1 Estimate based on LS means from analysis of covariance performed in SAS 9.3.
2 Numbers in the same column followed by same letter are not significantly different (P < 0.05) as determined by Dunnett’s method for multiple comparisons to a control.
3 For corn, cotton, and soybean, corn-strain FAW were used in feeding assays.
4 For rice, presumptive rice-strain FAW were used in feeding assays
*indicates P<0.05
**indicates P<0.001.
