摘要
为茶棍蓟马的预测预报及制定科学有效的防控措施提供理论依据,通过实地调查,采用I指标、C A指标、L指标、扩散系数C和K指标等5种聚集度指标,结合Taylor的幂法则和Iwao的M*-x-直线回归方法研究贵州中部地区茶园茶棍蓟马的空间分布格局。结果表明:在贵州中部地区茶园中茶棍蓟马成虫及若虫的空间分布均呈聚集分布,但成虫表现为个体间相互排斥(Iwao回归方程M*成虫=-0.4190+1.5593 x-,α<0),若虫表现为个体间相互吸引(Iwao回归方程M*若虫=5.2675+1.3974x-,α>0)。
The spatial distribution pattern of Dendrothrips minowai in tea garden was studied by using 5 aggregation indexes(I,C A,L,C and K),Taylor power law and M*-x-linear regression method through field survey to provide the theoretical basis for prediction and forecast of D.minowai and formulation of scientific effective prevention and control measures in Central Guizhou.Result:The spatial distribution of D.minowai adults and nymphs in tea garden shows an aggregation distribution pattern but there is a mutual exclusion phenomenon(M*adults=-0.4190+1.5593 x-,α<0)between individuals of D.minowai adults and a mutual attraction phenomenon(M*nymphs=5.2675+1.3974 x-,α>0)between individuals of D.minowai nymphs.
