摘要:
为明确黄板防治和化学防治茶园的节肢动物群落结构差异,采用黄板诱集方法在2015年6—11月进行连续调查取样,研究了2种类型茶园节肢动物群落的结构特征和主要节肢动物发生量。结果表明,黄板防治茶园的假眼小绿叶蝉和粉虱的发生量显著低于化学农药防治茶园,中性昆虫和蚜虫发生量显著高于化学防治茶园,寄生蜂发生量无显著差异。除去蚜虫迁飞这一时期,黄板防治茶园节肢动物群落多样性高于化学防治茶园,2种茶园节肢动物群落的益害比都在7月初出现最大峰值,黄板防治茶园最高达2.095:1,农药防治茶园最高达1.809:1。适时使用黄板防治较化学防治能更好的控制茶园常见同翅目害虫发生量,并较好保持节肢动物群落的群落多样性。茶园使用防治措施应注意7月初和10月份2个特殊时期。

Abstract:
To find the difference in the community structure of arthropods between the tea garden with yellow sticky traps and those using chemical pesticides for pest control, the structure characters of arthropod communities and the occurrence quantity of main arthropods in the tea garden were investigated. Yellow sticky traps were used to collect insect samples from June to November in 2015 in the tea gardens . As results, we found the occurrence quantity of Empoascavitis (gothe) and whitefly in the tea garden with yellow sticky traps was obviously lower than that with chemical pesticides; however, the occurrence quantities of neutral insect and aphid were significantly higher than those with chemical pesticides, and no significant differences were detected in the occurrence quantity of parasitic wasps. The diversity of arthropod communities in the tea garden with yellow sticky traps was significantly higher than that with chemical pesticides except in the period of the aphid’s migration. The ratio of predator prey to arthropod communities in the two tea gardens both appeared the maximum peak in July, which was up to 2.095∶1 with yellow sticky trap and 1.809:1 with chemical pesticides. Using the yellow sticky trap could control the occurrence quantity of common homopteran insects and protect the arthropod community diversity better. In the process of using the preventive measure, the special period of July and October should be considered.
Key words:  tea gardens  yellow sticky trap  chemical pesticide  arthropod community  period
