赣州新发现入侵物种菊方翅网蝽

Corythucha marmorata——An Invasive Pest Newly Recorded at Ganzhou City, China

2016年在赣州新发现了外来入侵物种——菊方翅网蝽[Corythucha marmorata(Uhler,1878)],首次发现菊科蔬菜紫背天葵[Gynura bicolor DC.]是其寄主。菊方翅网蝽在赣州野生的紫背天葵、菊芋、苍耳、向日葵、小蓬草、女菀、鬼针草和加拿大一枝黄花上易见,并对菊芋、苍耳造成较严重危害,9—10月受害严重的叶片平均有成虫、若虫25~30头,叶片提前干枯。推测菊方翅网蝽是随菊科花卉从广州周围流入,侵入赣州时间有8~10年。鉴于菊方翅网蝽会对菊芋造成较严重危害,建议有关省和部门立即开展菊方翅网蝽的风险分析评估。
