The entire nut cluster can be destroyed by a single casebearer larvae
We scouted our "no-spray" native pecan grove today and found 3.3% of the nut clusters infested by pecan nut casebearer larvae. The warm, dry weather we are currently experiencing has caused insect development to move quickly. All northern pecan producers should be carefully scouting their orchards at this time. The window for effective economic control of this pest is rapidly drawing to a close.
