褐家鼠对单种和组合引诱剂的选择性试验

选用糖精、食盐、食醋、白酒４种引诱剂，单一品种或几种组合制成敌鼠钠盐大米毒饵，对褐家鼠分别进行了实验室选择性试验。结果表明，褐家鼠对单种引诱剂毒饵消耗最多的是加酒毒饵，其次为加糖精毒饵，与纯毒饵摄食系数相比差异极为显著（Ｐ＜０．０１），而加盐和加醋毒饵的摄食系数小于纯毒饵；组合引诱剂毒饵以糖、盐、酒毒饵对褐家鼠的接受性最好，其它３种组合未能增加诱力。认为咸味对褐家鼠的引诱力不大，酸味反而降低褐家鼠对毒饵的适口性。

Selective Tests of Rattus norvegicus on the Single or Composite Attractants

With saccharin,salt,vinegar and wine for the lure reagent,single or several kinds of them were used in making the rice poison baits of diphacine-Na,and Rattus norvegicus were used in the selective tests.The results were as follows.The consumption of R.n.on the poison baits of the single type attractant was the most with wine,seeond with saccharin.There were significant differencs(P<0.01),comparing with the food breeding index of the pure rice poison bait.But the food breeding indexes of the poison baits with sodium chloride or vinegar were less than that of the pure rice poison bait.Of the composite attractants,the poison bait with saccharine, salt and wine obtained the best acceptability,and other three kinds of composite attractants could not increase the consumption.It also showed that the lure of the salty was not very strong and the acidity could decrease the taste of the poison bait for R.n.
