[目的]为研究绿僵菌侵染椰心叶甲的部位、侵染的过程以及防治措施提供参考依据。[方法]利用扫描电子显微镜对采自大田、自然感染绿僵菌的椰心叶甲虫体表面进行扫描观察。[结果]椰心叶甲体表面自然感染绿僵菌的部位不仅在腹部与前胸的节间膜处,在腹部的两侧以及腹末节腹板的尾部,都观察到了大量已形成与感染密切相关的结构物质——侵染钉以及菌丝、孢子等。[结论]绿僵菌对椰心叶甲侵染时在营养物质、pH值、温湿度等不同环境条件下,椰心叶甲虫体表面被破坏的程度有所不同。
[Objective] The research aimed to provide references for studying the site of infection of Metarhizium anisopliae, infection process and control measures. [Method] Scanning electron microscope (SEM) was used to observe the body surface of Coccinella septempunctata which was collected from field and naturally infected with Metarhizium anisopliae. [Result] The site of naturally infected Metarhizium anisopliae on the surface of coconut leaf was observed not only in the intima of the abdomen and anterior chest, but also on both sides of the abdomen and the tail of the web of the abdomen. A large number of structures that had been closely related to infection were observed Substance - Infected nails and mycelium, spores and so on. [Conclusion] Metarhizium anisopliae had different degrees of damage on the surface of Beetle under the different environmental conditions such as nutrients, pH value, temperature and humidity.
