Fig. 8. Effects of repeated exposure of Manse-AT on the rate of oscillation of semi-isolated adult P. unipuncta virgin day-3 female VNC. Manse-AT was serially applied at approximately the EC₅₀ value at 0, 2, 4 and 6 min. Data are expressed as percentage increase in resting rate and values are means ± S.E.M. (N=5 or more samples). ^*Significant increase from resting rate (P<0.05).
