The Orgyia DH was injected into LD-pupae at various doses, and analyzed for diapause egg inducing activity (A), glycogen content (B), maximum diameter of follicles (C), eggshell thickness (D), ovary weight (E), number of follicles (F), body weight (G), and rate of ovarian weight (H). Furthermore, anti-FXPRLa serum (+) and pre-immuno serum (−) were injected into SD-pupae to examine the DH functions as described in the text. Each bar represents the mean value of 10 samples ± SD. Lower-case letters indicate statistically significant differences at the 5% level in DH-injected animals at 0 pmol in LD vs. pre-immuno serum-injected animals in SD (a), DH-injected animals at 0 pmol in LD vs. DH-injected animals at various doses (b), and pre-immuno serum-injected animals in SD vs. anti-FXPRLa-injected animals (c).
