Pecan Twig Girdlers and Pruners: Sanitation Is the Only Control

A 90‑ft pecan suffers from twig girdlers (chew outside‑in) and twig pruners (cut inside‑out). Both are long‑horned beetles. Larvae develop in fallen twigs. Only control: gather and destroy (burn/shred) all fallen twigs in fall/winter. Insecticides impractical. Webworms: spray trunk with Orthene when caterpillars descend to pupate. Damage reduces next year’s nut crop but won’t kill tree.
