Chemically mediated arrestment of the predaceous mite Phytoseiulus persimilis by extracts of Tetranychus evansi and Tetranychus urticale.
Since Tetranychus evansi Baker and Pritchard had been observed to be unfavorable prey for several species of phytoseiid mite predators, a study was conducted to determine the possible existence of an allomone produced by this species against Phytoseiulus persimilis Athias-Henriot. Instead, P. persimilis was strongly arrested by extracts of eggs adult and, especially, webbing plus excreta of T. evansi. Methanol extracts of Tetranychus urticae (Koch) showed a stronger arrestment than extracts of T. evansi.
