Cyclic gas exchange in the giant burrowing cockroach, Macropanesthia rhinoceros : Effect of oxygen tension and temperature

Woodman, James; Cooper, Paul; Haritos, Victoria S


The giant burrowing cockroach, Macropanesthia rhinoceros, is endemic to north-eastern Australia and excavates a permanent burrow up to 1 m deep into soil. Using flow-through respirometry, we investigated gas exchange and water loss at three different oxygen tensions (21%, 10% and 2% at 20 °C) and temperatures (10, 20 and 30 °C at 21% oxygen). M. rhinoceros employ cyclic gas exchange (CGE) making the species by far the largest insect known to engage in discontinuous ventilation. CGE featured...[Show more]
