摘 要: 质优量足的草莓苗是大棚草莓生产的基础,但目前对其苗圃害虫的组成和动态了解贫乏。本研究采用黄色粘虫板在草莓的苗圃系统调查主要节肢动物组成和季节性动态变化,发现在苗圃早、中期的7月和后期的9月初,节肢动物多样性指数、物种数和总个体数相对较高,其中植食者占有很高的比例。烟粉虱、蓟马和蚜虫是草莓苗圃节肢动物群落的优势种群。 Sufficient and well-qualified strawberry seedlings are the prerequisites for strawberry production in large scale in plastic greenhouse and in field. To fill the knowledge gap in pest management in strawberry nursery, sticky yellow board was used to investigate the composition and seasonal dynamics of biodiversity of arthropod community. The results showed that the biodiversity indices, the numbers of species and individuals were peaked twice, respectively during the early middle stage of nursery in July and during the beginning of September. Most of the arthropods sampled were herbivores. The whitefly Bemisia tabaci (Gennadius), the western flower thrip Frankliniella occidentalis Pergande and the green peach aphid Myzus persicae(Sulzer) were the dominant species in the community.
