麦蚜虫是小麦上的主要害虫之一，每年发生面积占总面积的９０％以上，造成产量损失８％以上。为了有效地控制麦蚜虫的为害，及时、准确发布麦蚜虫发生预报是开展防治的基础。遥感技术的应用可提高麦蚜测报的手段，提高麦蚜预报的时效性。应用遥感监测农业病虫害是当前世界采用
Wheat aphids are one of the major pests on wheat, with an annual area of more than 90% of the total area, resulting in more than 8% loss of production. In order to effectively control wheat aphid damage, timely and accurate release of wheat aphid is the basis for prevention and control. The application of remote sensing technology can improve the means of wheat aphid reporting and improve the timeliness of wheat aphid prediction. The application of remote sensing to monitor agricultural pests and diseases is the current world adoption
