Dynamics of P. japonica adults on maize patches of four area proportions.

Densities of P. japonica adults in maize patches of four area proportions: 25%, 50%, 75% and 100% of maize in field landscape plots in 2008 (A), 2009 (B), and 2010 (C). *Significant differences between densities of P. japonica adults in maize patches of four area proportions at p<0.05. **Significant differences between densities of P. japonica adults in maize patches of four area proportions at p<0.01. Densities of accumulative P. japonica adults in maize patches of four area proportions at all sample dates of field landscape plots in 2008 (D), 2009 (E) or 2010 (F). Different lowercases above the bars indicate significant differences in densities of accumulative P. japonica adults in maize patches of four area proportions at p<0.05. Data are presented as adults per square meter of crop plants (mean±SE) with separate field landscape plots used as replicates. Sample size of cotton patch and maize patch are both 5. N indicates the size of samples tested.
