Weather Factors Affecting Long-Range Dispersal of the Boll Weevil

Gerald H. McKibben and James W. Smith


 
ABSTRACT

Various weather factors are discussed as they relate to long range transport of the Boll Weevil, Anthonomus grandis Boheman. A simulation model for studying boll weevil dispersion is discussed. The model uses boll weevil flight speed and duration coupled with wind data to simulate distance traveled. The population of weevils is produced by a population dynamics model which produces a simulated population realistically distributed over the growing season. The dispersal module then produces a distance distribution of the weevils leaving the field each day.
