鲁西南地区灯诱昆虫种类调查及优势种群动态分析

为了进一步明确鲁西南地区的农业昆虫发生种类及优势种群发生动态,2019年5—9月,笔者在山东省邹城市面坊片区和沈庄片区设置自动虫情测报灯,系统诱集昆虫并鉴定,并对该区域优势种群的发生动态进行分析。诱集结果表明：2019年鲁西南地区灯诱昆虫种类包含6目19科56种,共计53744头昆虫。发生期历时近180天,其中6月中旬—8月下旬为鲁西南地区昆虫的发生盛期,笔者并对危害当地的重要害虫优势种群进行消长动态分析。昆虫优势种群的种类调查和动态分析将有利于及时掌握当地的害虫发生情况,为今后的农业生产提供技术指导。

Insects by Light Trap in Southwest Shandong: Species Investigation and Dominant Population Dynamics

In order to clarify the insect species and the dominant population dynamics in southwest Shandong, the automatic forecast lamps were set up in Mianfang and Shenzhuang of Zoucheng from May to September, 2019. The trapped insects were identified and the population dynamics of dominant insect species were analyzed. The results revealed that there were 53744 insects in total, which belonged to 56 species, 19 families, and 6 orders. The occurrence period was nearly 180 d, the full occurrence was from mid-June to late August, and the population dynamics of dominant species were analyzed. The investigation of insect species and the analysis of dominant population dynamics will benefit the understanding of the occurrence of insect spests in southwest Shandong and provide references for local agricultural production.
