Figure 4. Increase in basal oocyte length (A) and juvenile hormone (JH) synthesis (B) following implantation of a previtellogenic ovary or 2 ovarioles from a vitellogenic or late vitellogenic ovary (basal oocytes 0.70, 1.00, 1.50 mm in length respectively) into 4 day adult males with corpora allata denervated on day 1. Controls received saline. Each column shows the mean ± SEM of the number of individual measurements above the column. The data for 1.00 mm basal oocytes and corresponding saline controls is from Figure 2 males with denervated corpora allata.
