Two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is one of the important pests of agricultural crops, which can cause severe damage on them. The polyphagous mirid Macrolophus pygmaeus Rambur (Heteroptera: Miridae) is one of the important biological control agents against various pests, including Two-spotted spider mite, T. urticae. Therefore, study of its capabilities may play an important role in the pat management programs. In this study, biological properties and life table statistics of M. pygmaeus were studied by feeding on T. urticae, T. urticae+Bee pollen and Bee pollen under laboratory conditions (25±1°C, 65±5 % RH and 16:8h L: D) with 60 replication. The geranium leaf Pelargonium hortorum served as oviposition substrate and the moisture source. Data analysis carried out based on age-stage two sex (TWOSEX-MSChart (version 2017)) life table analyzing program. The results showed the developmental time in nymphal stages which feed on T. urticae+Bee pollen, T. urticae and Bee pollen for males and females equal to 17.33 ± 0.11, 17.96 ± 0.07 and 19.53 ± 0.07, 17.95 ± 0.12, 18.74 ± 0.09 and 20.15 ± 0.17 days respectively. The longevity for males and females were estimated 24.1 ± 1.17, 21.8 ± 1.39, 21 ± 0.6 and 21.1 ± 1.05, 21.07 ± 1.24 and 19.3 ± 0.56 day respectively and the average number of oviposition were recorded 32.86 ± 5.20, 20.76 ± 2.07 and 26.1 ± 1.96. per female on three diets respectively, as well as intrinsic rate of increase (rm) calculated as 0.066 ± 0.006, 0.058 ± 0.004 and 0.055 ± 0.005 day-1. Additionally, finite rate of increase (λ) recorded 1.068 ± 0.006, 1.059 ± 0.004 and 1.057 ± 0.005 day-1 and net reproductive rate (R0) as 12.05 ± 2.77, 9.1 ± 3.61 and 8.1 ± 1.71 (eggs/individual) respectively. Furthermore, mean generation time (T) estimated as 37.57 ± 0.55, 38.33 ± 0.47 and 38.97 ± 0.31 days and gross reproduction rate (GRR) 18.26± 4.14, 12.59± 2.09 and 13.57± 2.35 (Eggs/individual) respectively. The results indicated the significant differences of diet on the incubation period, nymphal period, survival rate, reproduction rate and longevity of M. pygmeaus. Also the results showed that feeding on herbal and animal combined diet (T. urticae+Bee pollen) reduces nymphal longevity, increase productivity and longevity of adults compared to the two other treatments. According to the present results, the last mentioed food is more suitable prey for breeding of this predator and may improve conservation and the biological control potentials of the predator.
