Researchers from Lorestan University confirmed fall armyworm in Lorestan province. They used genetic tests on larvae taken from maizefields, but data on crop damage in Lorestan are not yet available.
The pest feeds on more than 80 crops and is most likely to attack maize, where it can cut yields by up to 60 per cent, according to CABI. Scientists say the ongoing war in the Middle East could delay responses because maritime and air travel in the Gulf may be disrupted.
Experts advise early scouting and use of local biopesticides such as Bacillus thuringiensis and neem. They also stress farmer training and quick action to contain outbreaks. The FAO called the concern regional but not at panic levels.
