Abstract
Embryogenesis of a polyembryonic wasp, Litomastix maculata, was studied in vivo and in vitro. In vivo, eggs cleaved holoblastically and then developed into morulae within the first 24 hr. Subsequently, the morula produced polygerms. A similar process was also induced in a modified MGM 450 medium. Bovine plasma albumin was required as a component of the medium for the embryos to develop up to the complete morula. Ovalbumin and conalbumin also supported the development of the embryos, whereas lactalbumin was rather detrimental.
