麦二叉蚜是我师塔里木垦区小麦、高梁的重要害虫,一般年份可使小麦减产一成,严重时达三成;高梁受害更重,不加防治,则难有收成。从一九六二年以来,我们坚持“实践第一”的观点,对麦二叉蚜的发生规律和防治进行了反复的调查和研究,获得了一定成效。 一、麦二叉蚜的生物学特性和发生规律 麦二叉蚜在本区完全以卵越冬。越冬卵多发见于冬麦田的枯枝落叶内和田边的草丛 Wheat aphid is my division Tarim reclamation wheat, sorghum an important pest, the general year wheat yield can be reduced 10%, severe up to 30%; sorghum victims more weight, without control, it is difficult to harvest. Since 1962, we have adhered to the concept of “practicing first” and have conducted repeated investigations and studies on the occurrence and prevention of wheat aphides and achieved some success. First, the biological characteristics of wheat aphids and the occurrence of the law Wheat aphids completely winters in the area of ​​eggs. Wintering eggs found in the litter of winter wheat fields and grassland edge and more
