Abstract

This study employed flow-through respirometry to measure the oxygen consumption rates ((V) over dot(O2)) of inactive male house crickets, Acheta domesticus L. (Orthoptera: Gryllidae), and to quantify the effects of body mass and adult age on standard metabolic rate (SMR). The (V) over dot(O2) increased with male body mass at a rate similar to thatfound in other studies of insect aerobic metabolism. The data reported in this study are combined with published data from other species ofOrthoptera to generate a consensus allometric relationship between SMR and body mass for the Order. In general, the Orthoptera expend 2-3 times the energy per unit of body mass when inactive as compared to other arthropods, such as tenebrionid beetles, ants and spiders. Possibleexplanations for this substantial difference are discussed. By contrast to body mass, mass-specific (V) over dot(O2) decreased with increasing male age. This age effect has previously been reported for mammalsbut is not well established for insects, and its implications for thepreference of cricket females for older mates is discussed. As energyexpended for metabolic maintenance comprises 78% of a male cricket's daily energy budget, changes in SMR may have a substantial effect on the energy available for reproduction.
