摘　　要：目的通过生物测试，观察天然除虫菊素杀虫气雾剂对蟑螂的药效。方法按GB13917．2—92和GB／T17322．2—1998规定进行。结果实验室按0．5～1．0g/筒剂量处理后对德国小蠊和美洲大蠊的KT50为1．02-8．06min，72h死亡率为100％；模拟现场按2．5g／m^2和5．0g／m^2剂量处理后，1h击倒率均为100％，72h死亡率为100％。结论天然除虫菊素杀虫气雾剂具有安全，高效等特点，值得推广应用。Objective To observe the efficacy of pyrethrins aerosol against cockroaches by bioassay. Methods According to GB13917.2 -92 and GB/T17322.2 - 1998. Results In lab, after spraying aerosol with dose of 0. 5 -1.0 g per barrel against Blattella germanica and Periplaneta americana. The KT50 was 1.01 - 8.06 minutes. The mortality of 72 hours was 100%. While in mimic field, after spraying aerosol with dose of 2.5 and 5.0 g/m^2 , the killing rate of one hour was 100%. The mortality of 72 h was 100%. Conclusion Pyrethrins aerosol was safe for use and had high efficacy. It should be generalized.
