ObjectiveTo determine the effect of comprehensive measures at reducing mosquito density in residential parking lot， and to provide scientific evidence for exploring a new mosquito density control mode in parking lot.
MethodsDuring April to October in 2018， a package of measures were implemented in the observation group， including designating a full-time staff， combination of property management and mosquito eradication work， continual clean-up of breeding ground， appropriate use of pesticide， education and training of pest control knowledge， and so on. No intervention was conducted in the control group. Then we observed the effect of the above measures in reducing mosquito density.
ResultsAfter the implementation of the comprehensive measures， the average adult mosquito density and infant positive rate of ponding mosquitoes in the residential parking lot in the observation group were significantly lower than those in the control group. The mosquito positive rate in rainwater well， sewage well， drainage ditch and intercepting ditch in the observation group was significantly lower than that in the control group. There were no statistically significant difference between the observation group and the control group in the adult mosquito density and the infant positive rate of ponding mosquito in April.
ConclusionThrough a package of comprehensive prevention and control measures， mosquito density in the parking lot at residential areas can be effectively reduced. However， there are still some resistances in the implementation process of measures， which need to be constantly optimized to achieve better on-site prevention and control effect.
