ARE THE RESPIRATION RATES OF LARVAE AND ADULTS DIFFERENT?
JENNIFER TILLISS, CHRIS, TIERNEY, SARAH CU BOULDER In this experiment we tested whether or not the respiration rates of darkling beetles and mealworms were significantly different. The basis for this experiment stemmed from out observations that the darkling beetles were more physically active than the mealworms. We hypothesized that the respiration rate of adult darkling beetles would be significantly greater than the mealworms due to increased activity of the beetles. We tested the respiration rates of approx. equal masses of darlking beetles and mealworms by hooking them up to the computer in a gas sensor chamber and measuring CO2 levels in ppm. We measured the CO2 in an empty chamber for control and adjusted our means of respiration rates for the organisms from the CO2 consumption of the control. The respiration rate in adult darkling beetles was significantly different (p<.05) (greater) than that of mealworms. Our results were consistent with our hypothesis, therefore; we fail to
