Abstract Measuring the linear characteristics of chironomid larvae is easier and faster than measuring their mass. The relationships between them are approximated by parabolic equations. Generalized equations are provided for all chironomid larvae. However, these relations vary in different water bodies. Measurements of 1424 chironomid larvae representing several species were taken in Crimean waters with salinity ranging from 0 to 280 PSU. There was a high correlation between three traits. In the case of Baeotendipes noctivagus and Cricotopus gr. sylvestris, dimorphism was found in the “head capsule length– width” relationship. Salinity affects the head capsule. The exponent “b” varied from 1.43 to 3.06 in the “body length-mass” equation for B. noctivagus, and from 1.943 to 2.592 for C. gr. sylvestris. It is inappropriate to use only one coefficient “b” for all chironomid larvae. In B. noctivagus and Paratanytarsus confuses, the mass of one-size larvae decreased with increasing salinity. Salinity is not the only factor affecting the size and mass of chironomid larvae.

盐度是否会影响高度耐盐的 Baeotendipes noctivagus 幼虫（双翅目、摇蚊科）的身体比例和“大小/质量”比率？

摘要 测量摇蚊幼虫的线性特征比测量它们的质量更容易、更快捷。它们之间的关系由抛物线方程近似。为所有摇蚊幼虫提供了广义方程。然而，这些关系在不同的水体中有所不同。在克里米亚水域对 1424 只摇蚊幼虫进行了测量，该水域的盐度为 0 到 280 PSU。三个特征之间存在高度相关性。在 Baeotendipes noctivagus 和 Cricotopus gr 的情况下。sylvestris，在“头囊长-宽”关系中发现了二态性。盐度影响头部胶囊。在 B. noctivagus 的“体长-质量”方程中，指数“b”从 1.43 到 3.06 变化，对于 C. gr. 从 1.943 到 2.592。樟子松。对所有摇蚊幼虫只使用一个系数“b”是不合适的。在 B. noctivagus 和 Paratanytarsus 混淆中，一尺寸幼虫的质量随着盐度的增加而减少。盐度不是影响摇蚊幼虫大小和质量的唯一因素。
