Toxicity of Ethyl Formate on Adults of Liposcelis entomophila

摘要

The fumigation activities of ethyl formate （EtF) against adults of Liposcelis entomophila (Enderlein) were researched by the sealedjar fumigation method under the conditions of different EtF dosages, temperatures and exposure times in laboratory. The results indicated EtF dosage, temperature and exposure time affected the fumigation efficacy significantly. EtF showed a high fumigation activity within short exposure time and EtF performed better at relatively low temperature than at relatively high temperature. At 20℃,25℃ and 30℃ after 24 h fumigation,the LC50 values were 7. 769,8. 964 and 9. 900 μL/L, respectively.
