The Invasive Parasitic Fly Philornis downsi Is Threatening Little Vermilion Flycatchers on the Galápagos Islands [PDF]
Avian Conservation and Ecology, 2022 Populations of several species of birds endemic to the Galápagos Islands have declined during recent decades, including endemic Little Vermilion Flycatchers (Pyrocephalus nanus). Understanding the reasons for the low breeding success of this species is a

Naris deformation in Darwin’s finches: Experimental and historical evidence for a post-1960s arrival of the parasite Philornis downsi [PDF]
Global Ecology and Conservation, 2016 The rate of evolution depends on the strength of selection, which may be particularly strong for introduced parasites and their naive hosts. Because natural selection acts on phenotypes and because parasites can alter host phenotype, one fruitful ...

Evidence for rapid downward fecundity selection in an ectoparasite (Philornis downsi) with earlier host mortality in Darwin's finches. [PDF]
J Evol Biol, 2020 Frontal view of a female Philornis downsi, a myasis‐causing paraiste of Darwin's finches, whose body size, abdomen size, and fecundity have decreased c. 30% across 12 years as nestling hosts die at an ever younger age. Photo by Bradley Sinclair. Abstract Fecundity selection is a critical component of fitness and a major driver of adaptive evolution ...

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 Dodge and Aitken (Diptera: Muscidae) is an avian 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

Rearing Larvae of the Avian Nest Parasite, Philornis downsi (Diptera: Muscidae), on Chicken Blood-Based Diets. [PDF]
J Insect Sci, 2016 Captive rearing of insect pests is necessary to understand their biology and to develop control methods. The avian nest fly, Philornis downsi Dodge and Aitken, is a blood-sucking parasite during its larval stage and a serious threat to endemic birds in ...

Relationships among introduced parasites, host defenses, and gut microbiota of Galapagos birds
Ecosphere, 2018 Parasites can cause significant damage to their hosts. Hosts can reduce the damage that parasites cause by either resisting parasites (e.g., with an immune response) or tolerating parasites (e.g., with energy compensation). Recent work suggests that host‐
