中文摘要： 为了科学施药、合理利用和保护自然天敌进行茶丽纹象甲Myllocerinus aurolineatus Voss和茶角胸叶甲Basilepta melanopus Lefevre的综合防治，用灰色系统分析法、生态位分析法和空间格局聚集强度指标分析方法对大别山区茶园2种主要害虫与其捕食性天敌在数量、时间、空间关系等进行分析。综合排序的结果表明：茶丽纹象甲的主要天敌是黑步甲、日本球腹蛛和鞍型花蟹蛛；茶角胸叶甲的主要天敌是草间小黑蛛、锥腹肖蛸和茶色新圆蛛。茶丽纹象甲的λ值小于2，聚集是由环境的影响所致，茶角胸叶甲的λ值大于2，聚集是由昆虫主动聚集或任何一种因素引起的。2种害虫的天敌λ值均小于2，其聚集是由于环境中的某些因子（包括害虫）引起的。
英文摘要： Analysis of the abundance, temporal occurrence and spatial patterns of two Coleopteran insect pests and their predatory natural enemies was conducted using grey system analysis, ecological niche analysis and collective intention analysis. The two insect pests were Myllocerinus aurolineatus Voss and Basilepta melanopus Lefevre. The synthetic ranking results indicate that the dominant natural enemies of M. aurolineatus were Synuchus atricolor Bates, Enoplognatha japonica Boes.et Str. and Xysticus ephippiatus Simon. Dominant natural enemies of B. melanopus were Erigonidium graminicolum Sundevall, Tetragnatha maxillosa Thorell and Neoscona theisi Walckenaer. Average aggregation size of M. aurolineatus was less than two due to environmental factors but the average aggregation size of B. melanopus was greater than two due to the natural tendency of this pest to aggregate.Due to a variety of environmental factors (including pests) the average aggregation sizes of the natural enemies were less than two.
