Abstract:

Objective To investigate the effect of the type of neighborhoods on the population structure and dynamics of mosquitoes. Methods The adult population dynamics and larvae breeding of mosquitoes in four different types of neighborhoods were investigated in Yangzhou City. Results The number of trapped mosquitoes was the largest in the urban villages, and more than 800 adult mosquitoes were trapped in each urban village, which was significantly higher than that of ordinary and high quality residences. Aedes albopictus and Culex pipiens pallens were dominant species (D> 10%) in the four types of residential areas, and Ae. albopictus was the most dominant species (D> 57%). The peak occurrence of Ae. albopictus in different areas occurred in early June, and it occurred again in the urban village in the middle of September. The occurrence quantity of Cx. pipiens pallens was stable in the ordinary residence and high quality residence, while in the urban village and resettlement residential area, the peak occurred in mid?October. The orders of positive rates, densities and the numbers of mosquitoes in the different types of residential areas were: the urban villages> the resettlement residence> the ordinary residence> the high quality residence. The water vat had the highest positive rate in all kinds of larval habitats, followed by tires and green belt with garbage water. Conclusions The main mosquito species in the four different types of residential areas are all Ae. albopictus and Cx. pipiens pallens, but the positive rate, density and the number of mosquitoes in the different types significantly change, especially in the urban villages, the number and the occurrence peak are significant different from those in the other types of residential areas.

摘要: 目的 明确不同类型住宅区对蚊虫种群结构及发生动态的影响。方法 选取扬州市区4种不同类型住宅区开展蚊幼孳生及成蚊种群动态的调查。结果 诱捕成蚊总量以城中村最多,诱捕数均在800只以上,显著高于普通住宅和高档小区。4类住宅区中,白纹伊蚊与淡色库蚊均为优势种(D > 10%),诱捕数量最多为白纹伊蚊(D > 57%)。不同小区白纹伊蚊发生高峰期均出现在6月上旬,但城中村在9月上中旬再次出现发生高峰。淡色库蚊在普通住宅区和高档住宅区发生量基本稳定,而城中村和安置小区在10月中旬则出现明显的发生高峰。不同类型小区间蚊虫阳性率、密度以及孳生地数量顺序均表现为城中村>迁安置小区>普通住宅区>高档住宅区。在各类孳生地中缸的阳性率最高,其次为轮胎和绿化带垃圾积水。结论 不同类型住宅区蚊虫种类均以白纹伊蚊和淡色库蚊为主,但孳生地、阳性率及成蚊数量等均随住宅类型不同有明显变化,特别是城中村蚊虫发生量和高峰期均与其他住宅区类型有所不同。
