Neuroendocrine Systems

The anatomical relations of the neuroendocrine systems of simuliid larvae Prosimulium mixtum/fuscum and Simulium venustum were examined histologically. The neuroendocrine system in the brain showed morphological similarities to culicids (viz., three pairs of cerebral neurosecretory cell clusters, one pair of nervi corporis cardiaci entering the corpus cardiacum glandular system). The retrocerebral glandular portion of the neuroendocrine system was comprised of a corpus allatum, corpora cardiaca, and surrounding peritracheal gland. The morphology of the blackfly neuroendocrine system is discussed in relation to those of other families of Nematocera and higher Diptera.

The diuresis which follows the pupal-adult ecdysis of Pieris brassicae is hormonally controlled. Use of the isolated Malpighian tubules as a bioassay shows the presence of substantial diuretic activity in homogenates of the brain and corpus cardiacum-corpus allatum complex. The hormone is probably produced in the brain and released from a storage site in the corpora cardiaca. The tubules of the butterfly are maximally responsive to the diuretic hormone at the time of eclosion.

Stimulation Of

1. The electrical resistance across the tips of the maxillary palps is not affected by stimulation of the palps, but increases to the normal level found after feeding as a result of distension of the foregut with agar or injection of corpus cardiacum homogenates into the haemolymph. 2. No increase in resistance occurs if the posterior pharyngeal nerves or the frontal connectives are cut. 3. It is inferred that distension of the foregut stimulates stretch receptors which, acting via the posterior pharyngeal nerves, the frontal connectives and the brain, cause the release of hormone from the storage lobes of the corpora cardiaca. This hormone acts on the terminal sensilla of the palps, causing them to close and so increasing the resistance across the palps. 4. Release of the diuretic hormone is controlled via the same pathway.
