(A) Diagram of the experimental design to analyze the role of BgSvp-B in the second gonadotrophic cycle of adult B. germanica. (B) Basal oocyte length of 5-day-old Control and BgSvp-1i adult females. Results are expressed as the mean S.E. (n = 15–20). (C–E) Transcript levels of BgVg in the fat body (C), BgHMG-S1 and BgHMG-R in the CA (D), and BgHMG-S1 and BgHMG-R in the fat body (E) of second gonadotrophic cycle 5-day-old Control and BgSvp-Bi adults, measured by qRT-PCR. Transcript abundance values are normalized against the BgActin5C transcript. Error bars indicate the SEM (n = 5–10). Asterisks indicate differences statistically significant (*p ≤ 0.05; ***p ≤ 0.0005, Student’s t-test).
