我们于1985年5～12月,在海口港用苏云金杆菌H14灭蚊,并进行了效果观察。该港为海南岛最大的海运港口,面积(含10个周围单位)为4KM~2,人口一万多人,地处低洼,环境治理难度大,雨季积水达三万余m~2。当地蚊种有四属19种,致乏库蚊、骚忧阿蚊、三带喙库蚊为主要蚊种,密度为43.8只/人工小时,蚊幼虫孳生地共有10多种类型;盖货物帆布孳生率达100%。盆罐52.5%,地面积水36.40%,污水沟26.7%。
From May to December 1985, we used mosquito Bacillus thuringiensis H14 to kill mosquitoes in Haikou Harbor and observed the effect. The port is the largest maritime port in Hainan Island. Its area (including 10 surrounding units) is 4KM ~ 2 and its population is more than 10,000. It is located in a low-lying area, making it difficult to control the environment and accumulating more than 30,000 m 2 of water during the rainy season. The local mosquito species are 19 genera and 4 genera, causing Culex pipiens, Caesalpinia mosseae and Culex tritaeniorhynchus as the main mosquito species, with a density of 43.8 / artificial hours. There are more than 10 types of mosquito larvae breeding habitat; Breeding rate of 100%. 52.5% pots and pots, ground water 36.40%, 26.7% ditches.
