Greenhouse experiments were conducted to determine the suitability of common beans, Phaseolus vulgaris L., broad beans, Vicia fabae L., and read clover plants, Trifolium pratense L., for rearing and maintaining large numbers of two spotted spider mite, Tetranychus urticae Koch. P. vulgaris was the most suitable host for rearing T. urticae, but was the most susceptible to damage of heavy mite infestations. V. fabae supported about the same numbers of T. urticae as P. vulgaris and was more tolerant of heavy mite infestations. T. partense was the least suitable for rearing T. urticae, but was the most tolerant of heavy mite infestations. Results suggested that V. fabae is the most suitable host for rearing Tetranychus urticae in greenhouses
