Larvae of Culex tarsalis, a mosquito, are capable of surviving and developing in dilutions of sea water ranging from 0 mosmol l-1 to 700 mosmol l-1. In waters more dilute than 400 mosmol l-1, the larvae osmoregulate, whereas in those more concentrated than 400 mosmol l-1, the osmotic strength of the haemolymph parallels that of the medium, i.e. the larvae osmoconform. Over the full range of external concentrations tested, the larvae regulate the levels of Na+, K+, Mg2+, Ca2+ and Cl- in the haemolymph. Analyses of haemolymph samples from larvae adapted to media of 50 mosmol l-1 or 600 mosmol l-1 indicate that the increase in haemolymph osmotic concentration observed in media above 400 mosmol l-1 is due to the accumulation of organic compounds, particularly proline, serine and trehalose.
致倦库蚊幼虫能够在稀释度从0毫渗透压摩尔每升至700毫渗透压摩尔每升的海水中存活并发育。在稀释度高于400毫渗透压摩尔每升的水中，幼虫进行渗透调节；而在浓度高于400毫渗透压摩尔每升的水中，血淋巴的渗透强度与介质的渗透强度相当，即幼虫进行渗透顺应。在测试的整个外部浓度范围内，幼虫调节血淋巴中Na⁺、K⁺、Mg²⁺、Ca²⁺和Cl⁻的水平。对适应于50毫渗透压摩尔每升或600毫渗透压摩尔每升介质的幼虫血淋巴样本的分析表明，在高于400毫渗透压摩尔每升的介质中观察到的血淋巴渗透浓度增加是由于有机化合物的积累，特别是脯氨酸、丝氨酸和海藻糖。
