Objective To investigate the density of mosquitoes in Yangzhou city, to compare the results between the mosq-ovitrap method and Breteau Index (BI) method and to provide the scientific evidence for prevention and control of dengue. Methods A mosq-ovitrap was set every 25-30 meters in a hidden and shady places in the surroundings of urban and rural areas. Adult and larval Aedes mosquitoes were collected and identified simultaneously for BI around the mosq-ovitrap set. Results In total, 150 and 50 mosq-ovitraps were set and 137, 50 were collected with 4, 3 positive traps respectively in different surrounding of urban and rural areas. The Mosq-ovitrap Index were 2.92, 6.00 respectively. At the same time, water containers in 105 and 50 households were checked around the mosq-ovitrap set, in which 11 and 8 containers were positive. The BI were 10.48 and 16.00, respectively. Based on statistical analysis, BI were higher than the Mosq-ovtrap index between which the difference was statistically significant (χ2=8.840, P=0.003). Conclusion In urban or rural areas, BI that is greater than 5 and less than 20 which indicates a relatively safe condition. The mosq-ovitrap method differs from BI method in dengue vector surveillance in this area.
Key words： Aedes mosquito density; Mosq-ovitrap index; Breteau index
