Keywords: damage of Polyphagotarsonemus latus on common bean Phaseolus vulgaris is characterized by deformation and curling up of newly formed leaves, leaf undersides turn purplish, and in severe attacks the whole leaf turns golden yellow, and pods are covered with wound tissue, the mite has a large host range and a short life cycle lasting 4-5 days, females lived an average of 15 days during which 45 eggs were laid on average, carbaryl controlled P. latus but caused a spider mite outbreak, Tetradifon (Tedion) controlled T. desertorum but gave poor control of P. latus, while dicofol controlled both species
