While conducting experiments on biological control of the twospotted spider mite. Tetranychus urticae Koch, on strawberry in Orange County (Oatman 1965. Oatman and McMurtry 1966. Oatman et al. 1967, 1968), specimens of the various mites present on the leaves Were kept for identification. Most of the material was collected in 1964, 1965, and 1966 from summer plantings of either ‘Shasta’ or ‘Torrey’ varieties. The strawberries were planted in late August and harvested from March through June of the following year before being diseed under prior to replanting in August. Although the soil is usually fumigated with a mixture of methyl bromide and chloropicrin prior to planting, the 1964–65 and 1965–66 plantings were not.
