2025 Northland Future Forages: Pest Susceptibility of Key Forage Species ReportSpodoptera litura (tropical armyworm)
report
posted on 2025-06-03, 21:28 authored by Joanne JensenJoanne Jensen, Deb HackellDeb Hackell, Sofia Orre-GordonThis report is to evaluate insect pest susceptibility of key pasture species. We assessed forage susceptibility to feeding by the polyphagous feeder, Spodoptera litura (commonly called tropical armyworm). Spodoptera litura is a serious pest in tropical/subtropical regions overseas but is considered a sleeper pest in New Zealand as its impacts are currently constrained by NZ’s cooler temperate conditions. Given the impact of S. litura in tropical climates, it is likely to become more damaging to Northland forages under climate change.
This report evaluates S. litura forage preferences, feeding damage and survival on key pasture species.
