Figure 1From: Mutation of a nicotinic acetylcholine receptor β subunit is associated with resistance to neonicotinoid insecticides in the aphid Myzus persicaeInternal concentrations of A) imidacloprid and B) 4/5-hydroxy-imidacloprid from aphids treated with a topical application of imidacloprid. Graphs represent mean recovery of A) imidacloprid (ng mg-1 of aphids) and B) 4/5-hydroxy imidacloprid (relative peak area mg-1 of aphids) ± SE (n = 3 pooled samples of 250 aphids). * Denotes a statistically significant difference between 4106A and FRC clones with p < 0.05 (1-tailed Student's t-test).Back to article page
