“…Despite morphological alterations of the corpus allatum due to ageing (Awasthi 1972) compact and homogeneous nature and posses sion of dimorphic nuclei indicate its synthetic role (Lea and Thomsen 1962). Occurrence of interdigital processes in some inactive glands has a definite physi ological significance and could be recognised as a marker of synthetic activity as envisaged by B.…”

“…The first type are called "A cells," while the second type are called "B cells" (Dai et al, 1987). Classification of MNCs into A and B cells using histochemical staining affinities and cytomorphology has also been made in another article by Hsiao and Fraenkel (1966) in Phormia regina, and in other species of Musca nebulo Bhaskaran, 1966 -1967b), Musca domestica (Ramade, 1969), Sarcophaga ruficornis (Awasthi, 1972), Calliphora vicina, Lucilia caesar (Panov, 1976), and Lyperosia exigua (Khurad and Thakare, 1980). These differences in histochemical properties and cytomorphology may suggest different physiological properties of these neurons.…”

“…Figure 5 shows neurons stained through the CRN after the right NCC had been Awasthi (1972) severed in Protophormia terraenovae to stain neurons extending to the left NCC . A large cluster of cell bodies is located in the contralateral (right) PI.…”

“…Histochemical staining with PAF or CH revealed relatively few cells in the PL. In Drosophila funebris, Calliphora vicina, Phormia regina, Musca nebulo, and Sarcophaga ruficornis, 2-4 pairs of LNCs were stained in the PL (Awasthi, 1972;Bhaskaran, 1966 -1967b;Hsiao and Fraenkel, 1966;Köpf, 1957;Thomsen, 1965). In most cases, these cells are situated superficially below the layer of perineural cells.…”

In the larval brain of dipteran insects, there are two medial and three lateral groups of neurons innervating the ring gland. One lateral group extends fibers to the corpus allatum. After metamorphosis, a large cluster of the medial group in the pars intercerebralis and two lateral groups in the pars lateralis innervate the retrocerebral complex and some neurons from the lateral group and a few from the medial group extend fibers to the corpus allatum in the adults. Neuropeptides such as insulin-like peptides, FMRFamide related peptides, Locusta-diuretic hormone, beta-pigment dispersing hormone, Manduca sexta-allatostatin, ovary ecdysteroidogenic hormone, and proctolin have been immunocytochemically revealed in medial groups in the pars intercerebralis, and FMRFamide related peptides, beta-pigment dispersing hormone, corazonin, and M. sexta-allatostatin in lateral groups in the pars lateralis of dipteran brains. In mosquitoes after the blood meal, ovary ecdysteroidogenic hormone from 2-3 pairs of medial neurosecretory cells is released at the corpus cardiacum to stimulate the ovaries to secrete ecdysteroid to cause ovarian development. In addition to ovarian development, removal and implantation experiments have shown that neurosecretory cells in the pars intercerebralis and pars lateralis are involved in control of reproductive diapause, cuticular tanning, sugar metabolism, and diures.

The axonal connections of the corpus allatum of Dysdercus similis have been investigated in detail. Apart from the two already known nervi corpori cardiaci (NCC I & NCC II) of each side, additional axonal connections between the Corpora Cardiaca (CC) and the aortal wall, between the corpus allatum and the aortal wall and between the corpus allatum and the oesophagus have been noted for the first time. The importance of the corpus cardiacum as the main neurohaemal organ vis‐a‐vis the terminal axons of nervi allati aorti (NAA) and/or the aortal wall, has been discussed.
