Haemolymph modifications during starvation in Philosamia cynthia walkeri (ferber)—I. Volume, osmotic pressure, pH; relation to intracellular water content

Osmotic regulation in adultDrosophila melanogasterduring dehydration and rehydration

“…Insects exhibit a much larger variation in the concentration of the extracellular fluid, both individually and in response to environmental variation, than do vertebrates (Buck, 1953;Jeuniaux, 1971;Bosquet, 1977). It has been argued that the selectively permeable sheath that protects the insect central nervous system permits a greater tolerance of both osmotic and ionic variability in the hemolymph (Treherne and Pichon, 1973;Jones, 1977;Ashhurst, 1985).…”
