多种真菌可在玉米体内竞争性定植，并产生多种霉菌毒素，其中主要是伏马菌素B（FBs），会对玉米安全性和质量产生负面影响。本研究旨在调查欧洲玉米螟杀虫剂应用对2009-2015年在意大利西北部人们食用的玉米中“新出现的”与其他已知（已立法的）的真菌毒素和其他真菌代谢产物的污染的影响。研究结果表明，使用杀虫剂是温带地区对食品玉米使用的最常见的FBs控制措施，从而也使李瑟组镰孢霉菌产生的其他霉菌毒素显著减少。然而，这种做法通常不能降低色变组镰刀菌和粉红镰刀菌真菌毒素的含量。在有利于上述镰刀菌产生的脱氧雪腐镰刀菌烯醇和其他代谢物的环境和农艺条件下，使用杀虫剂处理甚至会增加它们的污染。
外文摘要：
Maize can be competitively colonized by several fungi that are capable of producing a variety of mycotoxins, mainly fumonisins B (FBs), with a negative impact on maize safety and quality.
The aim of this study was to investigate the impact of the insecticide application against European Corn Borer on the contamination of "emerging" mycotoxins and other fungal metabolites co-occurring with the legislated ones in maize for human consumption in North-West Italy from 2009 to 2015.
The insecticide application on average significantly increased the yield by 5%, and significantly reduced the ECB incidence and severity and the fungal ear rot incidence and severity compared to the untreated control.
Overall, 25 Fusarium mycotoxins and metabolites were detected. The results underline that the use of the insecticide, the most common FBs control practice in temperate areas on food maize, also resulted in significant reductions of other mycotoxins produced by Fusarium spp. of the Liseola section. However, this practice was not generally able to reduce the contents of Fusarium spp. section Discolor and Roseum mycotoxins. In environmental and agronomic conditions that favor deoxynivalenol and other metabolites produced by the previous mentioned Fusarium spp., the insecticide treatment could even increase their contamination.外文关键词：Maize；Fumonisins；Emerging mycotoxins；Fusarium；Insecticide；European corn borer
