Changes in the neuroendocrine system during post-embryonic development in the buffalo-fly, Lyperosia exigua (De Meijere) (Diptera: Muscidae).
The neurosecretory cells of the pars intercerebralis and ring gland are examined in histological sections of larva, pupa and adult of buffalo-fly, Lyperosia exigua fixed at various intervals during the rpost-embryonic development. Three paired medial groups of the neurosecretory cells are observed in the larval brain. These groups show their displacement during the larval-pupal-adult moult. The medial neurosecretory A cells exhibit secretory activity by undergoing cyclic changes of synthesis and release during post-embryonic development. The ecdysial glands and a single corpus allatum also undergo cyclical changes in volume and histological appearance in accordance with the larval-pupal-adult moult.
