The storage mite Tyrophagus putrescentiae (Schrank) (Acari: Acaridae) is one of the most important pests of stored foods (cheese, corn, oats, wheat, soy etc.), and is found in heavy infestations. Mites can infest food that are stored under unsatisfactory sanitary conditions, which may also provide conditions for fungi growth, which indicates mite-fungus association. However, little is known about the influence of T. putrescentiae on mycotoxins production under different stored products over time. The main objective of the present study was to identify the fungal species present in oats, corn, and wheat flour associated with T. putrescentiae infestations, and evaluate mycotoxin production before and after six months storage with these infestations. Wheat, corn and oat grain samples were compared, and each crop was stored in six containers infested by T. putrescentiae. Three remaining containers were stored under the same temperature and humidity conditions without introducing the mites, which worked as control. We obtained 55 fungi isolates, and the majority were identified with 99% or 100% of identity and ≥97% of coverage with type strains of each fungal species. Mycotoxin concentrations analyzed from corn flour stored for six months decreased with and without T. putrescentiae (p < 0.05). Regarding mycotoxin concentration with T. putrescentiae, aflatoxin increased in oats (p < 0.05) while zearalenone decreased in wheat (p < 0.05). Our findings proved that T. putrescentiae could significantly induce mycotoxin production in stored products evaluated for six months.

贮藏螨Tyrophagus putrescentiae (Schrank) (Acari: Acaridae) 是贮藏食品（奶酪、玉米、燕麦、小麦、大豆等）中最重要的害虫之一，在大量侵染中发现。螨虫可以感染在卫生条件不令人满意的情况下储存的食物，这也可能为真菌的生长提供条件，这表明螨与真菌的关联。然而，随着时间的推移，关于腐烂木霉对不同储存产品下霉菌毒素产生的影响知之甚少。本研究的主要目的是确定燕麦、玉米和小麦粉中与腐烂霉病相关的真菌种类侵染，并评估在这些侵染情况下储存 6 个月之前和之后的霉菌毒素产量。对小麦、玉米和燕麦谷物样品进行了比较，每种作物都储存在受腐烂霉感染的六个容器中。剩余的三个容器在相同的温度和湿度条件下储存，不引入螨虫，作为对照。我们获得了 55 个真菌分离株，大多数被鉴定为具有 99% 或 100% 的同一性，并且与每种真菌物种的类型菌株的覆盖率≥97%。从储存六个月的玉米粉中分析的霉菌毒素浓度在有和没有腐烂 T. 的情况下均降低（p < 0.05）。关于腐烂发霉的霉菌毒素浓度，燕麦中的黄曲霉毒素增加（p < 0.05），而小麦中的玉米赤霉烯酮减少（p < 0.05）。我们的研究结果证明，腐烂木霉可以显着诱导已评估六个月的储存产品中霉菌毒素的产生。
