Abstract

Phytoseiuius persimilis was released to control the two-spotted spider mite, Tetranychus urticae, in field raspberries at Agassiz, B.C. The mite predators became established and responded numerically to the prey in the treatment plots. For a period of 8 weeks after release, the numbers of T. urticae were consistently lower in the treatment plots than in the controls. Differences in numbers of T. urticae between the treatments and the controls were significant on two dates.

Key words: Tetranychus urticae; Phytoseiulus persimilis; Rubus idaeus; biological control; Fraser Valley
