| 摘 要： | 系统调查研究表明,在实验室条件下松突圆蚧的死亡率随着降雨量的增加而升高,但降雨对不同虫龄的校正死亡率影响不大;不同树种和不同郁闭度林分的虫口数量存在显著差异,其中黑松的虫口数量最高,马尾松次之,湿地松最低,郁闭度高的林分虫口密度大;上半年阳坡虫口高峰出现时间比阴坡早,下半年阴坡虫口高峰出现时间比阳坡早;迎风坡的虫口密度...

| Abstract: | In laboratory conditions,mortality of the pest population increased with rainfall,and the corrective mortality was no significant differences among different development stages.Contrastive experiments indicated that the population quantity of the pine armored scale(Hemiberlesia pitysophila Takagi) showed significant differences between the host pine of masson pine,Japanese black pine and slash pine,in which the population quantity was the highest on Japanese black pine followed by masson pine,and slash pine... |
