Philornis downsi - a recently discovered parasite on the Galapagos archipelago - a threat for Darwin's finches?

Ibis, 2002
The obligate dipterian bird parasite Philornis downsi and the facultative parasitic fly Sarcodexia lambens were, until recently, unknown on the Galapagos archipelago. The first sign of parasitism of P.

Invasive parasites, habitat change and heavy rainfall reduce breeding success in Darwin's finches. [PDF]

PLoS ONE, 2014
Invasive alien parasites and pathogens are a growing threat to biodiversity worldwide, which can contribute to the extinction of endemic species. On the Galápagos Islands, the invasive parasitic fly Philornis downsi poses a major threat to the endemic ...

Temporal and spatial variation in sex-specific abundance of the avian vampire fly (Philornis downsi). [PDF]

Parasitol Res, 2022
AbstractUnderstanding the range and behaviour of an invasive species is critical to identify key habitat areas to focus control efforts. Patterns of range use in parasites can differ temporally, across life stages and between sexes. The invasive avian vampire fly,Philornis downsi, spends the larval stage of its life within bird nests, feeding on ...

Behavior of the Avian Parasite Philornis downsi (Diptera: Muscidae) in and Near Host Nests in the Galapagos Islands. [PDF]

J Insect Behav, 2021
AbstractThe Avian Vampire Fly, Philornis downsi, has invaded the Galapagos Islands, where it causes high mortality of endemic and native landbird species, including most species of Darwin’s finches. Control methods are under development, but key information is missing about the reproductive biology of P.

First record of the fungus Entomophthora infecting Philornis downsi, an invasive fly in the Galapagos Islands

The vampire y Philornis downsi is an obligate bird parasite that was introduced into the Galapagos Islands, probably accidentally from mainland Ecuador. Subsequently, the y dispersed to most islands in the archipelago, negatively impacting endemic land-

The genome sequence of the avian vampire fly (Philornis downsi), an invasive nest parasite of Darwin's finches in Galápagos. [PDF]

G3 (Bethesda), 2022
Abstract The invasive avian vampire fly (Philornis downsi, Diptera: Muscidae) is considered one of the greatest threats to the endemic avifauna of the Galápagos Islands. The fly larvae parasitize nearly every passerine species, including Darwin’s finches. Most P.
