内燃式电热驱虫片的药效及其性能观察

Efficacy and chouractreristics of internal combustion electric insect repelant

目的观察内燃式电热驱虫片在室内对淡色库蚊的药效和挥发性、稳定性等特性。方法室内药效试验和模拟现场药效试验分别按照GB13917.5-1992和GB13917.8-1992标准中规定的相关测试步骤进行;通过不同时间段的热处理,求出累计挥发率;采用热藏加速试验处理,给出有效含量损失率。结果累计挥发率内燃式电热驱虫片为88.15%,对照组为76.40%;损失率内燃式电热驱虫片为8.50%,对照组为6.40%。经统计学处理,驱虫片对靶生物的效果优于对照组。结论内燃式电热驱虫片具有药效持久、见效快、生物药效高、选用杀虫剂广等特点,有开发应用前景。

Objective To study the efficacy, volatility and stability of internal combustion electric insect repelant on Culex pipiens pallens in lab. Methods Indoor insecticidal efficacy tests were conducted according to the method of GB 13917.5-1992. Simulated field-tests for insecticidal efficacy were conducted according to GB 13917.8-1992. Total volatilizing rate was observed after heated for various periods. Decreasing rates for active components were obtained by heat accelerating test. Results It had better efficacy on tested insects than the control by statistics analyzing. Total volatilizing rate was 88.15 % for electric insect repelant while 76.40% for the control. Decreasing rate of active component was 8.50% for electric insect repelant while 6.40 % for the control. Conclusion The internal combustion electric insect repelant has durable efficacy, quicker and better effect, suitable for all kinds of insecticides. It is a promising product for insects control.
