Species of the genus Aspergillus are distributed throughout the world but are primarily represented
in subtropical and warm temperate climates. In warm, humid subtropical or tropical climates or even
in temperate climates in which the growing season is unusually hot and dry, species of the genus
Aspergillus can infect seeds in the fields. The movement of fungal species threatens food security and
creates global public concern worldwide. Climate change is altering the distribution, incidence and
intensity of plant pests that is moving north into more temperate zones of Europe. In recent years,
Serbia has been facing climate changes accompanied by a warming trend, which is a cause for concern.
A more frequent occurrence of Aspergillus species was observed in the years in which the weather
conditions were characterized by high temperatures, lack of precipitation and pronounced drought
conditions (2012, 2015, 2017). The intensive outbreaks of Aspergillus species were in 2012. In a...ddition
to the previously known species Aspergillus flavus, which was a storage pathogen, it also occurs in
field conditions. We discovered a new species of A. parasiticus in Serbia, for the first time. During the
2015 and 2017 we identified new species of the genus Aspergillus section Nigri. In order to adapt to
climate change, priority is given to the cultivation of drought-resistant maize hybrids. The introduced
challenges require additional climate change adaptation strategies, including various changes in
production systems, in order to maintain long-term productivity.
