Scientists have detected fall armyworm in western Iran’s Lorestan province. A study in the June issue of Asia Pacific Entomology reports genetic testing of larvae collected in maizefields and confirms the pest’s presence. Local data on crop damage in Lorestan are not yet available.
Fall armyworm feeds on more than 80 crops and is most damaging to maize, where yields can fall sharply, the report says. The pest is native to tropical Latin America and has already spread across Africa, Asia and Australia. Experts warn that the ongoing war in the Middle East could make responses harder by disrupting travel and supply chains through the Strait of Hormuz.
Researchers and CABI advisers recommend early scouting, biocontrol and local biopesticides such as Bacillus thuringiensis and neem extracts. They stress training for farmers and extension workers to improve surveillance and rapid response. The FAO described the situation as regional concern but not at panic levels.
