1990～ 1994年我们在海南省琼中黎族苗族自治县和平地区 ,对海南省山林地带和近山丘陵区的主要传疟媒介大劣按蚊成蚊进行了为期 5年的监测。大劣按蚊为外栖性蚊种 ,在当地居民点内最早出现时间为 19:30 ,夜间活动高峰在 2 2 :0 0～ 2 3:0 0 ,室内外叮人比率为 1∶ 2 .79。山寮叮人率是村内叮人率的 15倍 ,自然感染率可高达8.3% ,雨季对大劣按蚊的孳生繁殖有极大的影响 ,溴氰菊酯浸帐村与对照村的大劣按蚊密度和经产蚊比率无显著性差异 ,在当地多种因素影响下 ,溴氰菊酯浸帐防制大劣按蚊的效果不理想。未对居民点邻近的山涧小溪及两岸边进行环境整治的开发 ,对大劣按蚊的密度和活动无影响。
From 1990 to 1994, we conducted a 5-year monitoring of the major malaria vectors of Anopheles dirus in the mountainous areas of Hainan Province and in the hilly areas of Hainan in the Heping Prefecture, Hainan Province, in the Qiongzhong Li-Miao Autonomous County. Anopheles dirus is a kind of exotic mosquitoes, with the earliest appearance time in local settlements being 19:30, the peak of night activities being between 2200 and 2300, and the indoor and outdoor bite rate being 1: 2. 79. Shanliao bite rate is 15 times the village bite rate, the natural infection rate can be as high as 8.3%, the rainy season of Anopheles breeding breeding have a great impact, deltamethrin impregnated village and control village Anopheles mosquito density and the ratio of mosquito production was no significant difference under the influence of many local factors, deltamethrin drench control Anopheles mosquitoes less than ideal. The development of environmental remediation on mountain streams and nearby banks on the settlements has no effect on the density and activities of Anopheles gigas.
