Abstract:Carryover of pink bollworms(Pectinophora gossypiella(Saunders)) from one cotton crop to the next under five cultural practices commonly used in central Texas was studied over a 3-year period. Date and depth of burial of the cotton-crop residue were important factors influencing mortality. Flat-breaking the land with a moldboard plow to a maximum 6-inch depth in November, followed by listing in February, gave significantly greater control than the other treatments tested. Winter survival was lower and suicidal moth emergence higher in the plowed plots. Moldboard plows gave greater control than Intertype plows. The winter cover crop of oats greatly delayed spring and summer emergence of the insect, thus greatly increasing the number of moths that emerged to infest cotton. A winter cover or forage crop of oats or similar crops to be left for harvest should not follow cotton in the rotation program unless the land is plowed prior to such plantings.
