对辽宁省化工研究院生产的“杀鼠新”用灌胃法做小白鼠急性口服毒力测定,雄鼠:LD_(50)=58.80mg/kg;雌鼠LD_(50)=48.37mg/kg。周玉米糁做为诱饵,观察小白鼠对0.05％和0.005％杀鼠新毒饵的适口性均为良好;同无毒饵比较,0.05％毒饵的摄食系数0.74,0.005％毒饵为0.84;0.05％杀鼠新毒饵与同浓度的敌鼠钠毒饵相比,摄食系数是1.04。用0.05％杀鼠新玉米糁,在沈阳市郊某牛奶场做局部现场灭鼠,投毒后6天,鼠类对毒饵盗食率高达37.5％(室内)和70.5％(室外),投毒后3周时,仅个别的毒饵被盗食,此时鼠密度比灭鼠前降低88.9％(室内)和80.2％(室外)。
The acute oral toxicity of mice was determined by the method of gavage with the method of “killing rats” produced by Liaoning Institute of Chemical Industry. The male mice: LD_ (50) = 58.80mg / kg; female mice LD_ (50) = 48.37mg / kg . Compared with the non-toxic bait, 0.05% bait had 0.74,0.005% bait and 0.84% bait, while 0.05% The new bait with the same concentration of the anti-rat sodium bait compared to food intake coefficient is 1.04. Rats were killed on the spot in a dairy farm in the suburbs of Shenyang City with 0.05% of the rats. After 6 days of poisoning, the rodents were 37.5% (indoor) and 70.5% (outdoor) At week 3, only individual poison bait was stolen, at which time the density of the rats was reduced by 88.9% (indoor) and 80.2% (outdoors) than before decontamination.
