摘要
作者对松大蚜的发生规律进行观察,其易大发生于海拔200~450 m丘陵地区、阳坡、中幼龄林、密度大的马尾松纯林,对其发生原因进行分析,分析表明年平均气温、年平均湿度、年降雨量、年日照时数4种气候因子对松大蚜的发生都起作用,在此基础上提出了防治对策。
Occurrence law of Cinara pinitabulaeformis was observed, it is easy outbreak at the area with altitude of 200-450 m, such as hilly regions, sunny, young and middle fiJrests, pure hrest of Pinus masoniana with high density, the cause was analyzed, the analysis showed that four kinds of climatic factur of annual average temperature, annual average humidity, annual rainfall, annual sunshine time were at work on the oeeun＇enee of C. pinitabulaeformis, on this base, the prevention and control countermeasures were put forward.
