Role of neuro endocrine system on the function of male accessory reproductive glands (MARG) in a
cotton bug

T
he neuroendocrine complex of adult insects consists of neurosecretory cells (NSC) of the brain, corpora cardiaca (CC),
and corpora allata (CA). Following the pioneering work of Weyer (1935) in honeybees, several investigators have been
explored on the histomorphology of NSC, CC and CA in many orders of insects including in hemipteran insects. The present
study is dealt the regulatory mechanism of the male accessory reproductive glands (MARG) of a hemipteran cotton pest
Serinetha augur
. Histological and electrophoretic studies were made to understand the interrelationship of the neuroendocrine
complex (NEC) and the MARG of the insect. The brain of
Serinetha augur
is divisible into three regions, namely proto-deuto
and tritocerebrum. Protocerebrum lies at the anterior region, deutocerebrum is in the latero mid region and tritocerebrum is
in the latero posterior region of the brain. The neurosecretory cells (NSC) in the brain complex have been arbitrarily classified
into four types (A, B, C and D) and are connected by pars intercerebralis. NSC in this region is distinguished as median
neuro secretory cells (MNC). Among NSC identified in three regions of the brain of
Serinetha augur
A is found larger (13-
18 microns) which is located in tritocerebrum with weak reaction of chrom alum haematoxylin and phloxin (CAHP) due to
lower concentration of neurosecretory materials. The type B are 10-12 microns situated in protocerebral region with higher
concentration of neurosecretory materials. C and D are moderate and weak reaction respectively with aldehyde fuchsin (AF)
and CAHP indicate lesser amounts of neurosecretion. On the regulation of the MARG, it was understood that CA took part
directly for its maturation and function. It was proved by the experiments of gonadectomy and extirpation of the MARG.
Besides, electropherogram of brain complex in pre and post mating insects showed the quantitative changes of protein. This
observation further supports the view that NSC in brain complex has a regulatory role in the MARG which has varieties of vital
functions in sperm transfer activities.
Biography
Parasuraman Basker had been awarded Doctoral degree in zoology fromAnnamalai University, Tamil Nadu, India. Following it he was Research Associate in ICAR
and UGC research projects on the fauna of Carabids (Coleopteran Insect) in South India and mosquito cytogenetics in the University of Agricultural Sciences,
Bangalore and Bangalore University respectively. Subsequently, he was posted as Senior Entomologist in 1995 in the Department of public Health and Preventive
Medicine through Tamil Nadu Public Service Commission (TNPSC). In his credit 33 Research Abstracts presented in 8 International and 25 National Conferences
since 1983. 21 research papers have been published in reputed national and international journals. He visited Canada, Malaysia, Morocco, Singapore and Spain
as presenters with the Government of India Travel Grants (CSIR, INSA, ICMR and NRHM).
