Abstract
Control of red spider mite (Tetranychus urticae) in blackcurrants is increasingly difficult because of resistance to approved acaricides and poor underleaf cover with pesticides in full canopied crops.
Successful use of the predatory mite, Phytoseiulus persimilis, in strawberries in the UK has encouraged commercial blackcurrant growers to use biological control for this pest.
This paper describes the successful biological control of red spider mite on 20 acres of Ben Lomond, having introduced Phytoseiulus persimilis at a ratio of 1:560 (Phytoseiulus to red spider mite) in early August 1991. Control was achieved within 46 days of the application.
