我们报告了在北方阿尔伯塔的两栖动物种群中0.9%的总体患病率由Lucilia silvarum myeloma。在1998-1999年期间，我们记录了L。森林蛙在森林蛙（Rana sylvatica）、北方合唱蛙（Pseudacris maculata）、北方蟾蜍（Bufo boreas boreas）和加拿大蟾蜍（B.偏身畸形）。我们相信这是第一次记录这种寄生虫从北方和加拿大蟾蜍。几乎所有的L.在北美森林寄生表明，糠虾对无尾类宿主是致命的。在这里，我们提供了第一个记录的成年个体从2个物种（林蛙和北方蟾蜍）幸存的侵扰。虽然我们在1996年至2006年期间在阿尔伯塔积极捕捉和检查两栖动物，但我们只在1998年和1999年发现了寄生虫。这是最北的记录无尾两栖动物感染这种寄生虫。
We report myiasis by Lucilia silvarum with an overall prevalence of 0.9% in amphibian populations in boreal Alberta. In the period 1998–1999, we documented L. silvarum infestations in wild populations of wood frog (Rana sylvatica), boreal chorus frog (Pseudacris maculata), boreal toad (Bufo boreas boreas), and Canadian toad (B. hemiophrys). We believe this is the first record of this parasite from boreal and Canadian toads. Almost all previous records of L. silvarum parasitism in North America indicate that myiasis is fatal to an anuran host. Here, we provide the first record of adult individuals from 2 species (wood frog and boreal toad) surviving infestations. Although we actively captured and examined amphibians in Alberta from 1996 to 2006, we only found parasitism in 1998 and 1999. This is the most northerly record of anuran infestations by this parasite.
