中华按蚊人血指数三种调查方法比较

The Comparison of three Survey Methods on the Human Blood Index of Anopheles sinensis

本文对人血指数三种调查方法的结果进行了比较。通宵诱捕法估算当地中华按蚊趋吸人血为35.15%，因人饵诱捕系在毫无防护情况下进行，其结果显然偏高；就寝前、后室内捕捉法可基本捕获人、畜吸血蚊，估算人血指数（HBI）为0.065，与清晨室内搜捕法的HBI（0.066）相近。认为两者均可代表当地中华按蚊吸人血率。但前者可同时完成按蚊实际叮人率的调查，作为蚊虫传疟媒介能量评价指标，切实可行。

Three survey methods（1. bait-collection all night,2.indoorcollection early morning and 3.indoor-collection before and after going to bed）on the human blood index（HBI）are compared in this paper.The investigation shows that the HBI is 0.066 by method 2 and 0.065 by method 3.Both of these two methods can express the degree of mosquito-man biting contact detterly
