Abstract:
      Peanut is an important oil crop both for oil extraction and direct consumption in China. Aspergillus flavus and produced toxins are widely distributed at the stage of fields, storage, processing and circulation and has been recognized as main risk factors for the quality and safety of peanut. Aspergillus flavus and Aspergillus parasiticus reserved in soil serves as major sources of aflatoxin-producing fungi in peanut. Systematic study on the distribution of Aspergillus flavus and Aspergillus parasiticus in peanut fields is of great significance for early warning and ecological prevention and control of peanut aflatoxin. This paper summarizes the novel research results on the influencing factors and biogeographical distribution of Aspergillus flavus and Aspergillus parasiticus in peanut fields, and puts forward the existing problems and future directions of population biogeographical distribution of Aspergillus flavus and Aspergillus parasiticus in peanut fields.
