... during simultaneous measurements of CO 2 emission from the anterior mesothoracic spiracles and posterior body, which included the subelytral spiracles. However, when we sampled air directly from inside the subelytral cavity, we discovered that this pattern was reversed. A discontinuous gas exchange cycle...

... the subelytral cavity, of a large apterous beetle, Circellium bacchus . Flow-through respirometry revealed a marked discontinuous gas-exchange cycle(DGC) pattern from the anterior half of the body. Very little CO 2 was released from the posterior body, where the DGC was not apparent. Labelled air was shown...
