Genes and genetic mechanisms contributing to fall armyworm resistance in maize

The Plant Genome, 2023
Maize (Zea mays L.) is a crop of major economic and food security importance globally. The fall armyworm (FAW), Spodoptera frugiperda, can devastate entire maize crops, especially in countries or markets that do not allow the use of transgenic crops ...

Forecasting the global extent of invasion of the cereal pest Spodoptera frugiperda, the fall armyworm

NeoBiota, 2018
Fall armyworm, Spodoptera frugiperda, is a crop pest native to the Americas, which has invaded and spread throughout sub-Saharan Africa within two years. Recent estimates of 20–50% maize yield loss in Africa suggest severe impact on livelihoods.
