A progress report… bilogical control of pink bollworm in cotton
1970
B Bartlett | D Gonzalez
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.
