Damage caused by pecan nut casebearer

Pecan Nut CasebearerThe pecan nut casebearer is present in all pecan-growing areas of Texas and can cause serious crop loss almost every year if left uncontrolled. Casebearer larvae or caterpillars feed inside pecan nuts. First-generation larvae feed inside small nutlets from April to June. This generation is most damaging, as a single larva often destroys all the nutlets in a cluster.

Second generation Damage

Larvae of later generations require just one or two nuts to complete their feeding, as pecans are larger at that time.
