农作物害虫能否得到有效防治,前提是测报是否准确且及时。害虫测报的重要内容——发生期预报可用田间害虫发育进度作根据。随着系统工程方法的渗透,用于测报的害虫发育进度模型将日益增多。目标害虫各虫态的发育起点温度和有效积温是有关模型的重要参数。我们于1985～1986年进行了室内试验,目的是对玉米螟的上述参数作出估计,为制定田间玉米螟发育进度模型提供 Crop pests can be effectively controlled, the premise is accurate and timely reporting. An important part of pest forecasting - Occurrence forecast can be based on the progress of pest development in the field. With the penetration of systems engineering methods, the pest development progress model for forecasting will increase. The developmental onset temperature and effective accumulated temperature of each insect state of the target pests are important parameters of the relevant model. We conducted an in-house experiment from 1985 to 1986 with the objective of estimating the above parameters for the maize borer, to provide a model for developing the maize borer developmental schedule
