The twolined spittlebug, Prosapia bicincta (Say) (Hemiptera: Cercopidae), is a major economic pest of turfgrass, forage grass, and sugarcane. Native to the southeast United States, it impacts rangelands and the landscape trade by damaging pastures, golf courses, urban landscapes, and lawns. This insect pest was reported and confirmed in Hawaiʻi for the first time in 2016, the first species in the family Cercopidae to invade Hawaiʻi. On Hawaiʻi Island, P. bicincta is severely devastating Hawaiʻi’s beef cattle industry. Since its initial detection, P. bicincta has rapidly expanded its range across an estimated 72,183 ha area on Hawaiʻi Island, and it continues to disperse to new locations. In areas of high infestation, this pest has caused 100% dieback of key pasture grasses for livestock forage, including kikuyu (Pennisetum clandestinum Hochst. Ex Chiov) and pangola (Digitaria eriantha Steud) grasses, leading to the establishment of low-quality forage grasses and weeds. Additionally, this pest may affect the Hawaiʻi landscape trade and impact golf courses, urban landscapes, and homeowners. The taxonomy, detection history, range, biology, ecology, economic damage, and management strategies for P. bicincta are discussed.

双线飞蛾（半翅目：鹿科）入侵夏威夷：一种破坏性饲料草害虫的定居、生物学和管理

双线飞虱 Prosapia bicincta (Say)（半翅目：鹿科）是草坪草、饲料草和甘蔗的主要经济害虫。它原产于美国东南部，通过破坏牧场、高尔夫球场、城市景观和草坪来影响牧场和景观贸易。2016 年，夏威夷首次报告并证实了这种害虫，这是鹿科中第一个入侵夏威夷的物种。在夏威夷岛上，P. bicincta 正在严重破坏夏威夷的肉牛业。自首次发现以来，P. bicincta 已迅速扩大其活动范围，覆盖夏威夷岛约 72,183 公顷的面积，并继续扩散到新的地点。在高侵染地区，这种害虫已导致牲畜饲料的主要牧草 100% 枯死，包括基库尤草 (Pennisetum clandestinum Hochst. Ex Chiov) 和马唐草 (Digitaria eriantha Steud)，导致低品质饲草的建立和杂草。此外，这种害虫可能会影响夏威夷景观贸易，并影响高尔夫球场、城市景观和房主。讨论了 P. bicincta 的分类、检测历史、范围、生物学、生态学、经济损失和管理策略。
