两年两地的试验结果表明 ,二化螟性诱剂可代替测报灯直接用于二化螟发生期预测。以蛾量突增日性诱剂预测的结果比测报灯诱测结果更接近实际发生情况 ,同时避免了测报灯受灯光干扰和电压不足的影响。可设置2～ 4盆性诱剂 ,4盆的诱测结果与实际发生的吻合程度最高 ,其次是 3盆。进入盛发期后 ,性诱剂诱蛾数量多 ,可适当合并突增日 ,作为峰期时段考虑 ,指导大田防治
The test results in two years show that the use of sex-attractant of the rice stem borer (Chilo suppressalis) may replace the report light and be used directly for the prediction of the occurrence of Chilo suppressalis. The results of moths sudden increase of lure attractant were closer to the actual situation than the report light test results, and at the same time avoid the influence of light interference and voltage shortage of report light. 2 ~ 4 can be set to potted lure, 4 pots of the test results and the actual occurrence of the highest degree, followed by 3 pots. Into the Shengfa period, the number of sex attractant moths may be appropriate merger sudden day, as the peak period to consider, to guide field control
