摘要
朱红毛斑蛾是一种重要的榕树食叶害虫。通过对深圳、惠州、东莞、广州4个城市的街道进行随机抽样,实地调查朱红毛斑蛾于2017年在4个城市爆发程度。在调查结果中以受害榕树的叶片损失率作为指标衡量受害程度。发现在4个城市中,榕树受害程度最严重的两个城市为深圳和东莞,广州和惠州的受害程度相对较低。受害的榕树品种为垂叶榕和小叶榕。其中垂叶榕的受害程度在调查地区普遍高于小叶榕。分析结果表明朱红毛斑蛾的爆发具有偶然性,同一时间段不同地区的爆发程度不同。
In August and September of 2017, An investigation of streets of 4 cities （Shenzhen, Huizhou, Dongguan,Guangzhou） was conducted to figure out in what degree 2 species（Ficusconcinna and Ficus benjamina）widelyplanted along streets in Cantonwere gnawed by larvae of Phauda flammans （Lepidoptera） -a pest feeding specifical-ly on certain species of genus Ficus. In each city several streets along which Ficus concinna and Ficus benjaminahad been planted were randomly selected and investigated. The result shows that the degree of leaf devastation ismost severe in the Shenzhen and Dongguan while the 2 species in Guangzhou and Huizhou suffer less from leafdevastation. The result also suggest that Ficus concinnasuffer less from pest devastation than Ficus benjamina.
