Pseudococcus jackbeardsleyi Gimpel & Miller, native to the Neotropical region, is a new invasive species on the Chinese mainland. The species harms fruits, vegetables, ornamental plants and food crops. P. jackbeardsleyi was first detected on Luffa cylindrica L. in Ledong, Hainan, China, in 2012. About a half year later, it was found on bonsai-trained individuals of Ficus microcarpa originating from Guangdong or Fujian Province, in Urumchi, Xinjiang, China. P. jackbeardsleyi has a wide range of host plants and can damage more than 200 plant species belonging to 50 families. Furthermore, this mealybug species is easily carried away via inter-regional and international trade of agricultural products, which make it a potential threat to the production of agriculture and forestry industry in China. In the present paper, the geographical distribution, biological and ecological characteristics, diffusion trend, as well as management measures of P. jackbeardsleyi were described.
