摘  要：
通过标准地调查研究了微红梢斑螟蛀害对马尾松幼林生长的影响,并对剪梢防治微红梢斑螟的方法进行了简述。结果表明:微红梢斑螟蛀害对马尾松幼林生长产生了显著影响,受害后主梢当年生长量损失27.23%,树高下降13%,而地径增长7.23%。马尾松受害后除影响当年梢生长外还影响其次年梢生长。树高在141～180 cm左右的马尾松受害后对抽梢的影响最大。因此,防治重点应在141～180 cm树高范围的松树,即3～4年生松树。综合微红梢斑螟在湖南的发生特点,湖南省剪梢防治微红梢斑螟宜在5月中上旬进行。

摘  要：
Based on the data from investigation on sample plots of young Pinus massoniana forest,the effect of damage caused by Dioryctria rubella on the growth of young P.massoniana forest was estimated,meanwhile the shoot cutting technique was briefly introduced.The results showed that,the damage of D.rubella had a significant effect on the growth of young P.massoniana plantation.After suffering the damage of D.rubella,the current growth of leading shoot was reduced by 27.23%,and the tree height growth decreased by 13%,while the ground diameter growth increased by 7.23%.The damage of D.rubella not only influenced the shoot growth in the first year,but also influenced the shoot growth in the next year.After suffering the damage,the shoot growth was deeply influenced with tree height of 141~180cm.Hence,the aim of control should focus on the pine with the height from 141 cm to 180 cm,namely,the pine in the age between 3 to 4 years old.Comprehensive analysis of the occurrence characteristics of D.rubella in Hunan showed that,the shoot cutting to control D.rubella should be carried out in the early-middle May in Hunan province.
