Abstract

A gas analysis system is described for the measurement of the metabolic activity of honeybees. With this, respiration of individual or groups of bees can be continuously recorded in both laboratory and field conditions with a sensitivity of about ± 0.15 mg CO2 h-1 in the range of 0 - 15 mg CO2 h-1 for one individual bee. Replicates can be measured at the same time by use of a sequencial gas sampling unit which allows statistical treatment of data in an interfaced computer. To exemplify the utility of the apparatus, preliminary test results of the diurnal respiratory cycle of a single bee and the effect of dirnethoate on the respiration of groups of bees are presented.
