Tolerance of the cry8-like transgenic plants to H. parallela. (a) Representative images of the insect bioassay performed on transgenic soybean plants with H. parallela larvae after 4, 6, and 8 days of feeding. (b) Fresh weight of soybean plants after 8 days of H. parallela larval feeding. The bars represent the means ± standard errors; the mean values followed by the different letters are significantly different (P < 0.05), as determined by Duncan’s multiple-range test. (c) Phenotypes of 25-day-old plants treated with H. parallela for 14 days. Control: Jinong 28; 1–8: Jinong 28-cry-1, Jinong 28-cry-2, Jinong 28-cry-3, Jinong 28-cry-4, Jinong 28-cry-5, Jinong 28-cry-6, Jinong 28-cry-7, and Jinong 28-cry-8; (d) Analysis of the survival rates of seedlings after 14 days of H. parallela feeding. The different uppercase letters indicate significant differences at P < 0.01, as determined by Duncan’s multiple-range test
