Abstrakt:	Background: The polyphagous predatory bug Orius strigicollis Poppius (Heteroptera: Anthocoridae) is an active predator used to control many insect pests of agricultural crops. Orius species are significantly affected by the type of food and temperature. Method: A study of O. strigicollis feeding on Plutella xylostella L. (Lepidoptera: Plutellidae) eggs in climate chambers at 28 and 32 °C, 70 ± 5% relative humidity, 16:8 photoperiod, was conducted to determine the effects of different temperatures on the predation activity, biological characteristics and demographic parameters of O. strigicollis . Twosex-MS Charts were used to determine the age-stages and characteristics of this species. Results: The results showed that the daily consumption of pre-adults on eggs of P. xylostella was highest at 28 °C, and at this temperature, there was a greater probability that O. strigicollis would survive to adulthood (42.5%) than at 32 °C (25.0%). It has also been found that at 28 °C there was a long oviposition period (9.38 days) and the greatest female fecundity (44.2 eggs/female) In addition to the highest life expectancy of O. strigicollis (16.96 days) at 28 °C, the intrinsic rate of increase (0.087 d -1 ) was also highest. According to our results, O. strigicollis has the potential to grow and develop on the eggs of P. xylostella at 28 °C and, therefore, could potentially be used as a biological control agent in integrated pest management (IPM) programs. Competing Interests: The authors declare there are no competing interests. (©2024 Ur Rehman et al.)
