Ovarioles as a Meristic Character in Coleoptera

Article metrics

Abstract

INSECT ovaries are bilateral structures (except in certain aphids) which contain 1–3,000 egg tubes or ovarioles. In Coleoptera, the ovarioles are polytrophic and acrotrophic in the sub-orders Adephaga and Polyphaga, respectively (see, however, Bonhag1). As the meristic nature of the beetle ovary has not been particularly studied, and because of the possible importance of the ovariole number as an aid to systematics, a study was undertaken.
