Abstract
紅葉蟎(Tetranychus cinnabarinus Boisduval）為本省南部木瓜最普遞之害蟎。
全年均有發生，於乾旱季節(10-4月)發生最嚴重。發現其天敵有八種，以羅氏小黑瓢蟲(Stethorus loi)，鄭氏小黑瓢蟲(Stethorus chengi)，小黑隱翅蟲（Oligota oviformis)，長毛捕植蟎(Amblyseius longispinosus)等出現頻度較高。殺蟎劑對木瓜植株常生藥害。田間噴射百蟎克(Binapacryl) 50%可濕性粉劑稀釋2,000倍藥液（用藥量0.65kg ai/ha），對防治本葉蝸具優異效果。
Carmine spider mite (Teiranychus cinnabarinus Boisduval), one of the destructive pests on papaya in the southern part of Taiwan, occurs all year round, especially during the dry season (from October to April). Eight species of natural enemies of the
carmine spider mite were recorded. Among these, Slethorus loi Sasaji, Stethorus chengi Sasaji, Oligota ovifornzis Casey and Amblyselus longispinosus Evans appeared frequently erough to check the population of this mite. High concentrations of tested miticides induced phytotoxicfty. Application of Binapacryl 50% W. P. at the concentration of 0.025% (0.65Kg ai/ha) resulted in satisfactory controls of the carmine spider mite.
