【摘要】 为了明确褐家鼠食量与其对干玉米造成的实际损失量之间的关系,以干玉米籽粒为诱饵,在室内对褐家鼠进行无选择性取食试验。结果表明:褐家鼠取食干玉米的平均食损比为0.23±0.09,即平均每只褐家鼠在盗食干玉米时可以造成其食量4倍左右的损失。更多还原

【Abstract】 In order to find out the relationship between the maize intake of Rattus norvegicus and the real loss of maize,taking dry maize grain as bait,nonselective intake tests on Rattus norvegicus were conducted by feeding maize in laboratory.The results showed that the average feed-loss ratio was 0.23±0.09,which indicated that the loss caused by each Rattus norvegicus was almost four times than intake.更多还原
