Alien Invasion: Biology of Philornis Flies Highlighting Philornis downsi, an Introduced Parasite of Galápagos Birds

The muscid genus Philornis comprises approximately 50 described species of flies, nearly all of which are obligate parasites of nestling birds. Philornis species are native to the Neotropics and widely distributed from Florida to Argentina. Most research on this group has focused on P. downsi, which was introduced to the Galápagos Islands in the late twentieth century. Although Philornis parasitism kills nestlings in several native host species, nowhere do the effects seem more severe than in P. downsi in the Galápagos. Here, we review studies of native and introduced Philornis in an attempt to identify factors that may influence virulence and consider implications for the conservation of hosts in the Galápagos.

外星人入侵:费洛尼斯苍蝇生物学重点介绍了加洛帕戈斯鸟类的寄生虫费洛尼斯·唐斯

费洛尼斯属粘液虫属包括大约50种上述蝇类,几乎所有蝇类都是专性的雏鸟寄生虫。Philornis物种是新热带地区的原生物种,并从佛罗里达州到阿根廷广泛分布。关于这一群体的大多数研究都集中在P. downsi上,物种在20世纪后期被引入加拉帕戈斯群岛。尽管Philornis寄生虫杀死了几种本地寄主物种的雏鸟,但在加拉帕戈斯群岛上,这种现象似乎没有比P. downsi更为严重的了。在这里,我们回顾了本土和引进的Philornis的研究 试图确定可能影响毒力的因素,并考虑对加拉帕戈斯群岛寄主保护的影响。
