中文摘要：

稻水象甲[Lissorhoptrus oryzophilus（Kuschel）]是我国植物检疫对象。采用Taylor幂法则及Iwao回归分析法对江西省双季稻区早稻田稻水象甲越冬代成虫及晚稻田禾苗上取食斑的分布型进行测定,结果表明双季稻区早稻田间成虫主要呈聚集分布,晚稻田间禾苗上新一代成虫的取食斑也呈聚集分布。

英文摘要：

The rice water weevil,Lissorhoptrus oryzophilus（Kuschel）,is nationwide object of rice quarantine.Its spatial distribution pattern of hibernative adults in early rice fields and feeding scars in late rice fields were analyzed with Taylor’s power law and Iwao’s distribution function in double-rice regions in Jiangxi Province.The results indicated that the spatial distribution pattern of both the hibernative adults and feeding scars presented aggregation distribution.
