云南人房三带喙库蚊CDC和UV诱蚊灯捕捉效果观察

目的　评估CDC和UV诱蚊灯夜间人房三带喙库蚊捕捉效果。方法　根据拉丁方设计方案 ,把诱蚊灯置于寝室和客厅 ,每晚轮流置灯。结果　共捕获库蚊属蚊虫 6种 62 4只。其中三带喙库蚊属于最常见的蚊种 (4 19只 ) ;CDC和UV灯捕捉蚊虫效果差异无显著性 ,但当地降雨量与CDC捕捉效果存在较强的正相关关系 ,而与UV灯捕蚊效果呈弱的负相关。结论　无论是CDC诱蚊灯还是UV诱蚊灯都可以作为云南省三带喙库蚊种群密度监测的有效方法。

Relative Efficacy of CDC and UV Light-traps for Indoor Collection of Culex (Cx.) tritaeniorhychus in Yunnan, P.R.China

Objective The efficacy of CDC and UV traps for the collection of Culex (Cx.) tritaeniorhynchus was evaluated in overnight in door collection. Methods The traps were placed in bedrooms and sitting rooms and rotated nightly approximately following a Latin square design. Results A total of 624 mosquitoes of the genera Culex were trapped comprising 6 species. Most common was Cx.tritaeniorhynchus with 419 individuals trapped. There was no significant difference in the efficiency of CDC and UV traps although there was a stronger positive correlation between mosquitoes collected in CDC lamps and rainfall, whereas, there was a weak negative correlation between UV lamps and local rainfall. Conclusion We suggest that either CDC or UV light traps provide an efficient method to monitor the population of Cx.tritaniorhychus in Yunnan province.
