摘要
采用定点、网捕、挖土取样等调查方法,对乌拉尔甘草(Glycyrrhiza uralensisFisch)主产区的沙地、梁地、滩地等生境进行了系统调查。首次记录了甘草害虫116种,天敌81种,隶属昆虫纲12目,77科;蛛形纲2目,3科。揭示了各生境的种群组成及其比例。为甘草主产区不同生境的害虫防治提供了依据。
The methods of fixing points, net trapping and soil samplings are used to survey the pests and natural enemies of Clycrrhiza uralensis Fisch in such living habitats as in sands, Liang lands and bank lands systematically. 116 species of the pests and their 87 species of natural enemies are recorded. They belong to 77 families, 12 orders of insects; and 3 families,2 orders of Arachida. The results indicated the components of main species of pests and natural enemies in different habitats and the ratio of their populations, thus providing the scientific bases for the prevention and control of the insect pests in different habitats.
