- Diploptera punctata is a tropical omnivorous cockroach found in ground litter or burrowing under rocks and logs, is currently known to be truly viviparous. D. punctata embryos develop within the body cavity of females in the brood sac, an invagination of the ventral intersegmental membrane which provides nutritive secretions (milk) to the developing embryos. The main components of this milk are hydrosoluble proteins, rich in many essential amino acids, particularly leucine, valine, and lysine, but deficient in methionine and tryptophan. Methionine and tryptophan are presumably acquired from the vertically transmitted Blattabacterium present in the fat body of developing embryos, or possibly from gut microbiota. The cockroach Diploptera punctata has proven to be an ideal model organism in the study of juvenile hormone (JH). D. punctata is the only known truly viviparous cockroach. Because of this remarkable feature, the rate of JH production is tightly controlled during the animal’s reproductive cycle. High rates of JH biosynthesis in their CA are coordinated with a very precise and predictable order of reproductive events, making this cockroach an ideal model for studying the regulation of JH production .
