Abstract: Objective To compare the results between the mosq-ovitrap and the Ovitrap in the field. Methods The trial was carried out in a campus in Guangzhou from August to November 2004,and from February to August 2005. One mosq-ovitraps and one ovitraps at intervals of 1 m were set every 50 m at hidden and shady spot and the positions of two kinds traps were alternated each month. Mosquitoes captured and the egg positive traps were counted and recorded on the 4^th day and the 7^th day since the installation. Results On the 4^th day since installation,the positive indices of mosq-ovitrap and ovitrap were 35.5 and 56.7 respectively; and at 7^th days,the positive indices were 53.3 and 71.5 respectively. In total,the oviposition index(OI) of the ovitraps at 7^th days was nearly 2 times of the mosquito and oviposition positive index(MOI) of mosq-ovitraps installed for 4 days. 284( 99.3 ) Aedes albopictus,and 2 Culex quinquefasciatus were captured in the 662 mosq-ovitraps installed for 4 days . The mosquito(Aedes)-trap density index(MDI) was 1.21± 1.12 ,the number of caught mosquitoes ranged from 0 to 8 in all the mosq-ovitraps. The results of the surveillance in each month indicated that there was positive correlation between the MOIs of the mosq-ovitraps set for 4 days and the OIs of the ovitraps set for 7 days (r=0.838 ,P=0.001,y=25.548+1.312x). Conclusion When the mosq-ovitraps were applied for 4 days,the MOI could reflect the population seasonal dynamic of mosquito. There was positive correlation between the MOIs of the mosq-ovitraps and the OIs of the ovitraps.
