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.
