Virgin female traps aid control survey for omnivorous leaf roller in San Joaquin Valley vineyards
Abstract Not Available – First paragraph follows: Early identification of pest species is essential to the successful planning and operation of integrated control and pest management programs. Growers can then minimize the damages caused by insects though timely manipulation of various control measures, including chemical treatments, cultural practices, and harvest schedules. Detection and survey methods used include the hand search for both mature and immature stages, direct collection by D-Vac (a suction insect collecting device), sweep nets, a study of the damage index, and use of various types of traps. Black light traps have usually been used for surveys; however in recent years, the pheromone trap has become more common.
