Abstract Aphelinus albipodus Hayat and Fatima (Hymenoptera: Aphelinidae) is a parasitoid wasp that uses aphids as hosts and is a candidate for biological control of aphids that infest commercially important crops. To determine the ideal conditions for large-scale reproduction of A. albipodus, a leaf disc method was used to compare the life history of A. albipodus parasitizing Aphis glycines L. (Homoptera: Aphididae) at 20, 24, 28 and 32 °C. The results were analyzed using the age-stage, two-sex life table and showed that the developmental duration and longevity of A. albipodus decreased significantly with increasing temperature. The mean generation time (T) also decreased as the temperature increased. In contrast, the intrinsic rate of increase (r) of A. albipodus increased with rising temperatures. The net reproductive rate (R $_{0}$) showed a more complicated pattern, first increasing in higher temperatures and then dropping off at the highest temperature. We employed bootstrap techniques for estimating the variance and standard error of the population parameters. The r increased significantly as the temperature increased, and R $_{0}$ at 28 °C was significantly higher than at 32 °C. Overall, our results showed that 28 °C was the most suitable temperature for reproduction of A. albipodus with A. glycines as the host.
