The Effect of Short-Season Cotton Systems on Pest Insect Populations

T.J. Henneberry


The pink bollworm, Pectinophora gossypiella (Saunders), boll weevil, Anthonomous grandis Boheman and Heliothis spp are pests of major concern in southwestern desert cotton-growing areas of the United States. Mild spring and fall temperatures have encouraged full-season production systems where cotton often remains in the field 10 to 12 months (Willet et al., 1973). Insecticides are generally applied from early July to late September, but late-season bolls remain unprotected since they seldom mature and produce lint. They do, however, serve as a source of host material that produces high overwintering insect populations.
