Abstract: Objective To compare the results and understand relationship between the mosq-ovitrap method and larval survey for detecting the presence of ; Aedes mosquitoes in the field. Methods The study was carried out in the cities of Foshan and Jieyang,Guangdong province,from March 2004 to November 2005. A mosq-ovitrap was set every 5 random households and their premises,or set every 25-50 meters in a hidden and shady place in the surroundings of hospitals,schools,government office buildings,factories and gardens. Larval surveys and mosq-ovitrap method were used simultaneously in the households or in the areas of 5 meters around the trap set in the surroundings. Results In households,hospitals,schools,government office buildings,factories and gardens,14 902 mosq-ovitraps were simultaneously set and 14 648 were collected back. The positive traps for adult mosquitoes was 932. The mosquito and oviposition positive index(MOI) and mosquito-trap density index(MDI) were 6.36 and 1.03± 0.89 respectively. Total 962 Aedes albopictus(99.5)and 5 Culex(0.5) were collected. The maximum of the mosquito adults captured in a single trap was 10. At the same time,8537 water containers in 14 902 households or premises (5 meters in circumference of the mosq-ovitrap) were checked,of which 844 contained the Aedes albopictus larvae. The Breteau Index,House Index and Container Index were 5.66 ,3.87 and 9.89 respectively. The MOI was 1.12 times of the Breteau Index,or 1.64 times of the House Index,or 0.64 times of the Container Index. Conclusion There is a positive relationship between the MOI and the Breteau Index,and the House Index,the container Index respectively. The MOI is particularly approximate to the Breteau Index.
