Table 2. Effects of the injection of SeTre-1 or SeTre-2 dsRNA on the chitin content in epidermis (Ep) and midgut (Mg) of S. exigua larvae.

	Group	Content (ug chitin/S. exigua)
Ep	dsGFP	65.15±0.50 a
	dsSeTre-1	44.56±1.90 b
	dsSeTre-2	57.12±1.04 c
Mg	dsGFP	2.04±0.90 a
	dsSeTre-1	1.99±0.10 a
	dsSeTre-2	1.42±0.07 b

Each data point is the mean ± SEM of three independent experiments with ten abnormal individuals each (n = 30). Different letters indicate significant differences of the chitin content (p<0.05, LSR, SPSS).
