中文摘要:2001~2003年在吉林省柳河县绿色大米生产稻区,采用Logistic模型拟合越冬代二化螟Chilo suppressalis (Walker),有效积温和诱捕器诱蛾百分率的关系。结果表明logistic模型有较好的拟合性。由模型拟合结果预测当地越冬代二化螟发蛾始盛期、高峰期和盛末期所需有效积温
英文摘要:An acceptable logistic forecasting model to monitor the flight pattern of the overwintered rice stem borer, Chilo suppressalis (Walker) in northeastern China, was established during 2001~2003, based on the correlation between the pheromone trap ca
