摘要:

目的 了解“8·7”甘肃省舟曲特大山洪泥石流灾区内涝积水及其他积水容器蚊虫孳生情况,为蚊虫及相关传染性疾病的防制提供技术支撑。方法 蚊幼虫密度调查采用勺捕法,使用10%高效氯氰菊酯、安备1%颗粒剂投放于现场。结果 共调查各类内涝积水、建筑工地蓄水池(箱)及其他积水容器13处,密度最高21.0只/勺,最低0.3只/勺,平均6.7只/勺。10%高效氯氰菊酯和安备1%颗粒剂灭后第1天的平均密度下降率分别为87.30%和90.14%,第2天为96.83%和98.59%。结论 2种杀虫剂对灾区各类水体中的蚊幼虫均有良好的杀灭效果,为甘肃省今后应对突发公共卫生事件应急处理病媒生物防制提供了科学依据。

Abstract:

Objective To investigate the mosquito density in pooled water and containers in the mud-rock flow disaster areas of Zhouqu county and provide technical support for the control of mosquito and associated infectious diseases. Methods The density surveillance was conducted by the spoon method, and 10% beta-cypermethrin and 1% Abate larvicide were deployed on the spot for larval control. Results Upon investigation of thirteen water bodies and containers, including those in construction areas, the average density of mosquito larvae was 6.7, with the highest of 21.0 and lowest of 0.3 per spoon. After pesticide deployment, the average density declined by 87.30% and 90.14% at day 1, and down by 96.83% and 98.59% by day 2, with 10% beta-cypermethrin and Abate, respectively. Conclusion The two insecticides were effective in larval mosquito control in various water bodies. They would bring potential benefits in vector control of the public health emergency response system in Gansu province.
