| 摘 要： | 采用4种频次比较法和6种聚集指标公式测定了甘薯卷叶蛾幼虫空间分布型。结果表明，其在甘薯生长期间的分布是聚集分布。其聚集分布的原因是由环境条件所造成的。确定了理论抽样数据和田间抽样技术。 |
| 关 键 词： | 甘薯 卷叶蛾 幼虫 空间分布型 应用 聚集分布 环境条件 抽样数据 |

| Abstract: | The distribution pattern of the larva of Brachmia macroscopa was determinated by using 4 methods of freguency distribution and 4 methods of distribution pattern index.The results showed that their distribution patterns all belonged to the eggregated pattern during the growth stage of potato and this pattern was caused by environment factors.The numbers of Theoretical sumpling and the sumpling method in field were determinted. |
| Keywords: | the larva of Brachmia macroscopa distribution patten number of theoretical sumpling sequential sampling largest sumpling number |
