目的 :了解疟疾传播中的人类和媒介按蚊的行为。方法 :在 3个固定观察点 ,对微小按蚊的栖息、叮人和夜间活动行为进行了 1年的观察 ;寻访对象 ,进行人类行为问卷调查 ,同时采样进行血清学实验 ,对资料进行统计学处理。结果 :微小按蚊栖息密度与其栖息场所附近叮人率完全相关 (r =1) ;间接荧光抗体 (IFAT)阳性率与叮人率 (r =0 .6 9)及栖息密度 (r =0 .6 2 )成正相关 ;人的露宿行为、在田棚过夜和在微小按蚊夜间活动高峰 ( 2 2∶0 0 )后上床就寝增加了疟疾感染的机会 ;IFAT阳性率不但受微小按蚊种群大小的影响 ,而且受其年活动时间和人暴露给它叮咬程度的影响。结论 :媒介和人类行为是疟疾传播中的重要决定因素。
Purpose: To understand the behavior of human and vector Anopheles in the transmission of malaria. Methods: The habitat, bite and nighttime behavior of Anopheles micropathis were observed at three fixed observation points for one year. The subjects were interviewed, the human behavior questionnaire was surveyed, the samples were taken for serological test, and the data were statistically analyzed deal with. Results: The habitat density of Anopheles stephensi was closely related to the rate of breech near its habitat (r = 1). The positive rate of indirect fluorescent antibody (IFAT) was significantly related to the rate of bite (r = 0.69) and the habitat density (r = 6 2). People’s sleeping behavior increased the risk of malaria infection after sleeping overnight in the open field and going to bed after the peak of night-time activity of Anopheles minimus (2 2:0 0). The IFAT positive rate was not only affected by the size of the Anopheles minimus population Of the impact, but also by the age of its activities and exposure to human bite it. Conclusion: Media and human behavior are important determinants of malaria transmission.
