Fig. 8From: Effects of sugarcane aphid herbivory on transcriptional responses of resistant and susceptible sorghumImpact of sorghum genotype and age on average daily change of aphid density. Daily change in aphid density was measured on susceptible and resistant sorghum 2- and 6-wk post emergence. Bars mark means ±1 SEM and means with different letters differed significantly (P ≤ 0.05)Back to article page
