Abstract: Objective:Comparing the influences of test methods on their results of KT₅₀ and 24 h death rate of mosquito in order to explore the proper way to evaluate mosquito incense products.Methods:Simulating field test and the standard test for indoor insecticidal efficacy were adopted according to the test methods and evaluating standards of GB13917and GB/T17322.Results:Amoung mosquito-repellent products,incense coils had better insecticidal efficacy in simulating field test than in the indoor insecticidal efficacy test(χ²=18.66,P<0.05) while electric mosquito-repellent mat and electric mosquito-repellent liquid had no significant differences(χ²=0.32,P>0.05).Conclusion:Amoung mosquito-repellent products,incense coils had better insecticdal efficacy in simulating field test than in the indoor insecticidal efficacy test while electric mosquito-repellent mat and liquid had no significant differences.The two methods complemented mutually.Adoption of them meantime in tests of mosquito-repellent products can correct or reduce experimental error.
