Phyllocoptes adalius, because of its high potential to economic damage, is an important pest of Rosacea. Phytoseiid mites are the most important natural enemies of pest mites to be considered in integrated pest management. Amblyseius swirskii is an omnivorous mite that feeds on many species of small arthropods as well as pollen grains. Life table gives the most comprehensive description on the survival, stage differentiation and reproduction of a population and is thus the most important basis of population ecology and pest management. In this study, the life parameters were conducted under laboratory conditions at 25± 5˚C, 70-80% RH and photoperiod of 16:8 (L:D), P. adalius was used as prey. To initiate experiments, 50 cohort eggs were used as a fertility and life table with a follow-up cohort to the last individual drawn. The intrinsic rate of increase (rm) the net reproduction rate (R0), mean generation time (T) and finite rate of increase (λ) was estimated 0.172 day -1, 12.59 offspring/female, 14.72 days and 1.18 day -1 respectively. In conclusion, results showed that A. swirskii would be able to develop at temperatures range of 20–25°C feeding on P. adalius and its role to achieve efficient control of on P. adalius management are discussed.
