Detection
Moths attracted to pheromones traps, larvae hidden in foliage and plant materials, multitude of hosts could be good or bad for detection; difficult to separate from H. zea (in CA) based on moth genitalia; ongoing genetic studies further muddy this issue.
3
Control
Much research conducted on management; readily develops resistance to pesticides, Bt GMO technology is effective, biological controls helps; pheromones for the adults are known; regardless, still one of the most damaging Lepidoptera pests where it occurs.
