Population Density And Breeding Distribution Research Of Aedes Albopictus In Ningbo

Dengue is a vector-borne infectious disease mainly by Aedes.abopictus and Aedes.aegypyi transmission. Notifiable infectious diseases in our country for the B infectious diseases. According to WHO statistics, there are about 2.5 billion people at risk of the disease, every year about 5100 people are infected with dengue virus. China experienced the outbreak of dengue fever in recent years and more, dengue prevention and control situation is fairly grim. Since the end of last year, there spread by the Aedes Zika virus in North America, there is no effective vaccine can prevent and control the disease. Since the Ningbo region there is no report found that Ae. albopictus, dengue fever and other media in mainly Aedes albopictus.To grasp the density of Ae. albopictus season Ningbo, habitat trends, prevention and control of mosquito-borne diseases for scientific, mainly living environment of the present study Ae. albopictus larvae density trends, adult mosquitoes were analyzed.The results showed that Ae. albopictus mosquito species in the city’s total accounting for about 1.78% of each habitat and livestock shed to park higher density, from July to September is the peak of Ae. albopictus density. 2013 of the index is relatively low, for each of the different indices changed significantly over time, from June to September is the month the index is relatively high. Residential areas and urban fringe highest container index, were 10.86% and 9.84%.Ae. albopictus density is closely related to their living environment, health, and density of Ae. albopictus container index, Breteau index and housing index is closely related to the presence of both a positive correlation between the three indices. Therefore, the importance of mosquito breeding grounds of environmental governance. Through extensive patriotic sanitation campaign, mobilize the masses to carry out activities to clean their homes, pouring through the turning cylinder, reducing water containers to reduce mosquito breeding environment.Ae. albopictus density control is a key measure to reduce the risk of dengue fever and other infectious diseases, and to strengthen the monitoring of the density of Ae. albopictus, combined with environmental conditions, climatic conditions, the formation of Ae. albopictus risk early warning mechanism, the mosquito-borne density higher month should be carried out proactive forecasting, early warning information. 7--9 months, the city’s high risk of mosquito-borne infectious disease cases entered this season to focus on doing the Ae. albopictus density monitoring.
