中文摘要:

为明确河南省新乡地区农田地下害虫优势种群组成、发生动态及影响因子，本研究于2015-2021年间利用虫情测报灯对该地区的金龟甲进行了监测。结果表明铜绿丽金龟Anomala corpulenta Motschulsky和暗黑鳃金龟Holotrichia parallela Motschulsky为河南新乡小麦-玉米/花生1年2熟制农田地下害虫的优势种群，且暗黑鳃金龟的年度诱虫量及其在混合种群中的占比呈逐年增加趋势。金龟甲的发生在不同年份呈现单峰或双峰，暗黑鳃金龟发生盛期表现出明显的隔日出土现象即双倍节律。相较于暗黑鳃金龟发生期的6月中旬至9月上旬，铜绿丽金龟的发生期相对较短，在6月下旬至8月下旬。同时暗黑鳃金龟高峰日也晚于铜绿丽金龟，其中高峰日最多差22 d。金龟甲的发生与环境降雨、湿度、温度相关。本研究为新乡地区乃至黄淮海农田地下害虫的危害预警和综合治理提供数据支撑。

英文摘要:

To clarify the species composition, annual dynamics and influencing factors of dominant population of underground pests in Xinxiang, we sampled beetles using pest monitoring lamps from 2015 to 2021. The results showed that Anomala corpulenta and Holotrichia parallela were the dominant populations in the wheat-corn (or peanut) double cropping system. The annual trapping number and proportion of H. parallela in the mixed population showed an increasing trend during 2015-2021. The occurrence of beetles showed single or double peaks in different years, and H. parallela appeared on the ground every two days, known as the circabidian rhythm. The peak period of light lure for H. parallela was from mid-June to early September and that for A. corpulenta was from late June to late August. Meanwhile, date of peak occurrence of H. parallela was later than that of A. corpulenta, with a 22-day maximum difference. The population dynamics of beetles are related to rainfall, humidity and temperature. This study provides a scientific basis for the early warning and integrated pest management of underground pests not only in the Xinxiang area, but also in the Huang-Huai-Hai Region.
