赴苏丹维和营区蚊虫种群密度调查研究

Investigation on density and variety of mosquitoes in China peacekeeping unit camp of United Nations Mission in Sudan

目的了解中国赴苏丹维和医疗队营区蚊虫种群构成、密度和逐月消长情况。方法外环境采用灯诱法，帐篷和室外墙壁采用吸蚊器捕捉法，室内用目测法。结果灯诱法捕获成蚊67只，伊蚊属占43．3％、按蚊属占17．9％；板房内通过综合灭蚊措施使蚊密度得到有效控制；吸蚊器于板房外墙壁捕获成蚊898只，分为5属，其中伊蚊属占52．6％、按蚊属占27．1％、库蚊属占18．2％，8～10月成蚊密度明显较11—12月高（P〈0．05）；21：00蚊活动最高，其他时段蚊密度无明显差异性（P〉0．05）。结论初步摸清了中国赴苏丹维和医疗队营区蚊虫种群构成、密度和消长情况。

Objective To know density, variety and fluctuation of mosquito month by month. Methods Mosquitoes were collected with lamp-trap in surroundings and with mosq-trap in tents and out wall. Eyeballing method in room and time to time on wall. Results 67 mosquitoes were collected with lamp-trap. Aedes was 43.3%, Anopheles was 17.9%. Mosquito density could be obviously descended by integrated killing mosquito measure in board room. 898 mosquitoes were collected with mosq-trap out wall which could be disparted five genera including Aedes （52. 6% ）, Anopheles （27. 1% ） and Culex （ 18.2% ）. Mosquito densities was higher from August to October than it from November to December. Mosquito activity was the most in 21：00 and there was no significant difference in statistics on other period of time （ P 〉 0.05 ）. Conclusion The study get a preliminary research on the mosquito genera, density and fluctuation in China peacekeeping unit camp of United Nations Mission in Sudan.
