摘要:

目的 研究疟疾传播媒介中华按蚊的飞行距离,为消除疟疾媒介按蚊控制范围提供基础资料。方法 采用标记-释放-重捕技术,在河南省永城市对中华按蚊的飞行距离进行初步研究;用电动吸蚊器捕捉中华按蚊3000只,进行荧光标记染色;将标记好的中华按蚊转移至释放点释放;释放后连续10 d进行回收捕捉,回捕后进行荧光检测。结果 研究期内,共释放3000只绿色荧光粉标记的中华按蚊,回收25只,重捕获率0.83%;释放后不同时间回收数量不同,释放后当天回收1只(4.0%),第1天14只(56.0%),第2天8只(32.0%),第3天1只(4.0%),第6天1只(4.0%),其他时间均未捕获到;不同方位回收数量不同,村东部与南部回收数量明显多于西部和北部;不同距离回收数量不同,80%的标记中华按蚊在100 m范围内捕到;荧光标记中华按蚊最大飞行距离为400 m。结论 在国内首次应用标记-释放-重捕技术来研究中华按蚊的飞行距离;荧光标记释放后中华按蚊的重捕获率较低,最远飞行距离为400 m,大多数在100 m范围内捕到;因此,当消除疟疾过程中出现疟疾疫点时,疫情的最大处理范围应覆盖以疫点为圆心,500 m为半径的地区,其中,疫点周围100 m内的范围需做重点处理。

Abstract:

Objective To study the flight range of Anopheles sinensis and provide evidence for the development of control measures for malaria elimination in China. Methods The mark-release-recapture technique was used to preliminarily study the flight range of An. sinensis. The 3000 wild An. sinensis were captured and marked with green fluorescent powder and released at the specific site of Yongcheng city. Subjects were recaptured for ten successive days using light traps and fluorescent detection. Results Twenty-five of the 3000 released An. sinensis were recaptured, resulting in a recapture rate of 0.83%. The number of recaptured An. sinensis varied over time; one on day 0 (the day of release), fourteen on day 1, eight on day 2, one on day 3, and one on day 6. No marked An. sinensis were recaptured on the other days. The number of recaptured An. sinensis also varied by location; the number of recaptured An. sinensis was significantly higher to the east and south of the village than to the west and north. Eighty percent of the marked An. sinensis were recaptured within 100 m of the initial release site with a maximum flight distance of 400 m. Conclusion This is the first study of An. sinensis flight-range patterns using the mark-release-recapture technique in China. In this study, the recapture rate was low, and most marked An. sinensis were recaptured within a 100 m radius of the release site with a maximum flight distance was 400 m. Given preliminary data on An. sinensis flight patterns, the management area of disease control efforts in future malaria epidemics should cover a radius up to 500 m from an epidemic focal point, with most resources concentrated within a 100 m radius.
