Impact of high PPC on the ovarian development

(A) Adult ovary. M0, newly molted adult stage. G, germarium. OO, oviporous orifice. O, oviductus. OT, ovarian tube.

(B) Weight and length of ovaries in M0.

(C) Ovaries with similar morphology in W. OM, ovarian outer membrane.

(D) Ovaries with different morphology in PP. Ruptured OM indicates faster ovarian development.

(E) Developmental morphology of ovaries in P2-P6.

(F) Development status of eggs in P6. Enlarged view of the ovarian tube with the red box in (E). Mature eggs appear white.

(G–I) Number of mature eggs in P6. Ovarian weight (H) and Gonadosomatic index (I) from W to P8 stages (n = 3).

Data in (B, G, H, and I) were the mean ± SD, and the significance of the difference in the Student’s t test was ns, p > 0.05; ∗, p < 0.05; ∗∗, p < 0.01; ∗∗∗, p < 0.001.
