| Abstract: | Objective To determine the current resistance of Blattella germanica to commonly used insecticides in Tongling, and provide evidence for better cockroaches control. Methods The jar method of insecticide exposure was employed. Resistance ratios were calculated as R = （KT50 of the test strain）/（ KT50 of the susceptible strains）. Results The KTso of field-collected population to dehamethrin,alpha-cypermethrin,permethrin, tetramethrin, and di- chlorovos were 17.50,5.66,15.69,13.95,14. 23 rain respectively, and the resistance ratios were 4.48,1.19,3.14, 4. 02,1.31 respectively. Conclusion The experiment shows that German cockroaches in Tongling city held some resistance to dcltamethrin,permethfin and tetramethrin. The highest is deltamethrin. The cock roaches don＇ t develop significant resistance to alpha-cypermethrin and diehlorovos. |
