Acid-Base Balance and Nitrogen Excretion in Invertebrates ISBN: 9783319396156
This chapter reviews the current knowledge about acid–base loops in larval insects, focusing on two species that have become model organisms for this physiological process: tobacco hornworms (Manduca sexta) and larval yellow-fever mosquitoes (Aedes

The gut contents of larval mosquitoes are alkalinized by the anterior midgut and reacidified by the posterior midgut. In the present study the cellular mechanisms of reacidification were studied in isolated, perfused posterior midgut by measuring the

Isolated anterior midguts of larval Aedes aegypti were bathed in aerated mosquito saline containing serotonin (0.2 µmol L−1) and perfused with NaCl (100 mmol L−1). The lumen negative transepithelial voltage (Vte) was measured and luminal alkalin

Recently, Na + /K + -ATPase has been detected in the luminal membrane of the anterior midgut of larval yellow fever mosquitoes (Aedes aegypti) with immunohistochemical techniques. In this study, the possible involvement of this ATPase in strong alkal

In the present study, isolated midguts of larval Aedes aegypti L. (Diptera: Culicidae) were mounted on perfusion pipettes and bathed in high buffer mosquito saline. With low buffer perfusion saline, containing m-cresol purple, transepithelial voltage

These studies focus on the pupal Aedes aegypti midgut muscularis for the first 26 h following larval-pupal transition. The midgut muscularis of Ae. aegypti pupae during this first half of the pupal stadium is a grid of both circularly and longitudina

Serotonin regulates key processes including digestion and homeostasis in insects. Serotonin effects are mediated by serotonin receptors that transduce information through initiation of second messenger signaling pathways. Lack of information on serot

The transepithelial voltage ( V te ) and the volume of isolated posterior midguts of adult female yellow fever mosquitoes ( Aedes aegypti ) were monitored. In all experiments, the initial V te after filling the midgut was lumen negative, but subseque

In all life stages, the gut of the mosquito is innervated by a small number (typically 4) of central neurons immunoreactive to serotonin (SI). The serotonergic system appears to pass through metamorphosis largely intact, despite extensive remodeling

SUMMARY The present investigation studied the influence of a number of neuropeptides on semi-open preparations of the isolated and perfused anterior stomach of larval Aedes aegypti . Effects of peptides were observed on the lumen negative transepithe
