Behavior of predatory mites in Y-tube olfactometer. Attraction of the predatory mite P. persimilis to the volatiles emitted from plants treated with T. urticae and B. tabaci (A) or T. urticae and SA (B), when volatiles from T. urticae-infested plants were offered as an alternative. (A) Effect of whitefly density on predatory mite behavior for three different infestation sequences of T. urticae and B. tabaci (B) Effect of SA dose on predatory mite behavior for three different sequences for T. urticae infestation and SA treatment. P. persimilis responses are presented as numbers of P. persimilis that chose for the treated plants (plus whitefly or SA) divided by the total number of responding P. persimilis (n = 80). Data points marked with an asterisk indicate significant differences from a 50:50 distribution (binomial test; *, P < 0.05). WF, whitefly B. tabaci; mite, T. urticae.
