Abstract: Objective To investigate the community structure of mesquitoes and their ecological distribution at Hancheng city in 2006,and to evaluate efficacy of the mosq-ovitrap for monitoring Aedes albopictics in the field.Methods Using human baited net trap,light trap and mosq-ovitrap method for adults,and container method for larvae investigation.Results Mosquitoes collected from Hancheng city belonged to 5 genera 7 species,Human were attacked mainly by Ae.albopictus,Culex pipiens pallens,Armigeres subalbatus,Culex tritaeniorhynchus.The positive container index of larvae investigation was 34.38.The density of adults by human baited net trap method was 7.16 individuals per hour,1.13 individuals per hour by light trap method.The positive mosquito index of mosq-ovitrap was 15.32% in the field,the average amount of adults were 1.37 per trap,and the oviposition index by mosq-ovitrap was 14.41%.The positive mosquito index in September was higher than that in others and was 18.25%.The oviposition index was also the highest in September and was 21.25%.The oviposition index by mosq-ovitrap was higher than that by white paper cups(χ2=45.14,P<0.001).The density of adults was the highest at the special places(worn type deposit places,junk recycle bin,and so on),and in the village was higher than in the urban,in the area for rest and recreation was higher than in cultivition area.The positive container index of larvae at the village was higher than at the urban,in the area for rest and recreation was higher than in cultivition area.Conclusion Ae.albopictus,Cx.pipiens pallens,Ar.subalbatus andCx.tritaeniorhynchus were dominant population attacking human in this area.The mosq-ovitrap had a high attractive effect to Ae.albopictus adults and eggs.It can be applied for monitoring Ae.albopictus.The investigation provided some basic information for controling mosquitoes.
摘要: 目的 调查韩城市蚊类种群构成及生态习性,现场应用诱蚊诱卵器并评价其效果。方法 成蚊调查采用帐诱法、诱蚊灯法和诱蚊诱卵器法,蚊幼调查采用容器法。结果 韩城市区捕获蚊虫5属7种,侵袭人类蚊虫以白纹伊蚊、淡色库蚊、骚扰阿蚊和三带喙库蚊为多。蚊幼调查容器指数34.38;成蚊帐诱密度为7.16只/人工小时,诱蚊灯诱蚊密度为1.13只/h。诱蚊诱卵器仅诱到白纹伊蚊,平均诱蚊指数15.32%,平均每个诱蚊诱卵器捕获白纹伊蚊1.37只,平均诱卵指数为14.41%;7-9月观察期间,9月诱蚊、诱卵指数均最高,分别达18.25%和21.25%,且平均诱蚊数也高于其他月份。诱蚊诱卵器诱卵指数与配对同步的一次性纸杯相比差异有统计学意义(χ2=45.14,P<0.001)。成蚊密度特殊场所最高,农村居民区高于城市居民区,休闲活动区高于养殖耕种区;蚊幼调查容器指数亦是农村居民区高于城市居民区,休闲活动区高于养殖耕种区。结论 白纹伊蚊、淡色库蚊、骚扰阿蚊、三带喙库蚊是该地区危害人类的主要蚊种;诱蚊诱卵器具有较好的诱蚊指数和诱卵指数,可以作为白纹伊蚊监测方法,该调查为蚊虫防制提供了生态学依据。
