مقارنة ثلاثة أصناف من الفاصولياء المتسلقة كعائل نباتي للحلم الأحمر ذي البقعتين (Tetranychus urticae Koch)‎ و مفترسه Phytoseiulus persimilis Athias-Henroit

Abstract EN

Tetranychus urticae Koch is considered an important host for the predatory mite Phytoseiulus persimilis Athias-Henroit, in biological control programs.

It is necessary for rearing T.

urticae on a suitable host plant in order to obtain considerable numbers of T.

urticae in a short period of time.

This study aimed to investigate the change in numbers of both T.

urticae and P.

persimilis, on three cultivars of climbing bean: Kentucky wonder white, Fatima, and Purple Queen to determine the most suitable cultivar for rearing P.

persimilis, and the most suitable host for T.

urticae, and employ those cultivars for predator rearing in biological control programs.

Results obtained showed that Kentucky wonder white was the most suitable host plant for T.

urticae in biological control programs, and Fatima was the most suitable for rearing the predator mite P.

persimilis
