First report of the Philornis torquans complex in adult birds in continental Ecuador: Is parasitism by Philornis being underestimated?

open access: yesRevista Mexicana de Biodiversidad, 2022
Myiasis by Philornis is a usual phenomenon in Neotropical birds. Philornis larvae are hematophagous and are known to affect both nestlings and adults. Still, parasitism in adults seems opportunistic and has been poorly studied compared to parasitism in ...

Multi-level determinants of parasitic fly infection in forest passerines. [PDF]

open access: yesPLoS ONE, 2013
The study of myiasis is important because they may cause problems to the livestock industry, public health, or wildlife conservation. The ecology of parasitic dipterans that cause myiasis is singular, as they actively seek their hosts over relatively ...

Population dynamics of an invasive bird parasite, Philornis downsi (Diptera: Muscidae), in the Galapagos Islands. [PDF]

open access: yesPLoS ONE, 2019
The invasive parasitic fly, Philornis downsi (Muscidae), is one of the greatest threats to the avifauna of the Galapagos Islands. The larvae of this fly feed on the blood and tissues of developing nestlings of at least 18 endemic and native birds.

Kinship Analysis Confirms Tolerant Galapagos Mockingbirds Are a Source of Nest Flies That Threaten Darwin's Finches. [PDF]

open access: yesMol Ecol
ABSTRACT Host species have evolved different strategies for dealing with parasites. ‘Vulnerable’ hosts, which suffer reduced fitness from parasites, are under selection to evolve defences. ‘Tolerant’ hosts, by contrast, avoid reductions in fitness by mitigating parasite damage.

Parental care in the Small Tree Finch Camarhynchus parvulus in relation to parasitism and environmental factors. [PDF]

open access: yesIbis (Lond 1859), 2021
The parental food compensation hypothesis suggests that parents may compensate for the negative effects of parasites on chicks by increased food provisioning. However, this ability differs widely among host species and may also depend on ecological factors such as adverse weather conditions and habitat quality.

Evidence for rapid downward fecundity selection in an ectoparasite (Philornis downsi) with earlier host mortality in Darwin's finches. [PDF]

open access: yesJ 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 ...

Under adverse conditions, older small tree finch males (Camarhynchus parvulus) produce more offspring than younger males. [PDF]

open access: yesEthology, 2020
In many bird species, females paired with older males have a higher breeding success. Small tree finches are heavily affected by an invasive nest parasite. Nests of older males had more fledglings than those of younger males. However, the difference in breeding success disappeared when parasites were experimentally reduced with the insecticide ...

First record of Philornis glaucinis Dodge & Aitken, 1968 (Diptera: Muscidae) in Thalurania glaucopis Gmelin, 1788 (Aves: Trochilidae) [PDF]

open access: yesBiotemas, 2010
From the groups causing myiasis, the genus Philornis Meinert, 1890 appears as the only representative of the family Muscidae, obligatorily associated with birds.
