Each cotton plant growing in the plot was examined visually for a short period of time to ascertain the presence or absence of A. gossypii and to construct weekly infestation maps. Tests of autocorrelation and dispersion were carried out at different spatial scales by means of Monte Carlo procedures on embedded counting grids. Edge effect tests were also carried out. The statistical analyses show significant overdispersion of the infested plants and positive spatial autocorrelation. Positive temporal autocorrelation and significant edge effect are detected intermittently throughout the season.
