摘要: 本文根据田间调查资料,应用8种聚集度指标分析了苹果苜蓿苔螨在苹果园内的种群空间分布情况。结果表明:苜蓿苔螨的成、苔螨及卵的空间分布均属聚集分布;分布的基本成分为个体群。树冠不同方位的各虫态分析,平均密度及平均拥挤度均以中部高于其它方位,而聚块性指标则以中部最小;其聚集强度表现为卵 > 若螨 > 成螨的规律。

Abstract: Eight aggregation indices were used to analyse the investigated spatial distribution of Apple vlover mite (Bryobia praetiosa Koch) in the orchards.Results showed: 1) The adults,nymphs and eggs distributed as an aggregating pattern and the fundamental component part was the group of individuals.2) Im various directions exist various morphologies too.Horizontal … analy … sising the aggregation from various directions,the average density and crowd were highest in the central part,but the aggregation index was smallest in this part.Vertical analysis showed the rule:eggs,nymphs,adults.

Key words: APPLE, BRYOBIA PRAETIOSA KOCH, SPATIAL PATERN, AGGREGATION INDICA, POPULATION, PEST-INSECT SURVEY
