黄地老虎有多在田间残留的棉茬、谷茬根毛上产卵的习性。自1966年以来,我们通过试验实践,采用根茬诱卵,预测黄地老虎的发生,取得了一定成效。根茬诱卵能较准确地反映大田产卵时期和幼虫发生程度的趋势,并结合黑光灯、杨树枝把诱蛾情况、气象资料进行分析,能较为客观及时地预报黄地老虎发生期、发生程度,并便于制订大田防治措施。方法简便,便于掌握,有利于开展群众运动。多点使用,能因地制宜指导大田防治。
How many yellow tigers in the field remaining cotton stubble, stubble root hair on the habit of spawning. Since 1966, we have experimentally practiced using root stubble to induce eggs and predict the occurrence of yellow tigers. Some achievements have been made. Root stubble can more accurately reflect the oviposition period and larvae in the field trend, combined with black light, poplar branch to the moths, meteorological data analysis, can be more objective and timely prediction of the occurrence of the yellow tiger occurs Extent, and facilitate the formulation of field control measures. The method is simple, easy to grasp, is conducive to the mass movement. Multi-point use, according to local conditions to guide field control.
