摘要
本文论述了雅氏山蝉 (Leptopsalta yamashitai (Esaki and Ishihara) ,comb.nov.)的形态特征 ,采用了标准地逐株调查法调查了防治前、后雅氏山蝉成虫在花椒上的分布 ,用频次比较法拟合其空间分布型 ,初步得出该蝉在花椒林呈 Possion分布 ,并提出了相应的防治对策。
The morphological chacracteristics of Leptopsalta yamashitai (Esaki and Ishihara),comb.nov. were described. Based on the method of standard spot investigation, the distribution pattern of the insect was analysised in different times of prevention.It was shown that the distribution pattern of the insect is Possion, and the prevention methods were put forword.
