box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">槐尺蠖是一种爆发性强，危害性大（常在短时间内将叶片吃光），繁殖力强（在适宜温度下，5—7天即可孵化出幼虫，且成活率高），防治难度非常大。为了科学有效的防治槐尺蠖，确保防治效果，我们总结出了以下几种防治方法：</span></p><p style="margin-top: 0px;

padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">一、 物理机械防治</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-indent: 2.21428em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">1、挖蛹。重点消灭越冬虫蛹。当年10月至11月初或第二年3月，挖蛹范围重点是树冠垂直投影深度5cm。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-indent: 2.21428em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">2、扑杀幼虫。4月底至9月幼虫发生期，结合幼虫受惊有吐丝下垂的习性，可采用振动树体或喷水等方式，使幼虫吐丝下垂，并集中杀灭。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-indent: 2.21428em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">3、利用黑光灯诱杀成虫。成虫羽化后，白天潜伏在墙壁或灌木丛中，夜晚出来活动，有明显的趋光性。选无风、无月、闷热天气于晚上8-9点时用20-30W的黑光灯，灯距地面1.0-1.5m为宜，灯下5cm处放水盆，盆内放肥皂水，害虫扑灯后落入水中，诱杀成虫。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-indent: 2.21428em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">二、化学防治</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; text-indent: 2.21428em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 18px;">幼虫防治是关键。3龄前使用25%溴氰菊酯乳油、10%的氯氰菊酯乳油1500-2000倍液喷雾防治；化蛹时，可在树下撒15%毒死蜱颗粒剂，每平方米用药3-5g，浅除表土使药剂颗粒进入土层，可杀死化蛹幼虫。</span><span style="margin: 0px;
