Abstract: 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 differencsP<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.
