Grain quality after harvest is influenced by a wide variety of abiotic and biotic factors and has been studied as a stored grain ecosystem. Important factors include grain and contaminant mould respiration, insects and mites, and the key environmental factors of water availability and temperature. Interactions between these factors influence the dominance of fungi, particularly mycotoxigenic species. Studies have shown that growth, mycotoxin production, competitiveness and niche occupation by mycotoxigenic species are influenced by the presence of other contaminant moulds and environmental factors. This has been demonstrated for both Fusarium culmorum and deoxynivalenol production, Aspergillus ochraceus/Penicillium verruscosum and ochratoxin production and Fusarium section Liseola and fumonisin production. Interactions between mycotoxigenic spoilage fungi and insects do occur but have not been studied thoroughly. Some insects disseminate mycotoxigenic species, others are known to use spoilage moulds as a food source, while others avoid certain fungal species. Thus, a more holistic ecological view is needed when considering management approaches to long-term-safe storage of cereal grains after harvest.

收获后真菌生态学：储粮中真菌生长和霉菌毒素积累的影响

收获后的谷物品质受多种非生物和生物因素的影响，并已作为储粮生态系统进行了研究。重要因素包括谷物和污染物的霉菌呼吸，昆虫和螨虫以及水的可利用性和温度的关键环境因素。这些因素之间的相互作用会影响真菌，尤其是致真菌毒素物种的优势。研究表明，产毒毒素种类的生长，霉菌毒素生产，竞争力和生态位占有受到其他污染物霉菌和环境因素的影响。 镰刀菌和脱氧雪腐烯醇的生产， 曲霉/疣状青霉 和曲霉毒素的生产 都证明了这 一点。 镰刀菌 科Liseola和伏马毒素的生产。确实发生了产毒毒素腐败真菌和昆虫之间的相互作用，但尚未进行深入研究。一些昆虫传播了致毒毒素物种，其他一些昆虫则利用腐败的霉菌作为食物来源，而其他一些昆虫则避免了某些真菌物种。因此，在考虑收获后长期安全保存谷物的管理方法时，需要更全面的生态观点。
