Bio-insecticidal effects of seven Chinese medicinal herbs on mortality, fecundity, developmental periods and life table parameters of the grape phylloxera were investigated. In an excised root bioassay experiment aqueous extracts from seven Chinese medicinal herbs increased grape phylloxera first instar mortality (26.00–38.50%) compared to other instars. The intrinsic rate of increase (rm), finite rate of increase (λ), fecundity rate and net reproductive rate (R0) were significantly reduced by A. bidentata, A. tataricus, O. basilicum, P. frutescens and N. cataria. In a glasshouse pot trial, eggs, nymphs, adults and total population were significantly reduced before population establishment compared to those after its population established, by A. bidentata, A. tataricus and O. basilicum. Overall, A. bidentata, A. tataricus and O. basilicum can be used to suppress all life-stages of grape phylloxera.
