text-indent: 2em; white-space: normal; box-sizing: border-box;">危害症状：小麦红蜘蛛是小麦生产中的主要害虫，当前是麦蜘蛛活动危害盛期，麦红蜘蛛刺吸麦叶汁液，麦叶受害后先出现白斑，继而发黄，受害轻时麦株矮小，麦穗少儿小，受害严重时不能抽穗，麦株枯干而死。</p><p style="margin: 5px 0px; text-indent: 2em; white-space: normal; box-sizing: border-box;">防治指标：每单行尺虫量达到200头以上时，应及时防治。</p><p style="margin: 5px 0px; text-indent: 2em; white-space: normal; box-sizing: border-box;">防治措施：1.农业防治：抓好田间管理，灌水灭螨 ，麦田灌溉对麦蜘蛛有抑制作用，对于长势较弱麦田，可结合灌水喷施磷酸二氢钾，尿素等使小麦生长健壮，增强抗虫能力。2.药剂防治 可选用哒螨灵、阿维菌素、炔螨特、三唑锡等药剂按照推荐剂量喷雾防治，喷药时水量要大，要打透，使虫体都能着药，效果才会好。</p><p style="margin: 5px 0px;
