摘 要:微红梢斑螟是我国主要梢斑螟属害虫之一,怀化地区危害较重。2009年,因该虫大面积暴发,湖南省启动了林业生物灾害II级应急预案。为评估微红梢斑螟在怀化地区的潜在危险性,科学制定防控决策,本文阐述了微红梢斑螟在怀化地区的发生防治情况,并根据我国林业有害生物风险分析准则进行风险性分析和综合评估。结果表明:2009~2020年,微红梢斑螟在怀化地区累计发生268,317 ha,累计防治120,700 ha,该虫在怀化地区的综合评估风险R值为2.45,属于高度危险的林业有害生物。这对今后进一步强化微红梢斑螟监测防治具有一定的指导意义。Dioryctria rubella is one of the main pests of the genus Dioryctria in China, which is seriously damaged in Huaihua. In 2009, because of the large outbreak of the insect pest, Hunan Province launched the II level emergency plan for forest biological disasters. In order to evaluate the potential risk of Dioryctria rubella in Huaihua and make scientific prevention and control decisions, this paper described the occurrence and control of the insect in Huaihua, and carried out risk analysis and comprehensive assessment according to the risk analysis criteria of forest pests in China. The results showed that: from 2009 to 2020, Dioryctria rubella occurred 268,317 ha and controlled 120,700 ha in Huaihua. The comprehensive assessment risk R value of the insect in Huaihua was 2.45, which was a highly dangerous forest pest. This study has a certain guiding significance for further strengthening the monitoring and control of Dioryctria rubella in the future.
