Webrelease of the ovarian ecdysteroidogenic hormone from the medial neurosecretory cells of the brain for up to 12 h after feeding (5, 6). In response to ovarian ecdysteroidogenic hormone, the ovary produces ecdysone, which is converted into an active form of the hormone 20E (7). 20E titers are only slightly elevated at 4 h WebJan 1, 2016 · Neuroparsins (NPs)/ovary ecdysteroidogenic hormone (OEH) are large peptides that belong to the most cysteine-rich family of neurohormones. NPs inhibit vitellogenesis in locusts, whereas OEH stimulates vitellogenesis by virtue of its stimulation of ecdysone synthesis by the ovary in the female mosquito.
