摘要
研究了显微镜检出蚕微粒子病的时期与微孢子虫感染剂量、感染蚕龄和所取样本的关系⒚结果表明,蚁蚕和2 龄起蚕感染高剂量微孢子虫时,能在当龄镜检出孢子,感染低剂量微孢子虫时,可在次龄或以后镜检出孢子⒚从感染蚕中肠、粪便和蚕整体中镜检出孢子的时期,随微孢子虫感染剂量增大和感染蚕龄降低而提早,并且镜检出的时期从先到后分别为病蚕中肠。
The relationship between the infective stage and dosage of Nosema bombycis and the specimen for detection on the diagnostic time of pebrine disease of silkworm. The results showed that the spores can be detected from the infected silkworm larvae body by microscope in infected instar when newly hatched larvea and newly first exuviated larvae were inoculated with high dosage of N.bombycis . And the detective time of spores in midgut, faeces and total body of N.bombycis infected silkworm larvae by microscope were earlier with larger dosage and smaller silkworm instar of infection by N.bombycis . Further, the detective time of spores in midgut as sample was earlier than these in total body and faeces as sample. The results are of practical value to the control of pebrine disease of silkworm in silkworm eggs production.
