为适应微电脑在预测上的应用,本研究设计了以幼虫期龄级组配换算成幼虫发育指数的方法,用以指示松毛虫种群发育动态。使用本研究结果,可以在松毛虫越冬后恢复取食期调查一次发育指数预测全年各虫态的发生期。在二、三代分化初期调查幼虫龄级组配,可以测算二、三代分化比值。 本预测方法已编制成BASIC电算程序并在APPLE-Ⅱ计算机上运行通过。
In order to adapt to the application of microcomputer in prediction, we designed a method to calculate the larval development index of larvae by age-grade group, which is used to indicate the developmental dynamics of Dendrolimus punctatus population. Using the results of this study, it is possible to investigate the occurrence index of developmental stages after the pine caterpillars have recovered from the feeding period to forecast the occurrence stages of all the insect states throughout the year. In the second and third differentiation early investigation of larval age group with, you can calculate the second and third generation differentiation ratio. This prediction method has been compiled into BASIC computer program and runs on APPLE-Ⅱ computer.
