随州市不同时期按蚊种群监测研究
|
摘要
目的了解随州市主要传疟媒介现状,为开展疟疾媒介监测提供科学依据。方法采用回顾性调查和现况调查相结合的方法,调查随州市中华按蚊和嗜人按蚊分布情况,比较不同年代蚊媒密度及种群变化。结果 1985–1996年,随州市共有18个乡(镇)同时存在中华按蚊和嗜人按蚊,且嗜人按蚊占所有按蚊平均比例为52.3%;有26个乡(镇)仅存在中华按蚊。2003–2004年,嗜人按蚊仍分布在原有的18个乡(镇),其占所有按蚊的比例分别为47.0%和38.1%。2005年后再未发现嗜人按蚊,但中华按蚊密度呈上升趋势。结论随州市嗜人按蚊种群逐渐消失,中华按蚊已成为当地主要按蚊种群,在合适条件下其仍可作为疟疾传播媒介。仍需加强对媒介按蚊的监测和防控,以巩固已取得的消除疟疾成果。
Objective To evaluate the effect of malaria vector control measures so as to provide the evidence for consolidating the control effectiveness of malaria and carrying out the vector surveillance in Suizhou City. Methods The distributions of Anopheles sinensis and An. anthropophagus were investigated by the combination of retrospective review and field survey. The changes of density and population of mosquito vectors were investigated and compared among various years. Results From1985 to 1996, both An. sinensis and An. anthropophagus were found in 18 towns, and An. anthropophagus mosquitoes accounted for 52.3% of the total Anopheles mosquitoes. Only An. sinensis mosquitoes were found in other 26 towns. In 2003 and 2004, An.anthropophagus mosquitoes were found in the original 18 towns, and they accounted for 47.0% and 38.1% respectively, but in2005, An. anthropophagus mosquitoes were not found in this city. However, the density of An. sinensis presented an upward trend.Conclusions An. anthropophagus population has gradually disappeared in Suizhou City, and currently, An. sinensis is the main Anopheles population, which might be the malaria vector in suitable conditions. Therefore, the surveillance and control of Anopheles vector should be strengthened in order to consolidate the achievements of malaria elimination.
