TI - A progress report… bilogical control of pink bollworm in cotton JF - California Agriculture JO - Calif Agr Y1 - 1970/01/01 VL - 24 IS - 1 SP - 12 EP - 14 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v024n01p12 AB - Since the invasion of Southern California desert cotton-growing areas by the pink bollworm in 1965, attempts at its eradication have been unsuccessful. In Arizona (with a longer history of permanently established infestations of this pest) its severity under similar desert growing conditions has resulted in losses estimated at from $50-$75 per acre. In both states, available chemical materials have proven very costly and less effective than hoped for and they have prompted outbreaks of several secondary pests.
