Since we need to find that whether there is a statistically correlation between the body mass and metabolic rate of Manduca sexta, Regression test was used to analyze our data. The independent variable is the metabolic rate and the dependent variable is body mass.

3. Result The body mass of caterpillar (Manduca sexta) varied from 0.25g to 1.55g. The measured temperature inside of the chamber varied in different caterpillar and ranged from 22.0°C to 23.1°C. The volume of O2 consumption in 15 min ranged from 0.0mL to 0.60mL. The metabolic rate value (mL/min) was 0 to 0.04. From the Regression test, the P value is 0.079, coefficient value is 0.019 and 95% confidence interval value is from -0.0033 to 0.0405. It can be seen the correlation between body mass of Manduca sexta and its metabolic rate based on the graph (Fig.1) Figure 1: The correlation between body mass of Manduca sexta and its metabolic rate 4.
