经观察马尾松种子园种实害虫和害鼠的种类有21种,严重危害的有松瘿蚊、马尾松窃蠹、芽梢斑螟、松实小卷蛾、油松球果小卷蛾、微红梢斑螟和社鼠。根据马尾松生殖发育规律,观测了主要种实害虫、害鼠的危害顺序及其程度。研究了主要种实害虫在树冠上的种群分布及其演变规律。结果表明,主要种实害虫的幼虫种群数量比率与寄主树上的雄花枝、2年生球果数量比率相吻合。根据马尾松种子园的生态特点,提出了主要种实害虫、害鼠的综合治理措施:(1)清理园内外林地残梢断干;(2)秋后采果除虫;(3)筛选园中抗虫无性系,结合疏伐去劣留优;(4)在主要种实害虫蛰居枯果、枯梢的越冬期和卵及初孵幼虫期,进行化学防治
The results showed that there were 21 species of pest and pest in the masson pine seed orchard, and the species of Pinus massoniana, Pinus massoniana, Budding moth, Pinus tabulaeformis, Pinus tabulaeformis, Red-spotted borer and community rats. According to the rule of reproductive development of Pinus massoniana, the order and degree of damage of main pests and harmful rats were observed. The population distribution and evolution of main species of pests on canopy were studied. The results showed that the population ratio of larvae of the main species of pests was consistent with the ratio of the population of male flowers and 2-year-old cones in the host tree. According to the ecological characteristics of Pinus massoniana seed orchard, put forward the main kinds of pests, harmful rats integrated control measures: (1) to clean up the woodland debris off the trunk dry; (2) post-harvest fruit pest; (3) Screening Park (4) chemical control of the main species of pests live in dead fruits, dead ends and eggs and newly hatched larvae during chemical control
