【摘要】：目的检测驱蚊帐驱、灭蚊效果。方法按NY/T 1151.4-2012《农药登记卫生用杀虫剂室内药效试验及评价第4部分驱蚊帐》开展驱蚊帐室内接触筒药效检测和模拟现场药效检测,对经不同洗涤次数的驱蚊帐的药效结果用SPSS11.5进行χ2检验和相关性分析。结果实验室接触筒实验中,样品1在经0、10、20次洗涤后,对致倦库蚊的1 h击倒率为77.7%、28.8%和0,24 h致死率为57.9%、17.2%、0;样品2则为91.8%、90.4%、74.7%和88.1%、80.3%、29.4%,不同洗涤次数间驱蚊帐对致倦库蚊杀灭效果的差异均有统计学意义(P0.05)。模拟现场实验中,样品1和样品2经洗涤20次后对致倦库蚊的12 h击倒率分别为57.7%和29.9%,24 h死亡率分别为57.7%和29.9%。结论洗涤影响驱蚊帐的驱灭蚊效果,实验方法的统一有利于对驱蚊帐产品开展效果评价。
[Abstract]:Objective to detect the effect of mosquito net drive and mosquito control. Methods according to NY/T 1151.4-2012, the laboratory efficacy test and evaluation of insecticides for public health use were carried out according to NY/T 1151.4-2012 part 4. The efficacy of indoor contact tube and simulated field efficacy test were carried out. The results of mosquito repellent account with different washing times were analyzed by 蠂 2 test and correlation analysis with SPSS11.5. Results in the laboratory contact tube test, sample 1 was washed after 20 times of washing. The 1-hour knock down rate of Culex pipiens quinquefasciatus was 77.728% and the fatality rate was 57.9% and 17.20.The second sample was 91.8% and 80.3%, respectively. There were significant differences in the efficacy of mosquito nets for Culex pipiens quinquefasciatus among different washing times (P 0.05). In the simulated field experiment, the 12h knockdown rates of sample 1 and sample 2 were 57.7% and 29.90.24 h respectively after washing for 20 times to Culex pipiens quinquefasciatus, and the mortality rates were 57.7% and 29.9%, respectively. Conclusion washing affects the effect of mosquito repellent and the unification of experimental method is helpful to evaluate the effect of mosquito net.
