Abstract: Objective To acquire the density and seasonal fluctuation information of Culex tritaeniorhynchus in Jingdezhen city, and provide data for following study. Methods Light traps were used to get surveillance data from residential areas, parks, hospitals, farmyards and livestock sheds in Jingdezhen city twice per month between 2010 and 2014. LSD-t and SNK-q were used to analyze the data by SPSS 19.0. Results Culex tritaeniorhynchus was the predominant mosquito specie in Jingdezhen, accounting for 51.26% of the mosquito population. The declining trend in 2010 to 2014 was significant (y=-749.1x+1 509 397.4, R²=0.917, P=0.010). The temporal distribution of Cx. tritaeniorhynchus showed a single peak in June, which the density was 3.28 per light per night. Although the density in livestock sheds and farmyards was much higher than other habitats, the declining trend kept the same. The maximum peak in June appeared in all habitats while the farmyard had a secondary peak in August. Conclusion In this study, we acquired the density, habitat, interannually fluctuation and seasonal variation of Cx. tritaeniorhynchus in Jingdezhen city, and provided the basic data for the follow-up work.
