假眼小绿叶蝉(Empoasca vitis Gothe)是我国茶区分布最广、为害最重的一种茶树害虫。该虫以成虫和若虫吸取茶树汁液为害,干扰茶树营养物质的正常输送,导致茶树芽叶失水、生长迟缓、焦边、焦叶,造成茶叶减产。全年以夏秋茶受害最重,一般受假眼小绿叶蝉为害可使夏秋茶减产10%～15%,为害严重年份减产可高达50%以上。此外,假眼小绿叶蝉为害后的芽叶,在加工过程中易断碎,易产生烟焦味,对茶叶品质亦有严重的影响。
Empoasca vitis Gothe is one of the most widely distributed tea tree pests in our country. The worm to adult and nymphs draw tea juice damage, interfere with the normal transport of tea nutrients, leading to tea tree buds dehydration, growth retardation, coke edge, coke leaves, resulting in reduced production of tea. Throughout the year, summer and autumn tea suffer the most. Generally, the harm caused by the small green leafhopper can reduce the yield of summer and autumn tea by 10% -15% and reduce the yield by more than 50% in the serious year. In addition, the green leafhopper pest damage after the shoots, broken easily in the processing process, easy to produce smoke burning taste, the quality of tea also have a serious impact.
