     據外媒報道,受棲地喪失、野火和外來植物與昆蟲入侵等因素影響,夏威夷本土蜂數量大幅下降,9月30日美國聯邦公報(Federal Register)把7種黃面蜂或蒙面蜂列為瀕危物種。 
    美國魚類與野生動物管理局(United States Fishand Wildlife Service)指出,以其臉部有黃或白色標記命名的這些蜜蜂,過去在夏威夷和毛伊島(Maui)數量眾多。然而近期調查發現,跟美國其他地方多種野蜂及部分商業繁殖的蜜蜂一樣,夏威夷蜜蜂數量也出現驟減。
 
    部分原文報道如下:
 
    Seven types of bees once found in abundance in Hawaii but now facing extinction on Friday became the first bees to be added to the federal list of endangered and threatened species, according to U.S. wildlife managers.
 
    The listing decision, published on Friday in the Federal Register, classifies seven varieties of yellow-faced or masked bees as endangered, due to such factors as habitat loss, wildfires and the invasion of nonnative plants and insects.
 
    The bees, so named for yellow-to-white facial markings, once crowded Hawaii and Maui but recent surveys found their populations have plunged in the same fashion as other types of wild bees - and some commercial ones - elsewher in the United States, federal wildlife managers said.
