The presence of DGE in insects and some other arthropod taxa is most often considered as an adaptation to reduce respiratory water loss rate. 32–34 In DGE during C and F phases, the spiracles are closed or flutter and no outward movement of gas molecules (including H2O) can occur. 35–37 The water vapor leaves the insect body through the cuticle or spiracles. In most insect species studied, spiracular water loss makes up approximately 10% of all water loss. 38 This seems to be an inconsiderable amount, which still may prove to be critical in conditions where water is a limiting factor. 39–42 There is proof that the varying patterns of DGE contribute differently to the rate of water loss. 43 However, in some experiments where the insects were forced to open or close the spiracles because of hyperoxic or hypoxic conditions, the presence or absence of DGE has been shown not to affect water loss rate. 33,44,45
In many studies, only the total water loss has been estimated. The gravimetrical method of weighing the insect before and after the experiment does not allow separation of the gas-exchange patterns and phases within DGE. 23,43 Modern gas analyzers (eg, LiCor 6262 or 7000, LiCor, Lincoln, NE, USA) allow simultaneous recording of different gases, which enable the measurement of water loss during the open and C+F phases of DGE. 24,46–48 At that time, the only H2O detected is evaporated through the cuticle. During the O phase of DGE, the additive peak indicates H2O emergence through the spiracles.
