abstract

Long-range studies on cotton bollworm were initiated to develop control recommendations relating damage potential to pest population density, environmental conditions, and the general economics of cotton production. Data from these preliminary studies indicate that the present criteria used in determining the economic threshold for cotton bollworm need to be re-evaluated. The data suggest that higher infestations of cotton bollworm may be tolerated than previously believed.
