Orius strigicollis (Poppius) was reared on the modification of rearing media for Tetrastichus sp. at $28^{circ}C$, 18L: 6D, and $50-60\%$ RH, in which meat diets were used for partial replacements of insect source of the artificial diets. Life history traits of the predacious bug fed on the diet were measured. Nymphal development period and mortality rate of O. strigicollis were about 14 days and $31.5\%$ (survival rate: $68.5\%$), respectively. The female bug produced average of 82.5 eggs during its oviposition period of 18 days when artificial oviposition substrate was provided. The fecundity was shown to be superior compared with previous researches on the species fed natural preys as a food.
