摘　　要： 为了解臭鼩的生物学特性,2011年7月至2012年12月,以花生为诱饵,采用铗日法捕获了115只臭鼩,对其消化系统形态结构及食性进行分析。结果显示,臭鼩食道平均长约5.4 cm,重约0.21 g,体积约0.18 mL;满胃(含胃内容物)平均长约3.15 cm,重约1.83 g,体积约2.06 mL;空胃(洗去胃内容物)平均重约0.91 g,体积约0.94mL,雌雄间稍有差异。肠的长度平均为51.40 cm,重约3.12 g,体积约3.75 mL。胰腺和肝脏分别重约0.48 g和2.29 g,体积约为0.54 mL和2.04 mL,两种主要消化腺也是雄性稍大于雌性。对所有样品胃容物进行检验后,发现臭鼩主要取食动物性食物,植物性食物次之,其中动物性食物约占70.52%,植物性食物占29.48%。臭鼩有一定危害,采取投毒法不能有效降低其种群数量,无法达到理想的防治效果。 From July 2011 to December 2012, 115 Suncus murinus were catched to understand their biological characteristics with method of mouse-trap-day in Yulin, Guangxi. Study on digestive system and feeding habit of this species was carried out. Result showed that, the length, weight and volume of esophagus were 5.4 cm, 0.21 g and 0.18 mL; these data of stomach with food were 3.15 cm, 1.83 g and 2.06 mL; the weight and volume of stomach without food were 1.83 g and 2.06 mL; the length, weight and volume of intestine were 51.40 cm, 3.12 g and 3.75 mL; the weight of pancreas and liver were 0.48 g and 2.29 g; the volume of pancreas and liver were 0.54 mL and 2.04 mL. After the analysis of feeding habit, the result showed that musk shrew was omnivorous, mainly fed on animal food, the volume rate of animal food reached 70.52%. S.murinus has certain hazards, poison method can not effectively reduce the population quantity, is unable to achieve good control effect.
