Abstract
The changes of concentrations of Na and Cl in the haemolymph of fourth instar larvae of Culex pipiens pallens Coquillet, Culex pipiens molestus Forskal, Aedes albopictus Skuse and Aedes togoi Theobald, which were caused by treatment with artificial sea waters of various concentrations, were measured by radioactivation analysis. C. p. pallens showed no salt regulation (Fig. 1), but those reared in 20% sea water from first to fourth instar acquired a little ability of the salt regulation (Fig. 6). C. p. molestus was superior a little to C. p. pallens in salt regulation (Fig. 2), and A. albopictus was much more superior than the formers (Fig. 3). A. togoi reared in fresh water has an excellent ability of salt regulation (Fig. 4). In the highly concentrated 140% sea water, Na and Cl increased to the maximum values in about 10 hours. After 22 hours they decreased to ordinary concentrations (Fig. 5). This phenomenon shows that the additional strong function of salt regulation is prepared in 10 hours by their acclimation to the highly concentrated sea water. Water temperature renders much influence for the larvae to aquire this function. The concentrations of Na and Cl changed at different rates, and Cl always changed faster than Na.
