Abstract
The biological control of Panonychus ulmi, Tetranychus urticae on apples was studied in apple orchards in Switzerland during 1986-88. The predatory mites Typhlodromus pyri and Amblyseius andersoni were released in some orchards and appeared naturally in others. Techniques for sampling predatory and phytophagous mite populations are described
