摘要

为评估大豆豆荚螟虫(leuminivora glycinivorella(Matsumura))的危害风险和选择防治方法,2015 - 2018年在新潟县和长野县对200多块大豆田进行了调查,并对这些大豆田施用了0-2次杀虫剂。对未处理的数据进行决策树分析。该树模型有4个终端节点,并按大豆连作年、前一年的损失率和与最近的前一年大豆种植地的距离3个因素进行分割。根据每个节点所分类的场的损伤程度,将4个终端节点从低到高排序。建模数据和测试数据之间的节点顺序没有区别,测试数据来自其他不受控制的字段。随着杀虫剂处理次数的增加,除最高害级节点外,其余末端节点低害级田的比例均增加到90%以上。这些结果表明,四个终端节点的顺序可以代表损伤风险的顺序。该树模型可为合理选择杀虫剂处理次数或种植前大豆轮作水稻提供理论依据。

Pre-planting Estimation of Damage Risk and Selection of Control Methods for the Soybean Pod Borer, Leguminivora glycinivorella(Lepidoptera: Tortricidae)
To estimate the damage risk and select control methods for the soybean pod borer, Leguminivora glycinivorella(Matsumura)(Lepidoptera: Tortricidae), over 200 soybean fields cultivated by farmers and treated with insecticides 0–2 times for the borer were surveyed in Niigata and Nagano Prefectures from 2015 to 2018. A decision tree analysis was performed on the non-treated data. The tree-model had four terminal nodes and was split by three factors: soybean continuous cropping year, damage rate in the previous year, and distance to the nearest field where soybeans were cropped in the previous year. The four terminal nodes were ordered from low to high according to the damage level of the fields classified to each node. The order of nodes did not differ between the modeling data and test data, which were data from other uncontrolled fields. As the number of insecticide treatments increased, the ratio of low-damage-level fields increased to > 90% in all terminal nodes except the highest-damage-level node. These results indicate that the order of the four terminal nodes may represent the order of damage risk. The tree-model may enable rational selection of the number of insecticide treatments or rotation of soybean to rice before planting.
