蜘蛛对茶园害虫控制作用的研究

1981年以来，湖南省兰岭茶园开展了大面积以保护茶园蜘蛛为主的茶园害虫综合防治技术研究。近10年来未打化学农药，4年未施化学肥料。试验结果表明，这些措施不但使以蜘蛛为主的茶虫天敌的种类增多、种群数量上升，而且使茶园内主要害虫的种群数量逐年下降；茶叶内不含任何农药残毒，产品达到国家AA级绿色食品要求；经济效益得到成倍增加。

The Researches of Using Spiders to Control Insects in Tea Field

Integrated pest management(IPM) technique of protecting spiders (Araneae) to control pests in tea field had carried out in large scale in Lanling tea field,Hunan Province since 1981.Any chemical pesticide had been sprinkled in nearly ten years and no chemical fertilizer had been used in four years.The results showed that these measures not only could increase the number and species of the main natural enemy of tea pest such as spiders,but also could decrease the population quantity of the main pest in tea field year after year.Tea had not any residual toxicity of pesticide and products had reached the green food require of AA level.Economic benefit had increased several times.
