分析了葛藤节肢动物种类组成以及主要植食性昆虫种类豆突眼长蝽Chauliops fallax、筛豆龟蝽Megacopta crabraria记、龟蝽类Megacopta spp．和Aponsila spp．、叶甲类和叶蝉类的种群数量动态,调查共获得节肢动物15目87科212种,其中植食性节肢动物43科138种,非植食性节肢动物44科74种．主要植食性节肢动物种类的种群水平表现出上半年高于下半年的特点,叶蝉类和豆突眼长蝽的数量水平在5个种类中相对较高,是葛藤天敌调查研究的重点种类．

Composition of arthropods and population dynamics of main insect groups on Pueraria lobata

Composition of arthropod species on Kudzu, Pueraria lobata and the population dynamics of five main phytophagous insect groups were analyzed. It showed that 212 species of arthropods on Pueraria lobata, from 87 families belonging to 15 orders were collected and identified, and 138 species of them, which are from 43 families, feeding on Pueraria lobata. There were a regulatory population dynamics of five phytophagous insect groups, small bean bug Chauliops fallax, sieve pore bug Megacopta cribraria, Megacopta spp., leafbeetles and planthoppers. Three peaks of population dynamic of C. fallax were found in the year. The first peak occurred in middle and late April, the second one occurred in late June to early July and the third one occurred in early and middle September while the low level of population in middle and late November to next February was observed. Three peaks of population of M. crabraria were found in middle May, late June and September, respectively. Two peaks of leafbeetles population and four peaks of Megacopta spp. and planthoppers population were observed. On the other hand, the results of analysis on populations showed that the level of population in the first half year was higher than that in the second half year, and that Chauliops fallax and planthoppers were more important than others species.
