摘　　要：对感染绿僵菌的椰心叶甲幼虫进行组织切片观察,结果表明,绿僵菌可通过体壁及气门侵染虫体,其中经体壁侵染是主要的方式。接菌后第1天即可在血腔中发现菌丝段,感染早期可见大量血细胞在皮细胞层下聚集,血腔中的菌丝段随血液循环到达各组织器官,并可逐渐侵入脂肪体、肌肉、食道、气管、唾腺等组织,被侵染组织器官的结构均遭到不同程度的破坏。A histopathological study on Brontispa longissima larvae infected by Metarhizium anisopliae showed that the fungi infected body mainly by penetrating the cutuile,however,it also could infected the body throug spiracle.The mycelium could be found in haemocoel 24 h after infected,and a large number of haemocytes congregated just beneath the epidermis.Invasion of the hyphae to host tissues showed no selection,and the pathological changes occurred on all infected tissues and organs,including fat body,muscle,mid gut,salivary gland and trachea.
