Laboratory population life tables of Amblyseius orientalis Ehara were constructed at three different constant temperatures and one natural variable temperature. The intrinsic rate of natural increase (r_m), net reproductive rate (R_o) and the finite rate of increase (λ) reached maximum values at the constant temperature of 25°C and 85% RH: r_m= 0.3246, R₀ = 42.93 and λ = 1.3835. At natural variable temperatures with an average of 26.2°C and 85%RH, its mean generation time (T) was the longest: T = 14.75. It was concluded that temperatures from 25°C to 26°C and relative humidity of 85% are the most suitable conditions for the mass-production of Amblyseius orientalis.
