The general morphology of the complex of endocrine glands in Chironomus thummi is described (corpora allata, peritracheal glands, cardial bodies). Each of these glands is characterized during the 3rd, 4th larval instars and metamorphosis by specific developmental features. Enlargement of corpora allata is due, mainly, to more than 10-fold increase in cell number. The process of growth in the peritracheal gland is realized mainly at the expense of increase in cell size and formation of polytene nuclei; the latter is witnessed both by nuclear morphology and increase of DNA content per nucleus. It was shown by cytophotometric measurements that DNA content per nucleus in the peritracheal gland of a just moulted larva of the 4th instar amounts to 0.202 +/- 0.02 relative units, in prepupa to 2.98+/-0.01, whereas the corresponding values for nuclei of corpora allata equal 0.107+/-0.01 and 0.212+/-0.1. The number of cells and the morphology of nuclei suffer no significant changes in cardial bodies but 2 giant cells intimately connected with cardial bodies increase in volume from 18 to 200,000 mu3 and typical polytene chromosomes form in them.
描述了摇蚊（Chironomus thummi）内分泌腺复合体的一般形态（咽侧体、围气管腺、心体）。在幼虫的第3、4龄期以及变态过程中，这些腺体各自具有特定的发育特征。咽侧体的增大主要是由于细胞数量增加了10倍以上。围气管腺的生长过程主要通过细胞大小的增加和多线核的形成来实现；这一点从核形态以及每个细胞核DNA含量的增加都可以得到证明。细胞光度测量表明，刚蜕皮的4龄幼虫围气管腺细胞核的DNA含量为0.202±0.02相对单位，预蛹期为2.98±0.01，而咽侧体细胞核的相应值分别为0.107±0.01和0.212±0.1。心体中的细胞数量和核形态没有明显变化，但与心体紧密相连的2个巨型细胞体积从18立方微米增加到200,000立方微米，并在其中形成典型的多线染色体。
