- Structure of the thoracic spiracular valves and their contribution to unidirectional gas exchange in flying blowflies Calliphora vicina
Summary: External filter flaps and inner valves support a respiratory airflow through the thorax in flying blowflies by opening the valve flaps during wing upstroke and keeping the inner openings narrow.
- Discontinuous gas-exchange cycle characteristics are differentially affected by hydration state and energy metabolism in gregarious and solitary desert locusts
Summary: This study shows that haemolymph loss and energy metabolism combine to affect the ability of insects to maintain discontinuous gas exchange cycles under stressful conditions.
- Flight-motor-driven respiratory airflow increases tracheal oxygen to nearly atmospheric level in blowflies (Calliphora vicina)
Highlighted Article: Blowflies increase their tracheal oxygen concentration during flight above the resting level by a unidirectional autoventilatory airflow.
