厦门草圃主要地下害虫的发生与防控药剂引入试验

The occurrence and damage of main underground pests in Xiamen turf nursery and their control pesticides

以厦门灌口草圃为观测试验点,在调查草圃主要地下害虫发生情况的基础上,评判2.5%高效氯氟氰菊酯悬浮剂对蛴螬(Scarabaeoidea sp.)、地老虎(Agrotinae sp.)等主要地下害虫的田间防治效果,提出防控药剂引入试验方法。结果表明,对厦门草圃构成严重威胁的主要地下害虫为蛴螬和地老虎;2.5%高效氯氟氰菊酯悬浮剂对蛴螬、地老虎的田间防治效果尚可,无药害产生,可作为防控药剂予以引入;防控药剂引入试验方法可为亚热带地区草圃主要地下害虫防控药剂田间药效试验准则制定提供参考。

A field survey was conducted to evaluate the field control effect of 2.5% Lambda-cyhalothrin FW on the main underground pests in the turf nursery in Guankou town, Xiameng for proposing a trial meth- ods of introducing prevention and control pesticides. This study showed that the main underground pests were grubs and cutworms in the turf nurseries. The 2.5 % Lambda-cyhalothrin FW effectively controlled grubs and cutworms without phytotoxicity, and could be introduced as a prevention and control pesticide, which would provide useful information for pesticide control in the subtropical turf nursery.
