驱蚊花露水对常见蚊虫的驱避作用

目的研究以自产Ｄｅｅｔ（Ｎ，Ｎ－二乙基间甲基甲酰胺）为有效成分配制的驱蚊花露水对本地区常见吸血蚊虫的驱避作用。方法将自产和进口Ｄｅｅｔ分别配成２％、５％和１０％的花露水剂型，分别喷涂于实验动物的腹部皮肤及志愿者裸手，连续观察各浓度驱蚊花露水在６ｈ内对蚊虫的驱避效果。结果自产Ｄｅｔ配制的２％驱蚊花露水保护时间为２ｈ。５％和１０％的驱蚊花露水在６ｈ内的有效保护率为１００％。结论自产和进口Ｄｅｅｔ对蚊虫的驱避作用无显著性差异。５％的驱蚊花露水为有效驱蚊的最佳选择。

Repellent effectiveness of a novel mosquito-repellent-perfume against mosquitoes

Objective To investigate the effectiveness of a novel mosquito-repellent-perfume of mainly compoed of Deet(N,N-diethl-meta-toluamide)synthetized by ourselves against mosquitoes.Methods The mosquito-repellent-perfume treated with Deet with the synthetized by ourselves and the import in 2%,5% and 10% concentrations,was sprayed on the skin of mice and voluneers,and the repellent effect against mosquitoes was observed continually within 6 hours.Results The protection time of mosquito-repellent-perfume treated with our Deet 2% concentration was only 2h.The mean effective protection rates of mosquito-repellent-perfume contained 5% and 10% Deet synthetized by ourselves were 100% within 6h.Conclusions The novel mosquito-repellent-perfume mixed with Deet at 5% concentration is practicable for individual protection against mosquitoes.There is no significant difference between our synthetized Deet and the imported one.
