Title: Chemically mediated arrestment of the predaceous mite Phytoseiulus persimilis by extracts of Tetranychus evansi and Tetranychus urticale.

Keywords: Phytoseiid
Description: 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.
