目的将抗震救灾部队营区蚊、蠓、蝇、蚤的密度控制在不足为害的水平。方法利用环境治理、空间喷洒、滞留喷洒和施放菊酯类杀虫剂热烟雾的方法控制部队营区的媒介昆虫密度,密度大幅度下降后,每3 d喷洒杀虫剂和施放杀虫烟雾一次。结果采取综合防治措施后第5天,蚊的密度下降率为5%~15%,蠓的密度下降率为4%~18%,蝇的密度下降率为4%~12%,蚤的密度下降率为100%。采取防治措施后第10天,蚊的密度下降率为41%~57%,蠓的密度下降率为46%~71%,蝇的密度下降率为42%~68%。采取防治措施后第15天,蚊的密度下降率为69%~89%,蠓的密度下降率为74%~91%,蝇的密度下降率为81%~95%。结论在媒介昆虫密度很高的情况下,环境治理与持续的化学防治相结合,可有效降低昆虫的密度。
Objective To control the density of mosquitoes, slugs, flies and fleas in the camps of earthquake relief units to a level less than adequate. Methods Controlling the density and density of vector insects in the battalion of the army by means of environmental management, space spraying, sprinkler spraying and pyrethroid insecticide thermal spraying dropped pesticides and insecticidal smoke once every 3 days. Results On the fifth day after the comprehensive control measures were taken, the density of mosquitoes decreased by 5% -15%, the density decreased by 4% -18%, the density decreased by 4% -12% and the density of fleas decreased The rate is 100%. On the 10th day after the prevention and control measures were taken, the density of mosquito was reduced by 41% -57%, the density by 46% -71% and the density by 42% -68%. On the 15th day after the prevention and control measures were taken, the density of mosquitoes decreased by 69% -89%, the density decreased by 74% -91%, and the density decreased by 81% -95%. Conclusion Under the condition of high density of insect media, the combination of environmental management and continuous chemical control can effectively reduce the density of insects.
