为了保护和利用天敌综合防治茶园害虫,首先,比较“平阳特早”茶园季节间害虫及其天敌的种群差异,结果表明,2010年春夏与秋冬之间,黑刺粉虱、茶叶甲、异色瓢虫、三突花蟹蛛、鳞纹肖蛸、粽管巢蛛、草间小黑蛛、斜纹猫蛛、龟纹瓢虫和八斑球腹蛛的t值均小于t0.05(2.13),差异不显著.并采用灰色系统和生态位分析法,对2010年春夏季茶园2种害虫与其天敌在数量、时间、空间等方面关系进行分析,2010年春夏季黑刺粉虱的主要天敌是鳞纹肖蛸、三突花蟹蛛和八斑球腹蛛;茶叶甲的主要天敌是龟纹瓢虫、异色瓢虫和草间小黑蛛;2010年秋冬季黑刺粉虱的主要天敌是鳞纹肖蛸、三突花蟹蛛和斜纹猫蛛.茶叶甲的是异色瓢虫、三突花蟹蛛和龟纹瓢虫.黑刺粉虱(2010年4月24日)的种群聚集均数!大于2,其聚集是本身特性造成的,2个时间段所有天敌的!值都小于2,其聚集是环境中某一因素所致.
In order to protect and utilize natural enemies to prevent and control tea garden pests, firstly, the differences in the population differences between pests and their natural enemies during the “Pingyang special early” tea garden season were compared. The results showed that in the spring and summer 2010, autumn and winter, , Heterochromatic ladybugs, trichotoma crab spider, squamous Zhaxiao, dumpling tube nest spider, grass black spider, twill cat spider, tortoise ladybug and eight-spot ball spider spider t values were less than t0.05 (2.13), the difference was insignificant.Analysis of the relationship between quantity, time and space of two kinds of pests and their natural enemies in spring and summer of 2010 by using the gray system and niche analysis, the main natural enemies of whitefly, Is the squamous Shaddock, the three Protruding crab spider and eight-spot ball spider spider; Tea A’s main natural enemies are Propylaea japonica, Harmonia axyridis and grass black spider; autumn and winter 2010 black spider whitefly’s main natural enemies Is a squamous Shaddock, the three Prothalia crab spider and twill cat spider.Tea A is the color ladybug, three Prothalia crab spider and tortoise ladybug. Blackthorn whitefly (April 24, 2010) of the population Aggregate mean! Greater than 2, its aggregation is caused by its own characteristics, 2 time period all the natural enemies! Values ?? are less than 2, the aggregation is a certain environment Su due.
