条沙叶蝉[Psammotettix striatus(Lin.1958)]属同翅目、叶蝉科、沙叶蝉属,在欧洲、亚洲的中部、北部及非洲北部均有发生,我国的东北、西北省区亦有发生。多年来,条沙叶蝉在新疆和田地区有不同程度的发生,主要为害冬、春小麦和复播玉米,近几年来危害趋于严重。被害的冬麦苗,叶片受害处形成褐色斑点,受害重者褐色斑点密集成片,全叶枯黄,整个植株矮小瘦弱,分蘖减少。小麦生育后期,条沙叶蝉移至穗部为害。条沙叶蝉还能传播小麦红矮病,1981年和田地区有数百亩冬麦因红矮病严重而被迫翻耕重播。为了弄清条沙叶蝉的发生规律,寻找有效防治措施,我们于1981
Psammotettix striatus (Lin.1958)] belongs to the Homoptera, Cicadellidae, Cicadaceae, in Europe, Asia, central and northern Africa and northern Africa have occurred in China’s northeast and northwest provinces also Have happened. Over the years, the sand leafhopper in the region of Hetian, Xinjiang have varying degrees of occurrence, mainly for the winter, spring wheat and corn replanting, the more serious harm in recent years. Victims of winter wheat seedlings, the leaves affected by the formation of brown spots, the victims of brown spots dense into pieces, full-leaf yellow, the entire plant short and thin, reduce tillering. Late growth stage of wheat, leaf cicadas moved to the ear damage. Leaf-leaf cicadas can also spread red dwarf wheat disease. In winter, a few hundred mu of winter wheat in the Wada area were forced to plow and replay because of severe red-dwarf disease. In order to understand the law of the occurrence of the leaf cicadas, to find effective prevention and control measures, we in 1981
