动物屏障对人房捕蚊效果的观察

Observation on Collecting Mosquitoes in Human Rooms by Animal-Shelter in Yunnan

目的 采取动物屏障对傣族人房进行蚊虫捕捉效果观察。方法 捕蚊工具为CDC诱蚊灯通宵诱捕 ,动物屏障采用当地耕牛。结果 两灯共捕蚊 2亚科 5属 9亚属 2 2种 ,经数据分析发现 ,有动物屏障的人房捕蚊效果与无动物屏障的效果差异无显著性 (t <t0 .0 5) ;但观察发现前者捕获蚊虫数 ( 78.83只 /晚 )显著高于后者 ( 5 5 .17只 /晚 ) ;有动物屏障的人房捕获按蚊数与库蚊数基本一致 ,差异无显著性 (t <t0 .0 5) ;动物屏障捕蚊效果与当地雨量存在正相关关系(r =0 .40 3 ) ,而与当地气温有负相关关系 (r =-0 .3 6)。结论 动物屏障对傣族村庄人房防蚊效果不佳 ,建议动物屏障设置于村庄之外可能较好。

Objective To observe on collecting mosquitoes in human rooms by animal-shelter on July,2001. Methods To collect mosquitoes by CDC human rooms during nights and to use local cows as the animal-shelter under human houses. Results The collected mosquitoes belonged to 22 species,9 subgenus, 5 genus, 2 subfamilies; There was no significant difference between the animal-shelter and the non animal-shelter( t<t 0.05 ), but the numbers of anopheles( 78.833 per night) were more than those of culex( 55.167 per night) for the animal-shelter; the efficiency of collecting mosquito for the animal-shelter was almost the same as that for the non animal-shelter( t<t 0.05 ), and both the rain-fall and the temperature had relations with the animal-shelter. Conclusion The efficiencies of avoiding mosquitoes in the Dai-national house was not good with the animal-shelter method. We suggest that it may be better if we put the animal-shelter outside village.
