 to evaluate the effectiveness of permethrin-impregnated mosquito bednets to reduce man/vector contact. In three experimental villages a total of 246 mosquito nets were treated with permethrin EC at a dosage of 0.5 g/m2. Control bioassays (1 h exposure) of treated nets gave up to 100% mortality of Armigeres subalbatus (Coquillett), Anopheles sinensis Wiedemann and Culex tritaeniorhynchus Giles for up to 19 weeks. During 5 months evaluation in the villages, permethrin-impregnated mosquito-nets reduced the number of mosquitoes found inside nets by 99.3% for Culex quinquefasciatus Say, by 94.4% for Anopheles sinensis Wiedemann and by 75% for Anopheles lesteri anthropophagus Xu & Feng. This measure could thus be considered an appropriate means of controlling vectors in villages.
在中国广西宜山县,疟疾和布鲁氏丝虫病由赫坎按蚊帕拉斯种群的媒介传播,1986年6月至11月进行了一项研究,以评估氯菊酯浸渍蚊帐减少人与媒介接触的效果。在三个实验村庄,共246顶蚊帐用0.5克/平方米剂量的氯菊酯乳油处理。对处理过的蚊帐进行的对照生物测定(暴露1小时)显示,对骚扰阿蚊(Coquillett)、中华按蚊(Wiedemann)和三带喙库蚊(Giles)的死亡率高达100%,长达19周。在村庄进行的5个月评估期间,氯菊酯浸渍蚊帐使网内发现的致倦库蚊(Say)数量减少了99.3%,中华按蚊(Wiedemann)减少了94.4%,嗜人按蚊(Xu & Feng)减少了75%。因此,这一措施可被视为控制村庄媒介的适当手段。
