Values shown are means ± S.E.M. N is given in parentheses.
Burst duty is the percentage of the total cycle dedicated to the burst. Vr is the membrane potential recorded at rest. The means for the molting and intermolt larvae were not significantly different for any of the variables tested (P>0.05, unpaired t-test).
