Abstract:
The BWDISP (Boll Weevil DISPersal) model is a stochastic simulation model
that predicts the spread of boll weevil populations on cotton, given certain
weather conditions (McKibben et al., 1991).
The model requires weather data (daily maximum and minimum temperature),
wind speed and cotton field size as input data. Output of the model
includes a probability distribution for the boll weevil population dispersal.

VI. Additional remarks
Global change implications:The boll weevil is one of the mostcrop-damaging insects that models have been developed to study. Because the development and dispersal of this insect is sensitiveto temperature, it will be important to understand how thisinsect will potentially respond to climate change. In addition,without proper management of this pest, other secondary pests(primarily bollworms) may attack the crop.
