The results showed that the numbers of S. furcifera choosing to feed and lay eggs on rice treated with n-hexane and dichloromethane extracts of star anise were both decreased, compared with on the control, and the number of eggs on rice plants treated with n-hexane and dichloromethane extracts was only 31.5% and 40.2% of that on the control, respectively. The amount of honeydew secreted by S. furcifera feeding on rice treated with n-hexane and dichloromethane extracts of star anise was also highly significantly reduced, only 59.61% and 48.71% of that on the control, respectively. The two extracts showed a satisfactory insecticidal activity to S. furcifera, with a half lethal concentration (LC50) of 0.59 μL/mL and 0.46 μL/mL, respectively, 72 h after treatment. Both extracts had an inhibitory activity towards acetylcholinesterase of S. furcifera, with a half inhibition concentration of 1.33 μL/mL and 1.13 μL/mL, respectively. It indicated that there were some bioactive substances in star anise for behavior regulation and insecticidal activity against S. furcifera, displaying a potential value for the prevention and control of S. furcifera in the field. keywords:Illicium verum  Sogatella furcifera  biological activity  acetylcholinesterase View Full Text  View/Add Comment  Download reader
