| 中文摘要:松树蜂Sirex noctilio是一种原产于欧洲各国、蒙古国、格鲁吉亚共和国和北非国家的松科林木蛀干害虫，属于国际上重大林业检疫性有害生物。其雌成虫产卵时向寄主树干注射毒液和共生真菌——网隙裂粉韧革菌Amylostereum areolatum。一般认为毒液能削弱寄主林木的防御能力，是导致寄主树木针叶出现变黄、枯萎等早期病理症状的主导因素，也是为共生真菌侵染创造条件的“条件作用剂”。毒液和共生真菌均不能单独致死林木，只有两者联合作用才会对寄主林木有致死性。该文综述了松树蜂毒液成分及性质、寄主松树对毒液的生理响应和松树蜂毒液作用的分子机制，并对植物激素诱导植物防御反应的研究前景进行展望，以期有助于促进毒-菌致寄主林木受害机制的深入研究，有助于基于植物激素免疫诱抗剂等新防控途径的开发。 |

| Abstract:The wood-boring woodwasp, Sirex noctilio, native to Europe countries, Mongolia, the Republic of Georgia, and North Africa countries, is a major international quarantine pest infesting pine trees. The female woodwasp injects venom and a symbiotic fungus Amylostereum areolatum into pine tree trunks when laying eggs. It is generally believed that the venom weakens the host trees’defense mechanisms, leading to pathological symptoms like yellowing and wilting of the needles, creating conditions favorable for A. areolatum infection. While venom and symbiotic fungi alone may not kill the host trees, their collaboration can be lethal. In this review, S. noctilio venom properties, physiological host tree responses, and molecular mechanisms were reviewed, and the prospects for future research were discussed. It offers valuable insights for improving our understanding of how the coordination between venom and symbiotic fungi impacts host trees, paving the way or the development of innovative measures, such as developing plant hormone immune inducers, for preventing and controlling this pest. |
