In southern North Carolina, we should reach peak migration of adult kudzu bugs into soybeans this week.
Some fields have already reached one nymph per sweep, with population densities so large they will require a re-spray.
One variety in a graduate student experiment in Montgomery County is averaging around 50 kudzu bugs per sweep- 50 times the threshold. Most varieties are around 3 bugs per sweep. Expect the migration to peak a bit later in areas farther north.
