...Bryan C. Rourke ABSTRACT The importance of respiratory patterns and the physical properties of cuticular lipids to insect water balance were investigated in natural populations of the grasshopper Melanoplus sanguinipes . I specifically test the hypotheses that patterns of discontinuous ventilation...

...Jon F. Harrison; Neil F. Hadley; Michael C. Quinlan ABSTRACT Many insects ventilate discontinuously when quiescent, exhibiting prolonged periods during which little or no gas exchange occurs. We investigated the consequences of discontinuous ventilation (DV) on haemolymph acid–base status...

... Camponotus vicinus discontinuous ventilation hypoxia metabolic rate Discontinuous external gas exchange is now known to occur in many adult insects, as well as in the diapausing lepidopteran pupae in which it was first discovered ( Kestler, 1978 , 1980 , 1985 ; Lighton, 1988 a , b ; Lighton...

...John R. B. Lighton; Dana A. Garrigan; Frances D. Duncan; Robert A. Johnson ABSTRACT It has been suggested that the discontinuous ventilation cycle (DVC) observed in many insects, including all ants described to date, is an adaptation to reduce respiratory water loss. To test this hypothesis...

...John R. B. Lighton; Barry G. Lovegrove ABSTRACT It is known that many insects emit CO 2 in widely spaced ‘bursts’ or discontinuous ventilation events, usually characterized by active abdominal ventilation. We describe the discontinuous CO 2 emission characteristics of the honeybee (Apis mellifera...
