Japanese and Oriental Beetles
Beetles move into basil after emerging from soil in turf, pastures, or fallow areas, starting in late June and peaking in July. Adult beetles skeletonize leaves as they feed. Row covers can prevent feeding, but watch for build-up of aphids due to exclusion of natural enemies. The basil variety Nufar is very attractive to Japanese beetles and can be used for a trap crop.
