Interpretive Summary: .

Technical Abstract: The pecan bud moth, Gretchena bolliana (Slingerland) (Lepidoptera: Tortricidae), is an invasive pest in Arizona and has likely gained a foothold relatively free from the limiting effects of natural enemies that have not caught up with its westward movement, i.e., the enemies release hypothesis. This situation could allow G. bolliana populations to increase faster and higher in a short time. At least some natural enemies of G. bolliana will eventually follow it into this desert environment and provide a level of control. At present, but also likely for some time to come, management will be through insecticides specifically targeting G. bolliana larvae. Fortunately, the products available for management of the pecan nut casebearer, Acrobasis nuxvorella Neunzig (Lepidoptera: Pyralidae), and hickory shuckworm, Cydia caryana Fitch (Lepidoptera: Tortricidae), can provide effective management of pecan bud moth. A management program is being developed.
