摘要
１９９２～１９９４年，在浙江省天台县华顶林场北山区铁泉湖黄山松种子园研究了黄山松球果生命表。结果表明，从雌球花开放到球果成熟过程中，导致球果死亡的主要因子是松实小卷蛾幼虫的危害。主要发生期是在雌球花开放，１年生球果生长和２年生球果迅速膨大的５月份。黄山松球果的损失量与黄山松结实的大小年及害虫发生量直接相关。
Life tables of Taiwan pine cones were
establishell and analyzed on Huadingshan Forest Farm, Tiantai,Zhejiang,during 1993～1994.The
results showed that an important and key factor resulting in cone death of Taiwan pine was the
damage by Petrova cristata, which stared from pine pistilliferous flowers blossom to pine maturity,
Tbe period of the cone death was in May each year,There existed a close relationship between the
loss of Taiwan pine cones,the different years of bearing cones and the pest densities.
