油茶(Camellia oleifera)是中国亚热带地区重要的经济林树种之一,现已大面积栽培,但油茶害虫一直未受到充分关注。本研究系统调查了浙江省衢州地区灯下油茶害虫和天敌昆虫的种类,分析了其多样性及种群季节动态。结果表明:在衢州地区灯下油茶害虫共有103种,隶属于6目33科81属;2012—2013年,共诱集各类油茶害虫41521头,以食叶害虫为主;油茶害虫的种类及种群数量季节变化明显受到气候条件、油茶生育期和茶果采摘的影响;5—9月为油茶害虫活动高峰期,4月和10月是过渡期,油茶害虫与天敌均由越冬转入活动或由活动转入越冬;黑光灯对油茶害虫天敌有一定的诱集作用,共诱集天敌昆虫21种983头。本研究结果为油茶害虫的综合治理提供了科学依据。
Camellia oleifera (Camellia oleifera) is one of the most important economic tree species in the subtropical region of China. Now it has been cultivated in large area, but Camellia oleifera has not received enough attention. This study systematically investigated the species of pests and natural enemy insects of Camellia oleifera in Lanzhou, Zhejiang Province, China, and analyzed their diversity and seasonal dynamics. The results showed that there were 103 kinds of pests of Camellia oleifera under light in Quzhou area, belonging to 6 orders, 33 families and 81 genera. In 2012-2013, 41521 heads of all kinds of Camellia oleifera were seized, mainly on leaf-eating pests; The seasonal variation of population quantity was obviously affected by climatic conditions, the growth period of Camellia oleifera and the picking of tea fruit.
