Abstract:

Objective To understand the species, density, seasonality, and the influence of observation sites of mosquitoes at Tianzhu free trade zone, and to provide scientific basis for mosquitoes control and mosquitoes-borne diseases prevention. Methods CO2 light traps were applied to collect adult mosquitoes from May to October, 2015, which were then identified and classified. Pathogens were also detected. Results A total of 4 749 adult mosquitoes that belonged to 3 genera, 5 species were trapped in 2015. Culex pipiens pallens were the predominant specie at Tianzhu (94.44%). Armigeres subalbatus, Aedes vexans, and Ae. dorsalis, whose density and number were usually very low, were captured for the first time at Tianzhu. Mosquito densities were high in June and September. The densities of mosquitoes at Tianzhu west and south were higher than that at Tianzhu north. The Japanese encephalitis and West Nile virus detection results were negative. Conclusion Culex pipiens pallens were the predominate specie in Tianzhu, which deserve more attention for control.

摘要:

目的 掌握天竺综合保税区(综保区)内蚊类种群构成、密度、季节消长等情况,为蚊虫防治和预防蚊媒传染病提供科学依据。方法 2015年5-10月,采用CO2诱蚊灯法诱捕成蚊,进行种类鉴定和病原体检测。结果 2015年捕获成蚊3属7种共4 749只,淡色库蚊占捕获总数的94.44%,为该区的优势蚊种;在天竺综保区首次捕获到骚扰阿蚊、刺扰伊蚊和背点伊蚊等,但密度极低、数量极少;6、9月蚊密度较高;天竺综保区西、南监测点蚊密度高于北监测点;流行性乙型脑炎病毒、西尼罗病毒检测均为阴性。结论 天竺综保区内生境较适合蚊虫孳生,淡色库蚊为优势蚊种,应作为防控重点,需对天竺综保区首次捕获的蚊种加强监测和研究,及时建立蚊媒传染病预警预防机制。
