BACKGROUND: Knowledge of the compatibility between spirodiclofen and the predator Oligota flavicornis is an important aspect for the management of spider mites. RESULTS: We used the age-stage, two-sex life table to assess the effects of spirodiclofen on the life history traits and population growth of O. flavicornis. At the maximum recommended concentration (60 mg a.i. L -1 ) and also at twice the maximum recommended dosage (120 mg a.i. L -1 ), the preadult stages of O. flavicornis were significantly lengthened, while the adult longevity and fecundity decreased significantly. The finite rate (?), intrinsic rate of increase (r), and net reproduction rate (R 0 ) decreased, while the mean generation time (T) was longer after both the 60 and 120 mg a.i. L -1 treatments than it was in the control and 30 mg a.i. L -1 treatments. Life expectancy and reproductive value were higher in the control and 30 mg a.i. L -1 treatment than in the 60 and 120 mg a.i. L -1 treatments; the two higher concentrations were detrimental to the development of O. flavicornis. CONCLUSION: A proper combination of the O. flavicornis and spirodiclofen to control the spider mite, while avoiding the side effect of spirodiclofen, could be achieved based on the knowledge of life tables. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry
