摘要
利用组织切片对马铃薯瓢虫幼虫感染绿僵菌后的组织病理变化进行了初步观察。结果表明:在相对湿度95%与25℃的温湿度组合条件下,幼虫体表附着的孢子萌发后穿透体壁,在体腔内逐步形成菌丝体,进入体腔内的菌丝体,对寄主组织没有选择性。通常菌丝最初在侵染部位的血腔中生长,然后侵入邻近的脂肪体、肌肉,最后侵入消化道和丝腺等。
The pathological changes of Henosepilachna vigintioctomaculata infected by Metarhizium flavoiride were observed using tissue slice. The results showed that the fungi infected insect body mainly through cuticle under the condition of above 25℃ and 95 % relative humidity. Penetration process of M ahisopliae include adherence, germination, appressoria and penetration. Hypha in insect body showed no selection to host tissue. It grew in cutex, hemloyrnph lipoid and muscles, alimentary tract and malpighian tubule, etc. Pathologic change occurred on all tissue infected.
