【Aim】 The fig wax scale Ceroplastes rusci (Linnaeus) (Hemiptera: Coccidae: Ceroplastes) is a cosmopolitan pest, native to Africa that has not been systematically investigated since it was introduced to China in 2012. In this study, we investigated its occurrence and damage in the Yunnan Province, which can provide useful information for its monitoring and management. 【Method】 The distribution, host, and biological characteristics of C. rusci were investigated from October 2016 to October 2021 in 113 towns across 67 counties in the Yunnan Province. 【Result】 Our survey identified 17 C. rusci localities, which were distributed in 14 counties of Yunnan Province. C. rusci were found in 18 plant species, representing 13 genera from eight families. Of these, 11 were not previously reported as host plants in China, including Ficus carica, Mangifera indica, Olea europaea, Cocos sp., and Elaeis guineensis, five important economic tree species. Multiple species of plants belonging to Arecaceae and Ficus belonging to Moraceae were damaged, with Chrysalidocarpus lutescens being the most common. C. rusci fed on leaves (usually the upper surface) and twigs and had the habit of spread from leaves to twigs as they matured. 【Conclusion】 C. rusci showed scattered distribution in Yunnan Province, but was more common in southern Yunnan. The general damage caused by this species was not severe; however, the damage to the figs was severe. The continued spread of this pest is high and warrants further investigation.
