西北地区杀虫植物资源初步调查

Preliminary Investigation on the Resources of Botanical Insecticides in North-western China

我国西北五省(区)部分地区杀虫植物有研究和开发价值的共47种,以分属于豆科的杀虫植物种类最多。这些植物有的是作者亲自观察到和据当地人介绍具有杀虫活性而文献上没有记载过的;有的是文献上已有记载,我们通过调查又加以证实或有新发现的。另外,文中还简要地介绍了这些植物的分布、生境、杀虫特性及应用前景。

The resources of the botanical insecticides were extensively investigated, and plant samples were collected and identified in some areas of the five north-western provinces of China from May, 1989. Forty-seven of them are considered having insecticidal properties.Most of them are leguminous plants,while some species of Celastraceae and Meliaceae possess stronger insecticidal properties. The insecticidal properties of some species of plants were found by our observations or by suggestions of local farmers but not recorded in documents; the others are recorded in documents, and we also verified the properties in our investigation or got some new disco very about their activities to insect pests. The brief narrations are given in this paper about the distributions, habitats, special insecticidal characteristics of these plant species.
