title: Oogenesis in Mylabris pustulata (Coleoptera): origin and composition of compound yolk.
abstract: Three categories of compound yolks are synthesized during vitellogenesis of Mylabris pustulata. CY1 bodies originate de novo and are composed of protein-carbohydrate (glycogen)-RNA complex. CY2 bodies originate from precursors in follicular epithelium and are composed of protein-carbohydrate (glycogen) complex. CY3 bodies originate from extraovarian precursors and are composed of protein-acid mucopolysaccharide-glycogen-phospholipid complex.
