柠条具有防风、固沙、保持水土的优良特性,在“三北”防护林体系建设中是一个重要的灌木树种。目前,在我县是主要的栽培灌木。近几年来,由于柠条种实害虫的为害,致使种子产量、质量显著降低。一般为害荚果达14.5～46.3%,为害种子达22.5～28.5%,成为柠条种子经营上一个急待解决的问题。为此,我场从1966～1978年,先后对为害柠条种子的害虫种类、生活史、习性以及防治方法进行了试验研究。现将所得资料整理如后。一、柠条种实害虫的种类调查根据我场几年的调查研究,现已发现为害柠条种子的害虫主要有5种: Caragana has the excellent features of windbreak, sand fixation and water and soil conservation. It is an important shrub species in the construction of the “Three North” shelterbelt system. At present, in my county is the main cultivation shrubs. In recent years, due to the damage caused by the pests of Caragana korshinskii, resulting in significantly reduced seed yield and quality. Generally harmful pod up to 14.5 ~ 46.3%, the damage of seeds up to 22.5 ~ 28.5%, Caragana seed become an urgent problem to be solved. To this end, my field from 1966 to 1978, successively on the pest species, life history, habits and methods of prevention and treatment of Caragana korshinskii were studied. The information is now sorted as follows. First, the species of pest species Caragana Investigation According to my field of investigation and study for several years, it has been found that the pests of kelp seed damage has five main types:
