某军事演习区域蚊虫综合防治措施的研究

目的控制蚊虫密度,防止虫媒传染病的发生,保障部队战斗力。方法查清演习场所周围10 km以内蚊虫孳生地的状况,采取环境治理、化学防治和个体防护相结合的综合措施。结果室外场所用超低容量喷雾和常量喷雾后1 h蚊虫密度下降率达96.1%;野营帐篷内用蚊帐浸泡剂处理蚊帐,在40 d观察期间,蚊虫停落数由试验前6.70只/帐降为0～0.43只/帐,吸血率由26.68%降为0～4.17%,对人的保护率达95%以上;值勤单兵用长效驱避剂涂抹裸露部位1,00%保护时间为6 h。结论蚊虫防治必须以环境治理为主,但在蚊虫肆虐地区,化学防治仍是快速控制蚊虫密度的重要手段,必须因地制宜,不同场所采用不同的药剂。

Integrated mosquito control in a military maneuver field

Objective To control the density of mosquitoes,prevent vector-borne disease and ensure the army power.Methods Investigating breeding sites,environment improvement,chemical control,individual protection and integrated control.Results The density of mosquitoes decreased by 96.1% one hour after ultralow volume spraying and constant spraying outdoors.The number of mosquitoes lighting on the nets decreased from 6.70 to 0-0.43 pieces per net,blood sucking rate reduced from 26.68% to 0-4.17%,and the protection was up to 95% forty days after the treatment of net with insecticides.The soldiers on duty could be protected for 6 h after the application of repellent.Conclusion Environment improvement should be the basic measure for mosquitoes control.Chemical control is still important when quick control is in need.
