石斛园昆虫群落特征分析

摘  要
系统调查了石斛园昆虫群落组成及结构,应用群落特征参数分析方法分析了石斛园昆虫群落组成和结构的变化、群落特征及时间格局对昆虫群落结构及多样性的影响进行了调查研究。结果表明,石斛园昆虫群落63种,分属于11目39科。石斛园昆虫群落结构在时间序列上保持稳定,但在个别时间上表现差异和波动。发生量较大、持续时间较长的主要有棉蚜(Aphis Gossypii Glover)、小绿叶蝉(Empoasca flavescens (F.))、水稻芋蝗(Gesonula punctifrons (Stdl))等。研究结果为石斛害虫综合治理和生态调控措施的制定及实施提供了理论依据。

Analysis on insect community character in gardens of Dendrobium
 

Abstract
Systematic investigation insect community composition and structure in garden of Dendrobium, the application of community characteristics analysis parameter analysis of Dendrobium Park community composition and structure of insects to changes in community characteristics and the time pattern of the insect community structure and diversity research. The results show that the Dendrobium Community Park, 63 kinds of insects, belonging to 11 orders 39 Division. Dendrobium garden insect community structure in the time series to remain stable, but in time the performance of individual differences and fluctuations. Occurrence of larger, longer duration of the main cotton aphid (Aphis Gossypii Glover), leafhopper (Empoasca flavescens (F.)), Rice lines locust (Gesonula punctifrons (Stdl)) and so on. The results for the Dendrobium and ecological pest management control measures designed and implemented to provide a theoretical basis.
