摘    要:利用地统计学中的交叉变差函数法对枣园中枣瘿蚊及其天敌草间小黑蛛种群的空间相关性进行了研究.结果表明,5月21日至10月19日近5个月的枣树主要生育期阶段,除8月27日与9月21日草间小黑蛛与枣瘿蚊种群没有明显的空间相关性以外,其他各次尤其是5月30日与10月19日都充分表现出草间小黑蛛对枣瘿蚊在不同距离下的数量和空间的追随关系,再次证明草间小黑蛛是枣瘿蚊的优势种天敌.

关 键 词:枣园  枣瘿蚊  草间小黑蛛  空间相关性  交叉变差函数

Abstract:Investigations on the spatial correlation of Contarinia sp.and its natural enemy,Erigonidium graminicola,in Feidong county at different periods were conducted with cross-variogram.The results indicated that there is a siganificance spatial dependence between Erigonidium graminicola and Contarinia sp.from 21 May to 19 October except that on 27 August and 21 September.It was showed strongly that the following relationship of Erigonidium graminicola to Contarinia sp.in number and spatial especially on May 30 and October 19.It is demonstrated that Erigonidium graminicola is the dominant natural enemy to Contarinia sp.once again.
Keywords:jujube orchard  Contarinia sp.  Erigonidium graminicola  spatial correlation  cross-variogram
