扶桑绵粉蚧是近年来入侵我国的外来有害生物,本文通过系统调查华南地区城市市区公园、森林公园、植物园、高校校园、园林花卉市场、种植基地、市政、国道、高速公路绿化带以及郊区果园种植基地等生境。结果表明,扶桑绵粉蚧的寄主植物有扶桑、驳骨丹、蟛蜞菊和三裂叶蟛蜞菊,而蟛蜞菊和三裂叶蟛蜞菊在华南地区首次发现是扶桑绵粉蚧的寄主;同时在三裂叶蟛蜞菊上首次发现石蒜绵粉蚧;扶桑绵粉蚧寄生性天敌主要有卡玛长索跳小蜂(Anagyrus kamali Moursi)和Aenasius spPak。并分析了扶桑绵粉蚧危害不同生境园林植物的特点、危害程度,传播扩散的可能成因以及与近缘种的区分。
Fusarium mealybug is an invasive pest infecting our country in recent years. Through systematic investigation of urban parks, forest parks, botanical gardens, college campuses, gardens and flower markets, planting bases, municipalities, national highways and highway green belts in southern China and suburbs Orchard planting base and other habitats.
