Abstract：Objective To observe the effect of different solutions on monitoring Aedes albopictus by mosquito ovitrap,so as to provide scientific basis for the monitoring and control of Ae.albopictus.Methods From May to October 2024,the mosquito ovitrap method was used to monitor Ae.albopictus using sodium bicarbonate solution,lactic acid solution,urea solution and dechlorinated water.Chi-square tests were used to compare the differences among different solutions and different habitats.Results The mosquito ovitrap index(MOI)of the four solutions from high to low were dechlorinated water(13.47),sodium bicarbonate solution(11.26),urea solution(9.95)and lactic acid solution(6.57),there was statistical significance differences between the groups(χ2=16.075,P＜0.05).There was no statistical difference in the monitoring results of sodium bicarbonate solution,urea solution and dechlorinated water(χ2=3.672,P＞0.05).The monitoring effect of lactic acid solution was significantly lower than that of sodium bicarbonate solution,urea solution and dechlorinated water.There was no statistical difference in the monitoring results of the four solutions in hospital,government agencies,parks and hotels(χ2=0.485,P＞0.05;χ2=7.574,P＞0.05;χ2=3.752,P＞0.05;χ2=1.752,P＞0.05),and was statistical significance differences in residential areas(χ2=11.356,P＜0.05).Conclusions For using mosquito ovitrap for monitoring Ae.albopictus,dechlorinated water is the best option,being both inexpensive and readily available.
