Abstract: Objective To investigate the insecticidal effect of three commercially available aerosols on Cimex lectularius and Attagenus unicolor japonicus, and to investigate the sensitivity of these two types of sanitary pests to different insecticidal aerosols. Methods According to the national standard GB/T 13917.2-2009, the cylinder method was used to determine the knockdown rate of C. lectularius and A. unicolor japonicus after 20-min exposure to the aerosols, and the mortality rate at 48 h and 72 h were observed. The Chi-square test was used to compare the 20-min knockdown rate and mortality rate between different groups. Results In the killing test to A. unicolor japonicus, the 20-min knockdown rate, and the mortality rate at 48 h and 72 h of A. unicolor japonicus were all 100% after exposure to the three commercially available aerosols; in the killing test to C. lectularius, the knockdown rates of C. lectularius were 100%, 98.33%, and 90.00%, respectively, after 20-min exposure to No. 1, No. 2, and No.3 aerosols, but the mortality rates of C. lectularius were 100% at 48 h and 72 h after exposure to the three aerosols. There was no significant difference in 20-min knockdown rate between different groups (χ2=3.000, P>0.05). Conclusion The killing effect of three commercially available aerosols on C. lectularius and A. unicolor japonicus measured according to the method of the national standard GB/T 13917.2-2009 showed that relatively high knockdown and killing rates can be achieved.

摘要: 目的 研究3种市售杀虫气雾剂对温带臭虫及黑毛皮蠹的杀灭效果,了解2种卫生害虫对不同成分杀虫气雾剂的敏感性。方法 根据国标GB/T 13917.2-2009,用圆筒法测定杀虫气雾剂对温带臭虫和黑毛皮蠹的20 min击倒率,并观察48和72 h死亡率。采用χ2检验分析不同组别间20 min击倒率和死亡率的差异。结果 对黑毛皮蠹的杀灭实验中,3种市售杀虫气雾剂对黑毛皮蠹的20 min击倒率、48和72 h死亡率均为100%;在杀灭实验中,1、2和3号气雾剂对温带臭虫的20 min击倒率分别为100%、98.33%和90.00%,但3种杀虫气雾剂对温带臭虫48和72 h死亡率均为100%。不同组别间20 min击倒率差异无统计学意义(χ2=3.000,P>0.05)。结论 根据国标GB/T 13917.2-2009的方法测试的3种市售杀虫气雾剂对温带臭虫及黑毛皮蠹的杀灭效果,能够达到较高的击倒率和杀灭率。
