从害鼠的捕食性天敌、寄生性病原微生物、生物毒素和遗传控制等 4个方面论述了林区鼠害生物控制措施的研究现状 ,提出了在天敌动物的利用过程中要注意招引、保护和饲养天敌以及在应用寄生性病原微生物防治害鼠时 ,病原菌要对人畜无害 ,对害鼠的毒力要强而稳定 ,对多种害鼠均有致病力 ,同时不与其它微生物产生交叉免疫等 From the four aspects of predatory natural enemies, parasitic pathogenic microorganisms, biological toxins and genetic control of rodents, the research status of rodent biological control measures in forest area was discussed. In the process of utilization of natural enemy animals, attention should be paid to attract, protect and Feeding enemies and parasitic pathogens in the prevention and treatment of rodent pathogens, pathogenic bacteria should be harmless to humans and animals, the virulence of rats to be strong and stable, have a variety of pathogenic rats virulence, while not cross-immunization with other microorganisms Wait
