宁夏固沙植物柠条种实害虫的初步研究

Preliminary Study of Pod Insect Infesting Sandfixation Plant Caragana Korshinskii in Ningxia

柠条Ｃａｒａｇａｎａｋｏｒｓｈｉｎｓｋｉｋｏｍ．是我国西北荒漠、半荒漠主要固沙造林优良树种。我们于１９９６年在盐池县柳杨堡乡试验采种基地重点对危害柠条种实害虫的柠条豆象ＫｙｔｏｒｒｈｉｎｕｓｉｍｍｘｉｔｕｓＭｏｔｓｃｈｕｌｓｋｙ、柠条荚螟ＥｔｉｅｌａＺｉｎｃｋｅｎｅｌａＴｒｅｉｔｓｃｈｋｅ、柠条种子小蜂ＢｒｕｃｈｏｐｈａｇｕｓｎｅｏｃａｒａｇａｅＬｉａｏ３种害虫进行了调查研究，室内外饲养观测，并对发生规律、危害情况以及生物学习性等进行了初步研究，根据害虫的发生规律确立了适宜的防治适期。

A preliminary investigation and study on three main insect pests infesting caragana korshinskii: Kytorrhinus immxitus Motschulsky,Etiella zinckenella Treitschke and  Bruchophagus neocaragae Liao was made in 1996.By means of indoor feeding and observation in the field, their occurence regularity,life history and biological characters were studied and surveyed systematically.The proper control time and methods were given.
