Abstract
The seasonal development and distribution of populations of Amblyseius scyphus Schuster & Pritchard, a natural predator of Oligonychus pratensis (Banks), was studied on sorghum in west Texas. Summer populations of A. scyphus reached a peak of 1.7 mites/plant before harvest and infested up to 54% of the sampled plants. Females of A. scyphus were apparently in reproductive diapause during the winter; at first they were located under the leaf-sheaths along the whole stem of dead sorghum plants, but by March they were concentrated at the base of each stem. In April A. scyphus migrated from the dead sorghum stalks to young plants of triticale and Johnson grass [Sorghum halepense] of the current year
