Summary:[ Objectives ] The paper investigated the occurrence and damage of thrips on winter vegetable cowpea in Sanya City, to summarize prediction method and control measures against the insect pest. [ Methods] Prediction through analogy suggested that cowpea could be damaged by thrips throughout the entire growth period. [Results] The peak occurrence and damage period of thrips was after transplanting of cowpea from December to early March in the following year. The occurrence of thrips was severe in the case of high temperature and drought, or was light when encountering rainy season. [ Conclusions ] Using fivepoint sampling method, blue boards were hanged up for monitoring （five pieces each point, specifieation 25 cm × 30 cm）. When the number of thrips on blue board reached 10 specimen/piece, it was the optimal control period of thrips, and different prevention and control measures could be adopted according to the specifi growth stages of cowpea.
