Abstract : Three species of mite pests are reported for the first time from the Philippines, namely, Steneotarsonemus pallidus [Phytonemus pallidus], Eotetranychus lewisi, and Tetranychus urticae. All three species infest strawberries in Benguet province, while E. lewisi also infests poinsettia in Benguet. T. urticae is more widespread on roses and chrysanthemums. The specimens originated from commercial gardens in the provinces of Benguet, Laguna, and Cavite. The diagnostic characteristics of these species are presented, specimens are illustrated, and notes on the damage caused by these mite pests and their associated predators are given. New plant host records are provided for 14 other species of phytophagous mites and new island records for four species. Notable among these new pest records are Oligonychus biharensis on cassava from Isabela province, O. coffeae on mango from Guimaras Island, and Panonychus citri on citrus from Davao City.
