春尺蠖发生规律及发生期测报初步研究

Preliminary research of occurrence regularity of Apocheima cinerarius erschoff and the forecast of occurrence time

通过野外标准林地及室内饲养调查,总结分析了环境因素,特别是温度对春尺蠖成虫羽化、卵孵化进度及幼虫历期的影响,建立了春尺蠖成虫羽化始盛期直线回归预测式、春尺蠖卵发育历期预测式以及推算各虫态或各虫龄发生期的历期推算法,提出了春尺蠖防治适期的及时准确预测方法,为生产单位及决策部门制订生产计划和防治方案提供了理论依据.

Environmental factors, especially temperature mtluence on emergence, egg hatching and growth stages of Apocheima cinerarius Erschoff were analyzed through field investigation and breeding in lab for several years. The regression forecasting formula of beginning and prosperity of the emergence, hatching stages and speed of the eggs, and growth stages calculating method of Apocheirna cinerarius Erschoff were established. Therefore the periods for prevention of Apocheima cinerarius Erschoff were forecasted, which provided the methods for timely and accurately forecasting the periods for prevention of Apocheima cinerarius Erschoff.
