| 中文摘要: |
| 为明确吉林省公主岭甲虫种类及发生动态, 提供甲虫群落多样性资料，本研究于2021年－2023年利用高空探照灯、虫情测报灯逐日诱集甲虫并分类, 初步探明了各甲虫的种群动态, 并依此分析了甲虫群落的多样性。结果共采集、鉴定甲虫16科58种, 优势科是步甲科(37.93%), 其次为鳃金龟科(12.07%); 明确了甲虫的发生期、发生量及食性, 区分确认天敌昆虫34种, 中性昆虫8种, 害虫20种。主粮作物害虫包括玉米害虫12种, 大豆害虫8种, 水稻害虫1种; 其中, 7月的甲虫群落丰富度最高, 7月、9月的甲虫群落多样性较高, 不同时期群落均匀性无显著差异, 6月－8月间群落相似性较高。确定了不同月份的甲虫优势种及其优势度指数。研究结果可为该区域甲虫的预测预报及有效治理提供基础理论依据。 |
| 英文摘要: |
| To determine the species composition and population dynamics of beetles in Gongzhuling, Jilin province, and to provide a reference for understanding their community diversity, beetles were collected daily from 2021 to 2023 using vertical searchlights and pest monitoring light traps. A total of 58 species from 16 families were identified, with Carabidae (37.93%) being the dominant family, followed by Melolonthidae (12.07%). The occurrence period, abundance, and feeding habits of beetles were investigated. Thirty-four species were identified as natural enemies, eight as neutral insects, and 20 as crop pests, including 12 corn pests, eight soybean pests and one rice pest. Species richness peaked in July, while community diversity was highest in September and July. No significant differences were found in community evenness across months, but community similarity was higher between June and August. Dominant species and their dominance indices were identified for each month. These results provide a theoretical basis for the monitoring and integrated management of beetle populations in the region. |
