Fig. 6.

Relative expression levels of Aohsp70 (A) and Aohsp90 (B) at different developmental stages between macropters and brachypters. The different letters on the error bars indicated a significant difference at the 0.05 level (Tukey’s test). The capital letters represented macropters and the lower-case letters represented brachypters. The asterisks above the bars indicated a significant difference between the two morphs (t-test, *0.001 < P < 0.01 and **P < 0.001). Data are presented as mean ± SE.
