Abstract In order to comprehensively grasp the occurrence and damage situation of forest pests in Ding'an County and meet the needs of the scientific control of the forest pests and the construction of ecological civilization, a survey of forest pests were conducted in the natural forests, plantations, flowers, seedlings, seeds, fruits, wood and their products in Ding'an, Hainan from December in 2016 to October 2017. The results showed that there were 46 species of forest pests, of which there were 21 species of pest insects with an area of 1318.20 ha, 23 diseases with an area of 1733.20 ha, and 2 harmful plants with an area of 86.67 ha. The current situation and occurrence of forest pests in Ding'an were analyzed, based on which some suggestions were put forward, such as strengthening of the plant quarantine work, enhancing of the monitoring ability and strengthening of the forest pest control team.

我国林业有害生物危害已成为一种自然灾害,其发生具有潜伏性、传播性和周期性等特点,在生态建设和林业产业发展过程中,对地区生态安全构成巨大威胁,对地区经济发展造成巨大损失,被称为“不冒烟的森林火灾”[1-2]。海南省位于中国最南端,森林面积为2.14万km2,森林覆盖率62.1%,截至2015年,海南省主要林业有害生物发生呈平稳态势。林业有害生物发生面积2.57万hm2,其中,病害发生626.67 hm2,虫害发生1.02万hm2,有害植物发生1.48万hm2。椰心叶甲、桉树枝瘿姬小蜂、薇甘菊、金钟藤等重大林业有害生物对海南省森林资源已构成严重威胁[3-4]。
林业有害生物普查,旨在查清当地林业有害生物的种类、分布范围、传播情况、发生面积及危害情况,建立和完善当地林业有害生物数据库,为今后有效防控林业有害生物提供理論依据。根据国……
