【摘要】 据调查，浙江省常见的农田鼠害有１３种，黑线姬鼠为优势种。每年春、秋季节害鼠大量繁殖，６月和１１月各出现一次种群数量高峰。水稻鼠害株属聚集型分布，主要为核心分布，部分田块呈负二项分布。经鼠害种群密度与稻、麦等作物不同生育期产量损失的相关回归分析，求得经济允许害鼠密度为：大小麦穗期２．７～４．３％，早稻穗期４．６～６．７％，晚稻穗期６．９～８．４％，晚稻分蘖期１５．８～２０．６％。农田鼠害的测报可采取查害鼠密度、优势种群、年龄结构和发生规律，定灭鼠范围、主攻对象、灭鼠次数及防治适期。在害鼠密度较高的情况下，以药治为主，辅以其它措施。溴敌隆、敌鼠钠盐、杀鼠迷等有良好的杀灭效果，可制成毒饵投放更多还原

【Abstract】 Thirteen species of field mouse were observed, Apodemus agrarius Pallas among them was dominant species Most damage of field mouse occured in spring (June) and deep autumn (November) Rice plants injured by mouse presented a gregarious distribution, mainly kernel distribution, rice plants in partial fields were negative binomial distribution By regressive analyses on yield losses in different development stage of rice, wheat related with mouse population density, EILs presented here were: 27-43% in heading stage of barley and wheat, 46-67% in heading stage of early rice, 69-84% in heading stage of lat rice, 158-206% in tillering stage of late rice Mouse damage prediction can be made out of investigating mouse density, dominant species, age conponents, determining control range, species and timing Mainly chemicals must be used in higher density of mouse populations while using other measures assistance subsidiary, other measures bromadiolone, diphacinone and coumatetralyl were fitable for making toxic daits更多还原
