油茶不同品种（系）对茶黄蓟马的抗性研究

茶黄蓟马又称茶黄硬蓟马（Scirtothrips dorsalis Hood）,属缨翅目蓟马科（Thysanoptera：Thripidae）[1],在国内主要分布于海南、广东、广西、云南、浙江、江苏、安徽、福建、台湾、河南等省区;国外主要分布于日本、印度、马来西亚、巴基斯坦、印度尼西亚、澳大利亚等国家[2-3]。主要寄主有茶叶（Camellia sinensis O.Ktze）、葡萄（Vitis vinifera L.）、芒果（Mangifera indica L.）、花生（Arachis hypogaea L.）、...

[ Objective ] To understand the resistance of oil tea to Scirtothrips dorsalis and analyse the mechanism. [ Method ] The population densities of S. dorsalis on seven varieties of oil tea in field were investigated, the surviv- al rates were tested by feeding them with the tender leaf of the seven varieties of oil tea in laboratory, and the fuzz distribution characteristics of the tender shoots were recorded respectively. [ Result ] The results showed that there were significant differences in mean population density of S. dorsalis among these varieties of oil tea in the field; however, the average survival rate of S. dorsalis did not show significant difference in lab. [ Conclusion] Based on correlation analysis it was showed that the resistance of oil tea to S. dorsalis did not come from its own chemicals, but might mainly due to the distribution of fuzz on leaf surface.
