摘要
胶带或胶板用于蟑螂的监测已多年 ,本实验将其与药剂联合使用 ,将不同浓度的杀虫药剂涂于胶面上 ,将被试种群的德国小蠊粘于其上 ,2 4h后观察其死亡率。根据粘胶板上的不同药剂剂量 ,可以求出被试种群的死亡———剂量曲线 ,以实验室敏感种群的LC50 做为基数 ,便能够求出该种群的抗性指数。用该种方法对采自北京地区的 4个德国小蠊种群进行抗性检测 ,同时采用传统的药膜法对该 4个种群的击倒抗性进行测定 ,将此二者的结果进行比较 ,发现 4个种群的抗性大小的趋势基本一致。
Sticky traps and/or glue boards have been used for years to monitor and control German cockroach populations.We tried to incorporate insecticide into test sticky traps and put German cockroaches onto the glue.The various dosages of the pesticides were coated onto the disk.Mortality of the cockroach was counted after 24 hours.A dose mortality curve could be developed for each insecticide.Resistance ratios were calculated with LC 50 or KT 50 values of the wild and the sensitive populations detected in the same manner.We detected insecticide resistance in four German cockroach populations from different sites of Beijing with this method and compared the results with those in the glass jar method for two insecticides.There were some differences in the ratios,but the trend was appeared in all cases,which show the method was useful in monitoring the resistance of German Cockroach.
