Some of the life cycle parameters of the citrus red mite, Pamonychus citri (McGREGOR), were estimated by rearing experiments at constant temperatures of 12,16,20,24,28 and 32℃. The durations of egg stage and pre-adult stage, and the mean generation time (T) were 5.3,9.1 and 11.7,respectively, at 32℃. At 12℃, these values increased by about 6-7 times those at 32℃. Developmental zeros of the egg and pre-adult stages were 7.4 and 8.2℃, and total effective heat was 123 and 217 day-degrees, respectively. All of these parameters such as total fecundity, net reproductive rate (Ro) and intrinsic rate of natural increase (γ_m) were maximum at 24℃, and the values (in case of sex ration 7♀ : 3♂) were 42.6,28.3 and 0.171/day, respectively.
