中文摘要:

为了明确陕西榆林地区农田地下害虫种类组成及优势种群发生动态，于2016年4月1日至2019年9月28日，在陕西省榆林市现代农业示范园，设置太阳能自动虫情测报箱对地下害虫进行收集，在室内对标本进行鉴定和数据分析。在榆林市农田一共灯诱到地下害虫12种，隶属3目5科。地下害虫混合种群发生期为4月中旬至9月上旬，盛发期为4月下旬至8月上旬。小地老虎Agrotis ypsilon、东方绢金龟Maladera orientalis、阔胫绢金龟Maladera verticalis和黄褐丽金龟Anomala exoleta是榆林农田地下害虫主要优势种群。小地老虎灯诱高峰期为4月上旬至5月中旬以及6月上旬至7月下旬，东方绢金龟的灯诱高峰期为4月中旬至6月中旬，阔胫绢金龟灯诱高峰期为6月上旬至8月上旬，黄褐丽金龟灯诱高峰期为6月中旬至7月上旬。本研究为榆林地区农田地下害虫的监测和综合治理提供了基础资料。

英文摘要:

The purpose of this paper is to clarify the species composition and dominant population dynamics of underground pests in Yulin farmland. From April 1, 2016 to September 28, 2019, solar energy automatic pest detection box was set up in Yulin modern agricultural demonstration park of Shaanxi Province to collect underground pests, and samples were identified and analyzed in the laboratory. Results showed that there were 12 species of underground pests in Yulin City, which belonged to 3 orders and 5 families. The occurrence period of mixed population of underground pests was from mid-April to early September, and the peak period was from late April to early August. The dominant populations of underground pests in Yulin farmland were Agrotis ypsilop, Maladera orientalis, M. verticolis and Anomala exoleta. The peak period of light lure for A. ypsilop was from early April to mid-May and from early June to late July, that for M. orientalis was from mid-April to mid-June, that for M. verticolis was from early July to early August, and that A. exoleta was from mid-June to early July. This study provides basic data for monitoring and integrated management of underground pests in Yulin farmland.
