摘　　要：研究了壮蚕 (4～ 5龄 )微孢子虫感染与微粒子病显微镜判别时期的关系。结果表明 ,在一定范围内 ,显微镜检别出微粒子病的时期随微孢子虫接种剂量的增大而提早 ,并且 3个取样部位从先到后镜检出的顺序分别为病蚕中肠、病蚕整体、病蚕粪便。This paper studied on the effects of the dosages of Nosema bombycis on grown stage silkworms (4-5 instars). Specimens were detected by microscope for the diagnostic time of pebrine disease in silkworm. The results showed that the detected time of spores in midgut, whole body and faeces of the infected silkworm by microscope advanced with the increase of N.bombycis dosage. Furthermore,spores in midgut were detected earlier than those in whole body and faeces.
