本文报道了根据船舶上鼠粪的形状和大小,可判断其鼠种组成;从新鲜鼠粪的多寡和分布特征,可估计船舶鼠患程度的轻重。认为这种方法比粉迹法和ELTON夹日法测定鼠密度效果更可靠。
This paper reports that according to the shape and size of rat droppings on the ship, the rat species composition can be judged. From the perspective of the abundance and distribution of fresh rat droppings, the degree of rat challenge can be estimated. It is considered that this method is more reliable than the powder method and the ELTON pin method to determine the rat density effect.
