【摘要】 在设施番茄栽培环境下,采取5点取样法调查黄板诱集的昆虫的种类和数量。利用群落特征指数对昆虫各群落的基本特征进行分析,并应用系统聚类方法对昆虫各群落特征的时间动态进行聚类分析。结果表明,设施番茄诱集昆虫隶属7个目16个科。其中粉虱科Aleyrodidae为优势害虫;在天敌昆虫中蚜小蜂科Aphelinidae为优势种。设施番茄的害虫防治可以分为2段,其中番茄生长初期应充分发挥天敌昆虫的生物防治作用,但是番茄生长中后期,随着害虫数量的剧增,昆虫群落极为不稳定,此时应以化学防治措施为主。更多还原

【Abstract】 In the protected tomato field, the five points sampling method was used to record the species and quantities of insects trapped on yellow templates. The basic characteristics of the insect community were analyzed using basic features of the community characteristics index, and temporal dynamics of the insect community characteristics were clustered using hierarchical clustering methods. The study indicated that the insects were collected by tomato in greenhouse belonged to 16 families, 7 orders. Aleyrodidae was the highest in pests and Aphelinidae was the dominant species in natural enemies. The results showed that the control period of main pests might be divided into two phases. In the early stage of tomato growth, biological control of natural enemies should be given. However, in the middle and later stage of tomato growth, insect community was extremely unstable with the increase of pests, so the chemical control should be adopted.更多还原
