用媒介能量探讨传疟媒介

本文报告1980~1982年在一个间日疟疫区,用同法收集各按蚊种的生态资料,算出其媒介能量。通过比较各按蚊种媒介能量的大小,推断当地的主要传疟蚊种。从调查地点共捕到13种按蚊。有四种数量较多的按蚊收全了资料,求出了媒介能量。以中华按蚊的媒介能量最大;其媒介能量的月分布与当地疟疾罹患率月分布呈正相关,推测它是当地传疟主媒。

To Explore the Principal Vector of Malaria by Using Vectorial Capacity

This paper reported the vectorial capacity of various anopheles in a tertian malaria infectious area for the period of 1980-1982. The ecological data of various anopheles, which used to take the account into vectorial capacity, were collected in the same manner. We consider that whatever species of anopheles possessing the biggest vectorial capacity, should also be probably the principal vector in that area. 13 species of anopheles had been found in the investigation region but only four species could provide enough data to be involved in the vectorial capacity. The A. sinensis became the highest. Reviewing the monthly distribution, this species as vectorial capacity showed a positive correlation with malaria incidence rate. Therefore this is regarded as the principal vector in that area.
