Intraspecific Competition Promotes Oviposition During Host Egg Incubation in the Parasitic Fly Philornis downsi [PDF]
Ecology and EvolutionAvian biodiversity declines are increasingly linked to invasive parasites threatening local bird populations that lack evolved defenses. The level of virulence in these interactions, in turn, influences the parasites' own fitness and drives co ...

Epigenetic effects of parasites and pesticides on captive and wild nestling birds [PDF]
Ecology and Evolution, 2021 Anthropogenic changes to the environment challenge animal populations to adapt to new conditions and unique threats. While the study of adaptation has focused on genetic variation, epigenetic mechanisms may also be important. DNA methylation is sensitive

Avian vampire fly (Philornis downsi) mortality differs across Darwin’s finch host species [PDF]
Scientific Reports, 2021 In invasive parasites, generalism is considered advantageous during the initial phase of introduction. Thereafter, fitness costs to parasites, such as host-specific mortality, can drive parasites towards specialism to avoid costly hosts.

Trypanosomatids Detected in the Invasive Avian Parasite Philornis downsi (Diptera: Muscidae) in the Galapagos Islands [PDF]
Insects, 2020 Alien insect species may present a multifaceted threat to ecosystems into which they are introduced. In addition to the direct damage they may cause, they may also bring novel diseases and parasites and/or have the capacity to vector microorganisms that ...

Persistence of the invasive bird-parasitic fly Philornis downsi over the host interbreeding period in the Galapagos Islands [PDF]
Scientific Reports, 2022 Many parasites of seasonally available hosts must persist through times of the year when hosts are unavailable. In tropical environments, host availability is often linked to rainfall, and adaptations of parasites to dry periods remain understudied.

Innovations in invasive parasite control: enhancing nest treatment techniques to combat the threat of the avian vampire fly Philornis downsi in Galapagos [PDF]
Frontiers in Conservation ScienceThe invasive parasitic nest fly Philornis downsi poses a severe threat to the conservation of Galapagos’ endemic landbirds, including Darwin’s finches.

From dispenser to nest: collection of fumigated material repels parasites across behavioural traits in Darwin’s finches [PDF]
BMC ZoologyIn the midst of a biodiversity crisis, it is important to conserve diversity at all levels, including species, genetic, and behavioural diversity. Animals with different behavioural traits can interact with their environment in distinct ways; hence, the ...

Brazilian Journal of Biology, 2003 Passeromyia Rodhain & Villeneuve and Philornis Meinert are the only known Muscidae whose larvae are parasites of birds. Passeromyia is known from the Old World and Philornis from the New World. Opinions on the relations between these two genera and their

Genetic admixture predicts parasite intensity: evidence for increased hybrid performance in Darwin's tree finches [PDF]
Royal Society Open Science, 2019 Hybridization can increase adaptive potential when enhanced genetic diversity or novel genetic combinations confer a fitness advantage, such as in the evolution of anti-parasitic mechanisms. Island systems are especially susceptible to invasive parasites

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