Maternal frass is necessary for embryonic development in Weiseana barkeri Jacoby (Coleoptera: Chrysomelidae)
Australian Journal of Entomology 36 (1), 95-96
Abstract: Eggs of Weiseana barkeri, a potential biological control agent for Acacia nilotica, are laid in batches covered in frass. An experiment measuring embryonic development in eggs with and without a frass covering indicated the presence of frass is necessary for the termination of diapause and the initiation of development in egg batches.
