笔者应用双甲敌鼠胺盐（杀鼠新），以灌胃法进行小白鼠急性口服毒力测定，雄鼠ＬＤ５０为５８．８０ｍｇ／ｋｇ，雌鼠为４８．３７ｍｙ／ｋｇ．以玉米糁做诱饵，小白鼠对０．０５％和０．００５％杀鼠新诱饵的适口性均良好；与无毒饵比较，０．０５％毒饵的摄食系数为０．７４，０．００５％毒饵为０．８４；０．０５％杀鼠新毒饵与相同浓度敌鼠钠相比，摄食系数是１．０４．选用０．０５％杀鼠新玉米糁毒饵，在沈阳市郊某牛奶场进行局部现场灭鼠，投毒后６天累计盗食率为３７．５％（室内）和７０．５％（室外）：至３周时仅个别毒饵被盗食，此时鼠密度比灭鼠前降低８８．９％（室内）和８０．２％（室外）。
The application of double-nail enemies rat amine salt (new mice and mice) to gavage mice oral acute toxicity, male mice LD50 58.80mg / kg, female rats 48.37my / kg. The results showed that the palatability of the mice with 0.05% and 0.005% of the new baits was good with the bait of corn cob. Compared with the non-toxic bait, the feeding coefficient of the 0.05% bait was 0.74,0.005% The bait was 0.84; the coefficient of feed intake was 0.05% compared with the same concentration of sodium pentamers at 0.05%. The rats were killed on the local field in a dairy farm in the suburbs of Shenyang City. The accumulated rate of stolen food after 6 days of poisoning was 37.5% (indoor) and 70.5% (outdoor): At week 3, only individual bait was stolen, at which time the density of the rats was reduced by 88.9% (indoor) and 80.2% (outdoor) than before decontamination.
