The aflatoxin type B and G producer was described in 2012 and was firstly reported from sputum, hospital air (Brazil), and soil (Colombia). Later, several survey studies reported the occurrence of this species in different foods and other agricultural commodities from several countries worldwide. This short communication reports on an old fungal strain (CBS 108.30), isolated from (grey sugarcane mealybug) from an Egyptian sugarcane field in (or before) 1930. This strain was initially identified as ; however, using the latest taxonomy schemes, the strain is, in fact, . These data and previous reports indicate that is strongly associated with sugarcane, and pre-harvest biocontrol approaches with non-toxigenic strains are likely to be more successful than those using non-toxigenic strains. Further studies on the association between and might shed light on the distribution (and aflatoxin contamination) of this species in sugarcane. Additionally, the interaction between , and sugarcane crop under different scenarios of climate change will be critical in order to get more insight into the host-pathogen interaction and host resistance and propose appropriate prevention strategies to decrease mycotoxin contamination and crop loss due to attack.
黄曲霉毒素B和G的产生菌于2012年被描述，首次报道于痰液、医院空气（巴西）和土壤（哥伦比亚）中。后来，多项调查研究报道了该菌种在全球多个国家不同食品和其他农产品中的存在情况。本简短通讯报道了一株于1930年（或之前）从埃及甘蔗田的灰粉蚧中分离得到的古老真菌菌株（CBS 108.30）。该菌株最初被鉴定为 ；然而，根据最新的分类学方案，该菌株实际上是 。这些数据和先前的报告表明， 与甘蔗密切相关，使用非产毒 菌株的收获前生物防治方法可能比使用非产毒 菌株的方法更成功。对 与 之间关联的进一步研究可能有助于了解该菌种在甘蔗中的分布（以及黄曲霉毒素污染情况）。此外，在不同气候变化情景下， 、 与甘蔗作物之间的相互作用对于更深入了解宿主 - 病原体相互作用和宿主抗性以及提出适当的预防策略以减少因 侵袭导致的霉菌毒素污染和作物损失至关重要。
