鼠类不育控制的生态学基础

（１）不育控制是与传统的单一化学灭杀截然不同的鼠害防治策略，它着重于降低种群生育率来达到控制鼠类数量的目的。（２）传统不育控制在不育个体对生育个体的竞争性繁殖干扰方面注意不够，低估了不育控制的潜力。（３）本文依据生态学原理，经过数学推理和分析后认为，即使在不考虑竞争性繁殖干扰的情况下，不育控制基本上可以达到同样水平单纯灭杀的控制效果；若再考虑到不育个体的竞争性繁殖干扰作用，不育控制的实际效果将明显

THE ECOLOGICAL FUNDAMENTALS OF RODENT CONTROL BY CONTRACEPTION

The contraception control is a different strategy of rodent management from thetraditional culling which emphasize on reducing the birth rate instead of increasing mor-tality of rodent population. 2.In the strategy of traditional contraception control,the competitively reproduc-tive interference by sterile individuals to reproductive ones was ignored and thus the po-tentiality of contraception in rodent control was less estimated. 3.After theoretical analysis we believe contraception is as effective as traditionalculling in controlling rodents even without consideration of competitively reproductiveinterference by sterile individtials. If such interference is taken into account,contracep-tion may be much better than culling. 4.A new strategy of using contraception was suggested in this paper.It focused onthe combination between the contraception control and culling,In this way, The newstrategy owned both the advantages of contraception control and culling,i.e, crash ro-dent population quickly and keep them at a very low level for a long time.
