摘　　要：田间调查了不同生境条件茶园对茶蚜种群特征的影响。结果表明:小乔木茶园茶蚜分布在中层部位较多,数量大小依次为中层>上层>下层,但总个体数在3类茶园中相对较少;脱叶楹茶园茶蚜分布在上层部位较多,数量大小依次为上层>中层>下层,但总个体数在3类茶园中相对较多。3类茶园中茶蚜在不同季节间发生动态有显著差异;小乔木茶园和相思树茶园的茶蚜数量在春茶与夏茶期间发生较多,分别占56.05%、36.05%和31.46%、46.10%;托叶楹茶园的茶蚜数量在夏茶与秋茶期间发生较多,分别占41.17%和37.89%。由此可知生境条件改变对茶园茶蚜种群数量有较大影响。A field survey was conducted to study the effects of tea plantations with different landscape structures on the population characteristics of Toxoptera aurantii（Boyer）. The results showed that the number of aphids in tea plantation within small woodland was the least, but in the tea bush middle happens more, followed by middle〉upper〉 lower; the number of aphids in tea plantation within Acacia chinensis were much more than the other tea plantations, but in the tea bush upper happens more, followed by upper〉 middle〉 lower; there was a significant difference of aphid dynamics in the different seasons with three kinds of tea plantations. Tea plantation within small woodland and within Acacia confusa had more aphids during the spring and the summer tea, a total of 56.05%, 36.05% and 31.46%, 46.10%, respectively; tea plantation within small Acacia chinensis had more aphids during the summer and the autumn tea, and was 41.17% and 37.89%. Those results indicated that tea plantations within different landscape structure had significantly effect on aphid populations.
