ADULT EMERGENCE PATTERNS, POPULATION TRENDS AND ACTIVITY PATTERNS OF THE HICKORY SHUCKWORM, CYDIA-CARYANA (LEPIDOPTERA, TORTRICIDAE, OLETHREUTINAE) IN PECAN ORCHARDS

Emergence of hickory shuckworm, Cydia, caryana (Pitch), adults from la rval overwintering sites was bimodal. The major emergence peak occurre d during the period of mid-March to mid-May and the smaller activity p eriod during July and August. Pheromone trapping was effective for mon itoring population trends during generations 1 and 5 of C. caryana but less so during generations 2, 3, and 4. Activity patterns suggest the species is crepuscular rather than truly nocturnal.
