Abstract
Objective To survey the effect of the propoxur against German cockroach. Methods The method of chemical smeared into the jam bottle was used in this study. Results The KT 50 average of the propoxur to the susceptible German cockroach was 13.86 min, and the KT 50 of that to eight field strains was from 11.25 to 38.02 min, and the KT 50 of that to the resistant strain against permethrin was from 16.06 to 23.37 min. The death ratios were all 100% after 72 hr. The death ratios on the spot were still 90.58% after treating for 4 d. Conclusion The effect of the propoxur to field German cockroach was general knock-down, and the resistant strain against permethrin hadn't formed alternating resistance,while the effect of propoxur controlling cockroaches in ship was better after it was soluted into water.
