三色迷彩油添加避蚊胺对白纹伊蚊驱避效果的实验室评价

参照中华人民共和国国家标准GB/T 17322.10-1998和《军队特需药品研发勤务技术指导原则(试行)》规定的测试方法,测试了避蚊胺和水溶性二氧化钛处理迷彩油(CFP)对白纹伊蚊Aedes albopictus的驱避效果,为研发我军专用的防蚊虫迷彩油提供依据。结果表明:在3种颜色迷彩油中加入DEET后,不影响DEET的驱蚊效果;添加不同浓度DEET对蚊虫的驱避效果差异显著,20%DEET和25%DEET+迷彩油对白纹伊蚊的平均防护时间均达到或超过10 h,达到《军队特需药品研发勤务技术指导原则(试行)》规定的标准,15%DEET+迷彩油平均防护时间不足10 h,未达《军队特需药品研发勤务技术指导原则(试行)》规定的标准。研究表明:将适量DEET与迷彩油混合涂抹于皮肤可能作为演习或战时的伪装和防蚊的一种有效的综合保护措施。

The laboratory evaluation of repellent effect of camouflage face paint mixed with DEET to Aedes albopictus

In accordance with the national standards of the People＇ s Republic of China, GB/T 17322. 10 - 1998, and the＂ supporting technology guideline of special pharmaceutical research and development for the People＇ s Liberation Army＂ （hereafter 《the guidline》） , we evaluated the effectiveness of a combination of the insect repellent N, N-diethyl-3- methylbenzamide （DEET） and camouflage face paint （CFP） in repelling mosquitoes in a laboratory. The results show that CFP mixed with DEET provided effective protection against mosquitoes. CFP mixed with 20% and 25% DEET provided protection against mosquitoes for 10 hours or more, which met the requirement of the guideline. However, C FP mixed with 15% DEET provided protection against mosquitoes for no more than 10 hours, which didn＇t meet the guideline＇ s requirements. The results indicate that CFP mixed with DEET could provide both camouflage and mosquito protection during field exercises and in wartime.
