Abstract
Thysanogyna limbata is a pest on the landscape plant Firmiana platanifolia. In this study, we evaluated the control efficacy of twelve insecticides and five common natural enemies to T. limbata. The results showed that the control efficacy of thiamethoxam and imidacloprid to T. limbata was much better than other insecticides. For the three application methods evaluated (spraying, injection, and root-irrigation), the spraying method should be avoided and the injection performed better. If conditions permitted, root-irrigation method could be used as a supplementary method. Among the five natural enemies, Chrysoperla sinica and Lemnia saucia had the best control effect on T. limbata, which could replace insecticide in the long-term control effect. Therefore, C. sinica and L. saucia could be used as safe and environment-friendly pattern to prevent T. limbata in the medium- and long-term in the garden, whereas injection of thiamethoxam and imidacloprid could be used as a short-term and rapid treatment.
