摘  要:
应用性信息素对河北地区枣树皮暗斑螟进行了林间监测。结果表明,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。

摘  要:
Dynamics is Monitoringd on Euzophera batangensis Caradja by using the Sex-pheromon from 2006t o 2009 in Hebei of China.the main period of the moth appeared is from the middle ten days of April to thel atter part of August.There is not another peak-hour except overwintering generation in the period from thee nd of August to the beginning of May.The synthetic pheromon can catch the male moth at night,the sole rushh our is 0:00-3:00.The synthetic pheromon can forecast the extent of injury,the formula is y=0.0181x andy =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.
