摘要
１９９２～１９９４年在中粳稻区研究了黑线姬鼠发生动态和春秋季防治指标。结果表明，４～５月、９～１０月为繁殖高峰；５～６月和１０～１１月为数量高峰。水稻不同生育期害鼠百夹日捕获率（Ｘ）与产量损失率（Ｙ）呈显著正相关，早春为防治适期，在现有生产水平下，防治指标（百夹日捕获率）为３％，水稻主害期控制指标为６％～７％。
Occurence and population dynamics and control indics of Apodemus agrarius in nonglutions rice rigion were studiesin spring and autumn in 1992～1994.The results showed that reproductive and number peaks of the population were in April toMay and September to October,May to Jun and October to November,respectively.Capture rate(x)/100 rat clip was signifi-cantly posltive correlation with yield loss rate of rice(Y).The better stage of control of the rat was in early spring. Under cur-rent producting level,control indices were determined as 3 per cent of capture rate(100 rat clip)and 6～7 per cent during maindamage stage of rice.
