Phenacoccus parvus Morrison, a polyphagous pest originally from South America,is widely distributed in tropical areas. This mealybug had previously been recorded in Hong Kong and Taiwan but not on the Chinese mainland. However, it was found at two sites in Yunnan Province, on Capsicum frutescens in Jinghong in 2008 and Lantana camara in Mengzi in 2013. These are first records of P. parvus on China's Mainland. This paper provides a brief introduction of the morphological identification characteristics of this species, its distribution, host plants, biology and economic importance.
