芽梢斑螟危害马尾松雄球花的初步研究

马尾松（Pinus massoniana Lamb.）是我国分布最广、数量最多的松树,是组成亚热带地区大面积森林的主要针叶树种,也是淮河以南酸性土荒山造林的先锋树种。马尾松花粉有良好的医疗和保健价值。汉代《神农本草经》记载松花粉＂气味甘温无毒,主治心腹寒热邪气,利小便,消淤血,久服轻身益气力，延年”。...

The damage of Dioryctria yiai on young shoots of Pinus massoniana and the influence of this pest insect on development of male cone and pollen were studied.It is demonstrated that the wormhole of D.yiai is harmful to the development of male cone,microsporophyll and pollen in the next year.The length and diameter of male cone and microsporophyll number decreased and accounted for 33.3% and 40.2% of the health plant,respectively.The vertical and transverse diameter of microsporophyll accounted for 62.0% and 71.0% of the health plant,and the fresh and dry weight of microsporophyll accounted for 30.3% and 43.6% of the health plant.It is concluded that D.yiai could seriously damage the young shoot of P.massoniana and cause bad development of male cone shoot and pollen abortion.
