Abstract

In order to effectively control the outbreak of Drupa and Drupella and protect the coral reef ecosystem, the biological characteristics, outbreak period, damage degree and causes of Drupa and Drupella were summarized. At the same time, based on the investigation and analysis of the South China Sea, the control measures are put forward. The results show that the main food of Drupa and Drupella is Acropora. Drupa and Drupella has the characteristics of small individual, long breeding cycle and clustering, and its outbreak seriously damages the coral reef ecosystem.
