Abstract: Objective To know the effects of mall anti bearing bait on anti procreate and controlling population size and to study the standard methods of anti bearing bait effect analysis in field.Methods "Beiao" bait and no "beiao" were selected to evaluate the feeding acceptability of SD rats in laboratory by select fooding method;after putting "beiao" in field for three and six monthes,the results for controlling rats by trap were recorded respectively;rats procreation and rate of infancy and manhood of catching rats from three fields("beiao" bait,Anti Cruor bait and naturalness) were analized by anatomised.Results(1) In laboratory,the coefficient of select food for SD rats was 0.45.(2)The rate of fetch was 30.0% outdoor,and 40.67% indoor.(3) After applied "beiao" for three and six monthes respectively,the RPI was 38.44 and 36.44 for treatment and CK(naturalness) respectively;while compareed with anti cruor,the RPI was 51.06 and 63.39.(4) The rate procreation of Apodemus agrarius from three areas("beiao" bait、Anti Cruor bait and naturalness)was different from each other,which were 0、22.00% 、27.78% respectively.(5)The rate of infancy and manhood was different from three areas.Conclusion The results from laboratory and fields showed that "beiao" baits has coefficient of select food and after put in fields half year,and has value in controlling rats compareing with anti cruor bait and naturalness.It may be used to control rats.The standard and methods on anti bearing bait has established that has operated.
