How has the ability to scout for Japanese beetles provided benefit to your farm?
Japanese beetles have been very prevalent in our area in the last two to three years I'd say. We started noticing them when they would be flying around and everybody was asking, "What in the world is this bug that we keep seeing?" So, we started doing some research and figuring out what they were and then trying to figure out how to scout them. We noticed, we went around the edge of the field and they were more prevalent in the edge of the field rather than out in the middle. When you're scouting for Japanese beetles in corn, what you're looking for is if they're clipping the silks on the ears or a part of the tassel that would be bad too. And then also in beans, you're looking for a defoliation on how many percentages of the leaf is gone. And until you treat it, it's 50%, which is a lot on a bean leaf.
