[Method]The investigation on the distribution and damage of R. ferrugineus was conducted in Nanning City, Guangxi Province. Its transmit ways were chocked, light trapping experiment, combination of artificial and chemical control, and chemical control were conducted. [ Result] The investigation indicated that there had distribution of R. ferrugineus in 70% plant nurseries and the scenic areas in Nanning City. Among the planted Hemp palm plants, the damaged vari- eties were up to 80%. The output of palm seedlings which had carried with pests was the main approach for spread and damage of R. ferrugineus. It was effective and feasible to use frequently vibration trapping light to trap adults. Pesticides were sprayed on the bellmouth of host （ central leaf）, then aging leaf sheaths or agri- cultural film was used to strap tender leaf sheath in stalks, which could achieve the purpose of controlling R. femugineus. [ Conclusion ] The control strategies of R. femugineus should be focused on controlling seedlings and the plants with tree age less than ten year; the plants with long tree age and the tall plants should adopt selection control if it was necessary, and the integrated control should be implemented on the prevention measure.展开更多
