They use the same, but larger, setup on big farming operations to know when to spray for the buggers, otherwise they're just wasting spray. I will do the same, but won't spray until I see corn earworms show up. Every moth I've caught so far, I think, has been the Southwest corn borer. And with just 3-4 weeks till the plants will be finished, I don't see the SCB's causing too much trouble this go round.Interesting. I'll be following this to see how your corn comes out.
