摘要: 目的:复配灭蟑药笔新配方,提高药笔对蜚蠊的杀灭效果,以取代抗药性日益增高的单配方灭蟑药笔。方法:药膜接触法,2种药笔按国家标准分别进行药效测定,即在实验室采用相同的药膜板,2种药笔分别按15mg/m2均匀地涂抹于药膜板上,在室内常温自然存放24h、半年、1年、1年半和2年,每一个时段用两种敏感品系试虫(德国小蠊和美洲大蠊)分别进行药效和持效测定。结果:复配方药笔对德国小蠊的72h死亡率分别为100%、100%、100%、100%和90.33%;单配方药笔为100%、100%、100%、95.33%和81.67%。复方药笔对美洲大蠊72h死亡率为100%、100%、100%、95.67%和88.33%;单配方药笔为100%、97%、95.33%、91.80%和76.67%。结论:复配方药笔的药效优于单配方药笔,对德国小蠊的杀灭效果优于对美洲大蠊。

Abstract: Objective:Developing a new formula of cockroach-killing chalk by compounding to improve the killing efficacy and replace the single-formula products whose resistance was increasing. Methods: Contact method with thin-layer of the products. Two insecticides were tested. The products were painted on test boards with the dose of 15mg a.I./m2 and the boards were stored at room temperature for 24 hrs, 0.5 year, 1 year, 1.5 year and 2 years. Two strains of sensitive cockroach (Blattella germanica and Periplaneta americana) were used in the efficacy tests and stability tests. Results: The death rates in 72 hrs of B.germanica were 100.0,100.0,100.0,100.0 and 90.33 for the compound chalk; while the rates were 100.0,100.0,100.0,95.33 and 81.67 for the single-formula chalk. The death rates in 72 hrs of P.americana were 100.0,100.0,100.0,95.67 and 88.33; while the rates were 100.0,97,95.33,91.80 and 76.67. Conclusions: The compound chalk had better efficacy than the single-formula chalk and they both had better killing effects on B.germanica than that on P.americana.
