Abstract: Objective The present paper is about the killing effect test on a new redenticide for Kunming rat and SD mouse in laboratory.We also want to search the cause of death reasons by anatomized the dead mouse during the test.Methods We use the forced and continued way to feed the mice with rodenticide bait and observed the death rate.We used the common anatomy to get the data by eyes.Results The test showed that the new rodenticide could kill the Kunming mouse at 80% in 10 days and kill all SD mouse in 8 days.The chi-aquare test(χ²) showed that the noticeable difference existed between the Kunming and SD mouse.The anatomized dead mouse showed that it had intestinal blocking in gut,gas expanded in front of the intestinal blocking in gut,in intestinal membrane necrosis at the part of intestinal blocking and urine retention in bladder.Conclusion The new rodenticide had very good killing effect for mouse and rat in laboratory.Rats gave higher death rate than mice.The cause of death would be gas expanded made by the intestinal blocking,septicemia caused by necrosis happened at intestinal membrane and the urine retention at bladder.
