Boll weevil overwinter survival and spring emergence predictions are pivotal to the development of an IPM program in which the boll weevil is the key pest. Traditional predictions were based on the previous year's boll weevil population levels, fall crop maturity, weather conditions and experience. Computerized predictions based on continually updated climatic conditions, an index of boll weevil density and years of research data should increase the accuracy of predictions. IPM programs in which management of other pests is designed around boll weevil management can use these predictions to develop more effective programs.
