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 ...

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

J Insect Behav, 2021
The 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.

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

Parasitol Res, 2022
Understanding 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.

Timing of infestation influences virulence and parasite success in a dynamic multi-host-parasite interaction between the invasive parasite, Philornis downsi, and Darwin's finches. [PDF]

Oecologia, 2021
Recently commenced host–parasite interactions provide an excellent opportunity to study co-evolutionary processes. Multi-host systems are especially informative because variation in virulence between hosts and temporal changes provides insight into ...

Genomic Insights into the Successful Invasion of the Avian Vampire Fly (Philornis downsi ) in the Galápagos Islands. [PDF]

Mol Biol Evol
Invasive species disrupt island ecosystems, posing significant threats to native species. The avian vampire fly (Philornis downsi), introduced into the Galápagos Islands, has become a major threat to endemic birds including Darwin’s finches, yet the ...

Comparative metabolomics reveal developmental and ecological plasticity in the invasive parasite Philornis downsi (Diptera: Muscidae) from the Galapagos Islands. [PDF]

J Insect Sci
Invasive species pose a critical threat to biodiversity, often endangering ecologically naive endemic fauna. The avian vampire fly, Philornis downsi Dodge & Aitken, 1968 (Diptera: Muscidae), a semi-hematophagous ectoparasite introduced to the Galápagos ...

Introduced parasite changes host phenotype, mating signal and hybridization risk: Philornis downsi effects on Darwin's finch song. [PDF]

Proc Biol Sci, 2019
Introduced parasites that alter their host's mating signal can change the evolutionary trajectory of a species through sexual selection. Darwin's Camarhynchus finches are threatened by the introduced fly Philornis downsi that is thought to have ...

Economic costs of biological invasions in Ecuador: the importance of the Galapagos Islands [PDF]

NeoBiota, 2021
Biological invasions, as a result of human intervention through trade and mobility, are the second biggest cause of biodiversity loss. The impacts of invasive alien species (IAS) on the environment are well known, however, economic impacts are poorly ...

Behavioral Responses of the Invasive Fly Philornis downsi to Stimuli from Bacteria and Yeast in the Laboratory and the Field in the Galapagos Islands. [PDF]

Insects, 2019
Philornis downsi (Diptera: Muscidae) is a nest parasitic fly that has invaded the Galapagos archipelago and exerts an onerous burden on populations of endemic land birds. As part of an ongoing effort to develop tools for the integrated management of this
