Description
Українська: Гідростатичній апарат личинки комара коретра. На фото показані великі трахейні бульбашки. Ці бульбашки є гідростатичним апаратом. Вони тримають личинку в воді в горизонтальному положенні і допомагають регулювати глибину занурення. Бульбашки покриті клітинами з темним пігментом, які можуть змінювати розмір. Якщо клітини розширені то через поглинання ними світла трахейні бульбашки нагріваються і збільшуються в обсязі в наслідок дифузії газу з крові, питома вага личинки зменшується, в наслідок чого личинка починає спливати. Стиснення пігментних клітин призводить до опускання личинки на глибину. Метод мікроскопії: темне поле + поляризація.
English: Hydrostatic apparatus of the larva of the Chaoborus. The photo shows large tracheal bubbles. They hold the larva in the water in a horizontal position and help regulate the depth of immersion. Bubbles are covered with dark pigment cells that can resize. If the cells expanded due to absorption of light, tracheal bubbles heat up and increase in volume in consequence of difusiy gas from the blood, the specific weight of larvae decreases, in consequence of which the larva begins to float up. The compression of pigment cells leads to the lowering of the larva to a depth of. Microscopy method: dark field + polarization.
