Sorghum stalk pith effects on H. zea and S. frugiperda larvae

	H. zea, % mortality	S. frugiperda, % mortality
Experiment 1
Wild-type	1.7a	10.4a
bmr6	36.4b*	27.7b
bmr12	29.9b*	25.5b
Experiment 2
Wild-type	6.4a	2.7a
bmr6	47.3b*	21.2b*
bmr12	37.3b *	34.0b*

Pith from at least eight plants of each line was used. Values followed by different letters for the same experiment are significantly different at P < 0.05 by Chi square analysis. Values of bmr (low lignin) lines in columns for the same experiment followed by a “*” are significantly different from wild-type (normal lignin) values at P < 0.01.
