摘要
目的 :观察云南南部微小按蚊的生态习性及传疟作用 ,经多年防制后的变化。方法 :人、牛诱捕。结果 :幼虫滋生于缓流占 93.2 % ,稻田占 6.8%。野外与村内叮人率比为 0 .75∶0 .65 ,牛诱捕量比为 0 .6∶0 .4。季节消长与疟疾发病曲线相吻合。结论 :微小按蚊仍为云南南部地区的主要传疟媒介。
AIM:Observation of bionomics of Anopheles minimus and its role in malaria transmission in south parts of Yunnan was conducted, and it's change for many years control.METHODS:Collected from human-bait and cattle-bait.RESULTS:The lavae breeding in slow-stream and ricefield were 93.2 % and 6.8 % respectively.Out-village and in-village human biting rate were 0.75 and 0.65 ,collections from cattle out-village in-village were 0.6 ∶ 0.4 .Relationship between the seasonal fluctuation and the curve of malaria cases was identical. CONCLUSION: Anopheles minimus was still a highly efficient vector in transmitting malaria in south parts of Yunnan.
