将昆虫病原真菌作为生物防治剂纳入害虫综合治理（IPM）计划无疑是非常有效的。这些真菌病原体如球孢白僵菌（Beauveria bassiana）和金龟子绿僵菌（Metarhizium anisopliae）作为内生菌存在于植物中并保护其定殖宿主植物免受主要草食性害虫侵害的能力已被广泛报道。除了传统上归因于真菌内生菌的害虫管理的唯一作用之外，最近的研究结果提供了植物产量促进剂、土壤养分分配剂、非生物胁迫和植物耐旱性增强剂的其他可能功能的证据。然而，关于真菌内生菌对定殖植物的这些额外重要影响的报道仍然很少。本文综述了植物内生真菌对寄主植物及其主要害虫的各种有益作用，以及一些相对未知的负面影响。我们还强调了我们的研究结果在进一步提高真菌内生菌作为优化作物生产的害虫管理计划的一个组成部分的接受度方面的前景。
The incorporation of entomopathogenic fungi as biocontrol agents into Integrated Pest Management (IPM) programs without doubt, has been highly effective. The ability of these fungal pathogens such as Beauveria bassiana and Metarhizium anisopliae to exist as endophytes in plants and protect their colonized host plants against the primary herbivore pests has widely been reported. Aside this sole role of pest management that has been traditionally ascribed to fungal endophytes, recent findings provided evidence of other possible functions as plant yield promoter, soil nutrient distributor, abiotic stress and drought tolerance enhancer in plants. However, reports on these additional important effects of fungal endophytes on the colonized plants remain scanty. In this review, we discussed the various beneficial effects of endophytic fungi on the host plants and their primary herbivore pests; as well as some negative effects that are relatively unknown. We also highlighted the prospects of our findings in further increasing the acceptance of fungal endophytes as an integral part of pest management programs for optimized crop production.
