摘要： 性信息素能够准确监测皮暗斑螟成虫发生动态，精确测报其发生量。2年的的监测结果说明，全年蛾主要发生期自4月中旬至8月下旬，有世代交替现象。成虫越冬代羽化相对集中，主要在4月底5月初，其余时间羽化量没有明显的高峰。雄蛾对人工合成性信息素的昼夜反应基本发生在深夜,其反应模式为单峰式——夜间型，敏感时期为午夜0：00-3：00。通过诱捕虫量对虫株率和虫口密度做回归分析，得出性信息素测报皮暗斑螟危害及发生状况，其测报公式为：y诱捕虫量=0.0181x有虫株率；y诱捕虫量=1.0242x虫口密度。

Abstract: the main period of the moth appeared is from the middle ten days of April to the latter part of August.there is not another peak-hour except overwintering generation in the period from the end of August to the beginning of May. The synthetic pheromon can catch the male moth at night，the sole rush hour is 0：00-3：00. The synthetic pheromon can forecast the extent of injury，the formula is y =0.0181x and y =1.0242x.in this formula,y is the amount of the catched males,the first x is the amount of the damaged jujube trees，and the next is the larva density in the forest.
