Maternal ecdysteroids identified in the vitellogenic oocytes of Schistocerca gregaria included more than 80% polar conjugates, up to 5% free ecdysteroids, and up to 15% non-hydrolyzable polar metabolites. The representations of ecdysone (E), 20hydroxyecdysone (20E), and 2-deoxyecdysone (2dE) in the
I n the penultimate and last instar larvae of Schistocerca gregaria, 20hydroxyecdysone (20E) makes up 7484% of detected ecdysteroids i n the females, and 63-74% i n the males. Remaining ecdysteroids include ecdysone, a compound with HPLC and TLC retention times of makisterone A, and highly polar met
