Abstract
Biological aspects, thermal requirement, predation rate and life table parameters of the phytoseiid predatory mite Euseius scutalis (A.– H.) fed on nymphs of Tetranychus urticae Koch was determined at four temperature degrees, 15, 20, 25 and 30 °C. The total developmental durations of female was correlated negatively with increasing temperature. Minimum developmental thresholds (To) of egg, larva, protonymph, deutonymph, total immature stages and life cycle of E. scutalis female averaged, 4.26, 10.98, 6.90, 1.20, 2.49 and 2.89; respectively. On the other hand E. scutalis female required 208.33 DD to reach adulthood. The net rate of natural increase (rm) was 0.008, 0.126, 0.166 and 0.193, whereas the finite rate of increase (erm) averaged 1.092, 1.134, 1.181 and 1.213 at 15, 20, 25 and 30 o C; respectively.
