城市入侵害虫悬铃木方翅网蝽在四川的危害及风险评估

The Harm and Risk Assessment of the Urban Invasive Pest Corythucha ciliata in Sichuan Province

摘要: 悬铃木方翅网蝽（Corythucha ciliata）是一种林业危险性入侵害虫，主要危害悬铃木属植物。近年来，悬铃木方翅网蝽在四川地区悬铃木属植物上的危害状况呈逐年上升趋势。为了有效防治该害虫，作者于2018年6月至2019年5月对四川境内成都市、南充市、广安市、泸州市、宜宾市等各地的悬铃木方翅网蝽发生情况进行了调查，通过有害生物危险性分析方法，对悬铃木方翅网蝽的风险分析进行定性和定量分析，结果得出悬铃木方翅网蝽的风险值R=1.60，表明悬铃木方翅网蝽在四川省属于中度危险的林业有害生物。

Abstract: Corythucha ciliata is a dangerous invasive pest in forestry, mainly infesting Plantanus spp.. In recent years, the infestion of C. ciliata has become more serious on Platanus spp. trees in Sichuan. In order to prevent the pest effectively, an investigation was conducted to find out the occurrence regularity of C. ciliata in Chengdu, Nanchong, Guang'an, Luzhou and Yibin from June 2018 to May 2019. Through the method of pest risk analysis, the qualitative and quantitative analysis was made of the risk of C. ciliata. The results showed that the risk value (R)of C. ciliata was 1.60, indicating that C. ciliata belonged to moderately dangerous forest pest in Sichuan.
