Average regression coefficient for the association between Lygus density in sampled cotton fields and abundance of crops and uncultivated habitats, estimated for two sampling periods in three years.

Effects of flowering date and insecticide sprays are also shown.*After correcting for spatial autocorrelation, criterion for assessing significance of regression coefficients was P†NA: Standard error was not calculated because a single coefficient was significant, or a crop was not included in analyses because it was rare in rings.
