Abstract

Ceratocystis fimbriata plays a significant role in the initiation of the tree decline disease in mango (Mangifera indica L.), which can kill the plant. The C. fimbriata infection is linked with the presence of the beetle Hypocryphalus mangiferae (Curculionidae: Scolytinae). However, it is unknown how H. mangiferae aids in the transport of the fungus between mango trees. The present study aimed to investigate the external surface of H. mangiferae adults using scanning electron microscopy to detect signs of the fungus. Fungal structures were found to adhere to the mandible and elytra of H. mangiferae, implying that H. mangiferae, while moving between mango trees, may spread the fungus through contact. Our findings may be useful in developing strategies to minimize the economic impact caused by diseases through the control of beetles in mango orchards.

摘要

Ceratocystis fimbriata在芒果 ( Mangifera indica L.)的树木衰退病的发生中起重要作用，该病可以杀死植物。所述C.黑斑病感染与的甲虫存在链接Hypocryphalus芒果（：Scolytinae象虫科）。然而，它是未知如何H.芒果中的芒果树之间的真菌的运输辅助工具。本研究旨在使用扫描电子显微镜检查芒果成虫的外表面以检测真菌的迹象。发现真菌结构，坚持到下颌骨和鞘翅H.芒果，暗示H.芒果，在芒果树之间移动时，可能会通过接触传播真菌。我们的研究结果可能有助于制定策略，通过控制芒果园中的甲虫来最大限度地减少疾病造成的经济影响。
