The English grain aphid and phytopathogen are wheat spike colonizers. "Synergistic" effects of the coexistence of and on the wheat spikes have been shown in agroecosystems. To develop genetic resistance in diverse wheat cultivars, an important question is how to discover wheat- interactions under influence. In recent decades, extensive studies have typically focused on the unraveling of more details on the relationship between wheat-aphids and wheat-pathogens that has greatly contributed to the understanding of these tripartite interactions at the ecological level. Based on the scientific production available, the working hypotheses were synthesized from the aspects of environmental nutrients, auxin production, hormone signals, and their potential roles related to the tripartite interaction -wheat-. In addition, this review highlights the relevance of preexposure to the herbivore to trigger the accumulation of mycotoxins, which stimulates the infection process of and epidemic of Fusarium head blight (FHB) in the agroecosystems.
英国谷物蚜虫和植物病原体都是小麦穗部的定殖者。在农业生态系统中，它们共存对小麦穗部具有“协同”效应。为了在不同小麦品种中培育遗传抗性，一个重要问题是如何在这种影响下发现小麦与它们的相互作用。近几十年来，广泛的研究通常集中在揭示小麦与蚜虫、小麦与病原体之间关系的更多细节上，这在很大程度上有助于在生态层面理解这些三方相互作用。基于现有的科研成果，从环境养分、生长素产生、激素信号及其与小麦三方相互作用相关的潜在作用等方面综合提出了工作假设。此外，本综述强调了预先接触植食性昆虫以触发霉菌毒素积累的相关性，这会刺激农业生态系统中病原体的感染过程和赤霉病的流行。
