摘要
在漯河市农业科学院五里岗试验基地利用吸虫塔诱捕工具,2015-2017连续3年进行了节肢动物群落诱集,并对优势种群蚜虫及其天敌(草蛉、食蚜蝇和瓢虫)进行了系统监测。结果表明,3年来吸虫塔诱集的节肢动物群落的种类和比例保持相对稳定,无大的变动。3年时间共诱捕节肢动物50 251头,分别隶属于7目25科60多种。其中,数量最多的是半翅目的蚜虫,3年共诱集到44 146头,占总虫量的87.85%。吸虫塔下不同年份间蚜虫和天敌的发生数量不尽相同,但发生动态和峰期基本保持一致。蚜虫每年有一大一小两个发生高峰,高峰期在4月中、下旬至5月下旬和9月,高峰期内的虫口数量占总蚜虫量的86%以上。天敌昆虫的发生具有跟随现象,其发生高峰相对滞后10~20 d。
Arthropod population, especially aphid and its natural enemies（lacewing, hoverfly and ladybug） were investigated with a suction tower from 2015 to 2017, in the Wuligang experiment field of Luohe Academy of Agricultural Sciences. The results showed that the species and their compositions kept relatively stable in recent three years. In total,50251 individuals of arthropods comprised of more than 60 species belonging to 25 families in 7 orders were collected under suction trap, in which 87.85% were aphids. The occurrence dynamics of aphids and their natural enemies maintained basically consistent among three years. Two different peaks of abundance of aphids occurred in mid-and-late April to late May and September every year. The two peaks accounted for more than 86% of individuals of aphids. The peaks of natural enemies were 10-20 days late following the peaks of aphids.
