Average regression coefficient for the association between <i>Lygus</i> 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<0.1. Number reported is average of the significant regression coefficients in analyses performed at the 12 scales. Parentheses contain standard error followed by number of significant regression coefficients. †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.
