巴基斯坦塞赫万地区蚊蝇种群调查及蝇防治效果研究

Investigation and control efficacy of mosquitoes and flies in Sehwan Pakistan

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。
