目的了解中国赴巴基斯坦医疗救援队营区和灾民区蚊蝇种群及防治效果。方法电动吸蚊器捕捉室内蚊,蝇采用定面积计数法和被击倒蝇直接计数法并作蚊蝇鉴定。结果电动吸蚊器在4间教室和2个厕所共捉蚊28只。巴军驻地以食堂及其四周蝇密度最高(210只/m2),伊斯兰场所(5.7只/m2)最低;灾民区卫生条件较差,帐篷内蝇密度较高,特别是旱厕区蝇密度300～500只/m2,按高效氯氰菊酯可湿性粉剂有效成分30～50 mg/m2处理后,宿舍和伊斯兰场所的蝇密度下降为100%,其余场所下降90%以上;在救援队休息小树林药物处理30 min后,4个行军床和1个木箱表面收集被击倒的蝇297只(61.8只/m2)。结论初步摸清了中国赴巴基斯坦救援队营区和灾民区蚊蝇种群,证明在当地采取的灭蝇效果可靠。
Objective To understand the mosquito population and the control effect of mosquitoes in the camps and disaster areas of China’s medical aid teams traveling to Pakistan. Methods Electric mosquito was used to capture indoor mosquitoes and mosquitoes, and the direct counting method of flies was used to count mosquitoes and flies. Results Electric mosquito caught a total of 28 mosquitoes in 4 classrooms and 2 toilets. The density of the flies in the canteens and their surrounding flies was the highest (210 / m2) and the lowest in the Islamic sites (5.7 / m2); the hygienic conditions in the affected areas were rather poor and the density of flies in the tents was high, especially in the dry toilets ~ 500 / m2. After treatment with the active ingredient of beta-cypermethrin WP at 30-50 mg / m2, the density of flies in dormitories and Islamic sites dropped to 100% and the rest decreased by more than 90% After 30 min, 297 flies (61.8 / m2) were knocked down on the surface of four camp beds and one wooden box. Conclusion The mosquito population of mosquitoes in camps and affected areas in China’s rescue teams to Pakistan was initially found out, demonstrating that the mosquito flies were reliable locally.
