摘要
以枸杞木虱危害的枸杞园内"宁杞1号"枸杞为试材,研究了枸杞木虱种群的数量动态及其在枸杞树冠上的垂直分布特征。结果表明:6月是枸杞木虱数量最多的月份;枸杞木虱在枸杞树冠各层的分布数量由大到小的顺序是中上层、中层、中下层、下层和上层;枸杞木虱在中层和中上层活动性最强,与其它各处理间差异显著,田间实施对枸杞木虱的种群控制时,应以枸杞中层和中上层为重点喷雾区域。
Taking ‘ Ningqi No. 1＇ as material, the quantitative dynamic and the vertical activity habits of population of Paratrioza sinica Yang ＆Li were studied. The results showed that amount of Paratrioza sinica Yang ＆ Li was the most in June. The vertical activity habits of each treatment from the strong to weak order was the middle-upper layer, the middle layer,the middle-lower layer,the lower layer and the upper layer. The middle-upper layer and the middle layer in which the vertical height had the strongest activities habits had significant difference with other treatments. It showed that the middle-upper layer and the middle layer were the most important spray areas when control its population in field.
