Tick survival upon exposure to sublethal doses of chlorpyrifos. Parthenogenetic larva (a), nymph (b), adult (c) and bisexual adult (d) ticks were exposed to sublethal doses of chlorpyrifos for 48 h. Ticks lying on their backs that could not turn over were considered dead. *P < 0.05: significantly different by Welch’s t-test as compared to the EGFP knockdown of the same acaricide concentration
