Abstract: Objective To know species composition and habitats of mosquitoes in the border area of Aedes albopictus distribution area in Shaanxi province,and to evaluate effect of mosq-ovitrap and photocatalytic mosquito and fly trap.Methods Choosing 6 different habitats in three survey sites from July to September in 2006.Putting the mosq-ovitrap to observe attracted adults and larvae of Ae.albopictus,and photocatalytic mosquito and fly trap to observe attracted adults.Results Ae.albopictus was found in Baoji and Hancheng city.Average mosquito and oviposition positive index(MOI) by mosq-ovitrap was 17.92.Reproduce fastigium of Ae.albopictus was in Augest.The highest MOI of Ae.albopictus was in hilly area and woodland,was 33.20.Total 925 mosquitoes were collected in three survey sites by photocatalytic mosquito and fly trap.8 species of 5 genera were recongnized.Culex pipiens pallens was the dominant species.It was 76.11% of the total.Cx.pipiens pallens,Armigeres subalbatus and Cx.tritaeniorhynchus distribute in all habitats investigated.Cx.tritaeniorhynchus is more in the area of breeding and cultivation.Conclusion The distribution of Ae.albopictus is same as history data.Cx.pipiens pallens,Cx.tritaeniorhynchus and Ar.subalbatus are dominant populations in this area.The mosq-ovitrap and photocatalytic mosquito and fly trap have a high attractive effect.
