Using GC-MS, we studied the time course of Tetranychus urticae-induced kidney bean plant volatile production during the period from foundation to collapse of the T.urticae colony. The density of T.urticae females showed a unimodal curve, which was followed by the production of T.urticae-induced plant volatiles. The intensity of the olfactory response of the predatory mite Phytoseiulus persimilis to the induced volatiles in a Y-tube olfactometer correlated with the amount of volatiles per plant. In the period before the increase of the second generation of female T.urticae, the infested plant did not attract predatory mites. Such a period can be considered to constitute a temporary enemyfree period for T.urticae.
