Juvenile hormone (JH) biosynthesis by corpora allata (CAI from embryos of the cockroach Diploptera punctata was measured at four stages during the latter half of embryogenesis. Individual glands from 32-day-old embryos that had completed 49% of embryonic development synthesized 0.3 pmol JH Ill h-'.
In the cockroach Diploptera punctata, sequencing of the cDNA for the insect myoinhibitory neuropeptide, leucomyosuppressin (LMS), has demonstrated that LMS is the only Phe-Met-Arg-Phe-amide (NH 2 ) (FMRFamide)-related peptide to be encoded by this gene (Donly et al. [1996] Insect Biochem. Mol. Biol.
A mitotic wave before an increase in juvenile hormone (JH) synthesis was observed in the corpora allata during each ovarian cycle in the cockroach Diploptera punctata and was shown subsequently to be inhibited by the brain until adult females mated. Each corpus allatum (CA) was innervated by groups
Unlike in Blettelta gcrmanica and Supella longipalpa, the corpora allata (CAI of Diploptera punctafa exhibited cyclic changes in cell number during the reproductive cycle. In mated females, a wave of DNA synthesis followed by mitosis resulted in a significant increase in CA cell number from about 9,
