摘要
目的了解致倦库蚊和淡色库蚊在浦东机场的分布与活动规律。方法帐诱法、灯诱法、人诱法、捞勺法和人工小时法。结果致倦库蚊和淡色库蚊是浦东国际机场的优势蚊种,4-11月均有危害;灯诱法调查,季节消长呈坡型,蚊虫于4月出现,5-6月达到高峰,10-11月逐渐减少至消失;蚊虫活动(帐诱法)主要在晚上,黄昏时有群舞习性,活动高峰为日落后1～4h,白天基本不活动;刺叮(人诱法)高峰时间为21:00,叮人频率最高为42次/15min;入室蚊虫以19:00-22:00为多,入室率最高为9只/15min;幼虫主要孳生于池塘、水坑、洼地、下水道和容器等污染或干净的静止水体中。结论致倦库蚊和淡色库蚊是浦东国际机场危害人类的常见蚊种,其活动规律的研究对媒介控制和虫媒病的预警提供了技术支撑。
Objective To investigate the distribution, seasonal prevalence, diurnal rhythm, bitting and breeding of Culex pipiens quinquefasciatus and Cx. pipiens pallens in Pudong International Airport. Methods Sample collection was done by means of bednet trap, lamp baited trap, human baited trap, larvae dipping and labor hour method. Results It was found that Cx. pipiens quinquefasciatus and Cx. pipiens pallens were the dominant species of mosquitoes in Pudong International Airport, which were harmful to human health from April to November. The findings from the lamp baited trap showed a slope-shaped curve for the seasonal fluctuation of the insects, beginning in April, peaking from May to June and declining gradually from October and disappearing at the end of November. The bednet trap revealed that the insects were active predominantly in the evening and at night, with peak activity seen 1-4 h after the sunset and little movement during the day. The human baited trap indicated that the peak time of bitting was at 21：00 o’clock, with a maximum frequency of 42 times/15 min）. The number of mosquitos that entered each room was highest from 19：00 to 21：00 with the highest burglary rate being 9 mosquitos per 15 min. The larvae were mainly breeding in still sewage or clean water in ponds, pools, bottomlands, ditches and containers, etc. Conclusion Cx. pipiens quinquefasciatus and Cx. pipiens pallens are common human-biting species in Pudong International Airport. The data on the seasonal prevalence, diurnal rhythm, bitting and breeding of Cx. pipiens quinquefasciatus and Cx. pipiens pallens contribute to the prevention and control of the insects and related vector-borne diseases.
