摘　　要：以夏芳蚕品种为材料 ,对其不同蚕期、不同龄期间肠道好氧微生物种群构成及其变化情况进行了系统的研究。结果表明 :春蚕肠道好氧菌数量较多 ,以肠杆菌、微球菌科菌和芽胞杆菌科菌为主 ;秋蚕肠道好氧菌只有少量微球菌科菌和芽胞杆菌科菌存在 ;人工饲料育肠道好氧菌数量较少 。A systematic study was made of the composition and fluctuation of obligate aerobes in the intestines of Xia Fang race of silkworm in different larval periods and stadia.Spring silkworms were shown to have more obligate aerobes in their intestines,being composed mainly of the families of Enterobacteria,Micrococcus and Bacillus.The intestines of autumn silkworms contained only a few aerobes of Micrococcus and Bacillus.The number of aerobes in the intestines of the silkworms reared with artificial fodder was small,consisting mainly of Bacillus bacteria.
