In the laboratory, females of Typhodromus tiliae Oudms., T.(N.) rhenanus Oudms., T. finlandicus Oudms., T. fallacis (Garm.), T. corticis Herb., and Phytoseius macropilis (Oudms.) were given various stages of the phytophagous mites Panonychus ulmi (Koch), Bryobia arborea M. & A., and Tetranychus telarius (L.), and Vasates schlechtendali (Nal.) to determine their ranges of feeding. The influence of these prey species on growth of phytoseiids and their ability to oviposit was not determined.
