【Background】Opisina arenosella Walker is an important pest on palm plants. The species is a severe pest in India and Sri Lanka; it has recently invaded Thailand. 【Method】Based on collected information about biology, ecology and the distbirution of O.arenosella, this paper presents its potential range in China. Invasion risk and consequences were also analyzed. 【Result】O.arenosella larvae usually have five instars and feed on the under surface of palm leaves. The egg stage lasts on average five days, larval stage lasts on average 42 days, pupae stage lasts on average 12 days, and a female lays on average 137 eggs. Areas with palms in south of China are potentially suitable distribution areas for O.arenosella as its phenology is similar to South and Southeastern Asia; Introduction and spread risk aspect: The flight ability of the adult and international trade, particularly with Association of Southeast Asian Nations (ASEAN) could enhance the pest entry possibilities; An eventual invasion of O.arenosella would damage coconut palms (Cocos nucifera L.), causing losses in palmbased industries, reduce the income of local residents and have a negative effect on local ecology. 【Conclusion and significance】Risk analysis of O.arenosella showed the pest might invade China and quarantine measures should be introduced for pest risk management. Biological control options should be explored.
