Six species of spider mites are associated with almond trees in California's Central Valley. The lack of economical and reliable sampling techniques has hampered not only research on these mites but also the grower's ability to estimate control status or population density in a minimum amount of time. Three of the six spider mite (tetrany-chid) species — the European red mite, brown almond mite, and citrus red mite — are occasionally abundant enough to require chemical treatment. European red mite and brown almond mite are most often found in the northern and central Valley, and the citrus red mite, in citrus-producing areas of the southeastern Valley.
