摘要
本试验利用玉米螟微孢子虫侵染亚洲玉米螟4龄幼虫,对患病幼虫的各组织器官进行解剖和显微镜观察,并对病变组织进行石蜡切片,复染后用光学显微镜观察并拍照。结果表明玉米螟幼虫的马氏管、丝腺、涎腺、神经、消化管为易感组织,感染后期可在玉米螟气管管壁细胞、中肠外纵肌等组织中也能发现微孢子虫,同时在实验过程中发现不能被感染的组织(细胞)有体壁的真皮细胞、体壁肌肉组织和脂肪组织,并查明了上述各组织中微孢子虫的侵染顺序和细胞的病理学变化。
Pathological change of tissues were observed, Ostrinia furnacalis (Guenée) larvae at stage of the 4th instar infected with Nosema furnacalis. The results showed that the Malpighian tubes,silk glands,salivary glands, nerve tissue and digestive tract of larvae were easy to be infected. At later infecting stage, spores were also found in tracheal cell, testis and its ancillary tissue, ovary and its ancillary tissue,longitudinal muscle of the midgut etc. However, epidermis and muscle tissue of body wall and fat body could be infected. The infection process and the histopathology were clear.
