| 摘 要： | 通过组建自然种群生命表来研究暴发年份马尾松毛虫（Dendrolimus punctatus Walker）的种群动态。研究结果表明,在增殖期,马尾松毛虫的存活率达4.27%,种群趋势指数为7.6;在暴发初期马尾松毛虫的存活率为4.25%,种群趋势指数为4.81,增殖期易引起马尾松毛虫种群数量的剧增。这一结果表明,防治马尾松毛虫的关键时期在增殖期末期。

| Abstract: | Researches were conducted on the natural population life table of Dendrolimus punctatus in its outbreak days.The results showed that the survival rate of Dendrolimus punctatus was up to 4.27%,and the population trend index was 7.6 in the proliferation phase.Its survival rate was up to 4.25%,and its population trend index was 4.81 in the early outbreak days.The Dendrolimus punctatus population was easy to sharply increase in the early outbreak days.This result indicated that the key period of controlling Dendrolimus punctatus was in the last stage of the proliferation phase. |
