楸树无性系对楸蠹野螟抗性的研究及评价

数据采集于山东省菏泽市曹县双刘楼村楸树无性系示范林，旨在筛选抗虫性强的优良无性系，以排粪孔,虫瘿和羽化孔为主要依据,调查13个1年生和11个2年生楸树无性系的楸蠹野螟为害情况,并测量1年生楸树的株高和胸径,计算楸树的被害率,虫口密度,被害指数,相对生长量影响率和活力系数,并以此为指标评价和分析不同楸树无性系对楸蠹野螟的抗虫性及耐虫性，数据质量良好，并已在相关学术期刊发表。Data were collected from a clonal experimental plantation of Catalpa bungei at Shuangliulou Village, Cao County, Heze City, Shandong Province. This study aimed to screen elite clonal varieties with strong insect resistance. Taking frass exit holes, galls and emergence holes as the main evaluation criteria, the damage caused by Omphisa plagialis (Catalpa borer) on 13 one-year-old and 11 two-year-old clonal lines of Catalpa bungei was investigated. Plant height and diameter at breast height (DBH) of the one-year-old trees were measured. Subsequently, the damage rate, insect population density, damage index, relative growth impact rate and vitality coefficient of the trees were calculated. These metrics were employed to evaluate and analyze the insect resistance and tolerance of different Catalpa bungei clones to Omphisa plagialis. The dataset is of high quality and has been published in a relevant academic journal.
