ABSTRACT
This paper reveiws the history of the pink bollworm pest management project in California with emphasis on the last 4 years in the Imperial Valley. This project uses release of sterile insects, cultural controls, intensive monitoring with pheromone baited traps for adult males and boll sampling, pheromone applications for mating disruption, very limited use of pesticides and, recently, widespread use of genetically engineered cotton. Results indicate good control of local pest populations. A major concern is migration from nearby, heavily infested fields, over which we have no control. Recommendations for future projects are discussed.
