毛竹尖胸沫蝉预测预报初步研究

Preliminary Study of Aphrophora notabilis Prediction

提出了毛竹尖胸沫蝉林间虫情调查的最适取样数的确定方法,采用期距法进行该虫发生期中、短期预报;提出查5龄若虫的虫口密度预测来年低龄若虫的虫口基数,为该虫的预测预报提出了科学的方法。

This paper raised the most suitable sample number determination method for the investigation on the conditions of Aphrophora notabilis in the forest;it put forward that the low-instar nympha population base in the next year was predicted by checking the 5th-instar nympha population density,which raised the scientific method for the insect prediction.
