“…The gas analyzer and flow-through respirometer were calibrated by means of calibration gases (Trägergase, VEB, Saxon Junkalor GmbH, Dessau) with gas injection (see also Kuusik et al 2002;Mänd et al 2006). When the respirometry was carried out, the insect chamber was perfused with dry (5-7 % RH) CO 2 -free air, produced by passing air over Drierite (W. A. Hammond Drierite Co. Ltd, Xenia, Ohio) and soda-lime granules at a flow rate of 60 ml min .…”

Measures of repeatability are essential for understanding behavioral consistency and individual differences in behavior, i.e. animal personalities. We studied antipredator responses of the yellow mealworm beetle (Tenebrio molitor) and performed behavioral tests in plastic containers representing a typical laboratory environment of T. molitor. Behavioral tests were repeated in Eppendorf test tubes where we also measured resting metabolic rate (RMR). Results show that the response latency to a threatening/startling stimulus, and the total time spent in the state of tonic immobility, correlated across the tests. The behavioral responses were repeatable and RMR covaried phenotypically with personality: we found a negative correlation between response latency time and time spent immobile, a positive correlation between response latency and RMR, and a negative correlation between RMR and total time spent immobile. These correlations were also similar across trials performed in the Eppendorf test tubes and the plastic containers.

“…The light from the IR-diode was modulated by the contractions of the heart and skeletal muscles. The level of output voltage reflected the vigour of the muscular contractions of the insect (see Hetz, 1994;Hetz et al, 1999;Metspalu et al, 2001Metspalu et al, , 2002Kuusik et al, 2002). Abdominal contractions resulted in downward spikes, muscular relaxations were directed upward.…”

Discontinuous gas exchange cycles and active ventilation in pupae of the bumblebee Bombus terrestris

-Discontinuous release of CO 2 (bursts) or discontinuous gas exchange cycles (DGC), metabolic rate (MR) and ventilation movements were simultaneously recorded from the pupae of the bumblebee Bombus terrestris by means of an electrolytic respirometer and an infrared gas analyser (IRGA) combined with an infrared actograph (IRA). After recovering from stress, the early stage pupae showed irregular continuous respiration, mid-stage pupae displayed regular DGC. The bursts of CO 2 release tended to coincide with abdominal contractions. In late stage pupae all bursts of CO 2 were associated with active ventilation. During interburst periods, spikes appeared on the respirograms interpreted as micro-cycles of passive suction ventilation (PSV). After removal from their cocoons, the pupae exhibited frequent periods of muscular activity due to stress. Water loss of pupae inside cocoons was significantly less than that from pupae without cocoons. Bombus terrestris L. / passive suction ventilation / standard metabolic rate / respirometry
