本题笔者曾于1961—1968年期间在貴溪县万亩山林場进行过平原丘陵地区马尾松毛虫消长规律的研究。从观察马尾松毛虫的种群数量消长,得知马尾松毛虫在江西平原丘陵地区的纯松林内,存在着周期性重复发生的规律。通过对气候、天敌、食料三因子与马尾松毛虫消长规律关系的探讨,认为食料是形成马尾松毛虫周期性重复发生规律的最基本因子,其他均为影响因子。 The author of this article had in the 1961-1968 period in Guixi Wanmu Hill Farm plains hilly areas of Masson pine caterpillar growth and decline of the law. From the observation of population growth and population decline of Dendrolimus punctatus, we know that there is a regular pattern of repeated occurrence of Pinus massoniana in pure Pinus forest in the hilly area of ​​Jiangxi plain. By discussing the relationship between the three factors of climate, natural enemies and foodstuffs and the growth and decline of Masson pine caterpillars, we concluded that the foodstuffs are the most basic factor that causes the periodic recurrence of Dendrolimus punctatus, and the others are the influencing factors.
