摘要: 士的宁(strychnine)是从番木鳖(Shrychox nuxvomica)种子提得的一种生物碱。作为兴奋剂用于医疗方面和作为生化试剂使用,但作为杀鼠剂用来防治害鼠,国内尚未见有报道。在国外,士的宁被用于防治危害森林草地、作物地内的地下鼠和其它有害哺乳动物(Marsh,1978;Barnes,1980;Crouch,1980;Anthony,1984)。作者于1983—1984年期间针对草原主要害鼠之一——高原鼢鼠(Myospalax baileyi)进行了灭杀试验研究。

Abstract: This work was carried out on alpine meadow of Zeku and Menyuan Country of Qinghai Province in September, 1983,and in June,July, 1984.Strychnine was used to kill the plateau zokor (Myospalax baileyi) in laboratory and field trials.The LD50 is 23.12 mg/kg for the white rat and 15.65mg/kg for the zokor respectively.The poisoned rodents die after 5 minutes, but dead peak appears within 10-40 minutes.A fox and six white rats were fed with the dead rats poisoned by strychnine and secondary poisoning had not been observed.In field tests,using three different kinds of baits with 0.6% strychnine all poisoned the zokor effectively,among them,the potato poisoning bait was the best,with an efficiency of 67.83%.
