The ramie moth is one of the main pests in the ramie growing stage. As the global climate warms, its occurrence has undergone great changes. From 2009 to 2012, we conducted a follow-up investigation on the occurrence of the ramie (Lycopershelus californicum) in the main areas of ramie. The results showed that the annual occurrence of ramie in the Yangtze River valley changed from the past 3 generations to the present 4 generations. In the meantime, the reason why ramie nauplii was changed and the control measures of ramie nauplii were discussed in this paper, in order to provide references for the prevention and control of ramie nauplii.
