الملخص
The content describes the discovery of a parasitoid wasp species that can infect and develop inside adult fruit flies, including the model organism Drosophila melanogaster. This is the first known wasp species that attacks the adult stage of a fly host.
The key highlights and insights include:
Parasitoid wasps are exceptionally diverse and can manipulate the physiology and behavior of their host organisms.
Nearly 200 described and provisional parasitoid species of drosophilids (fruit flies) have been identified, but none were previously known to attack the adult stage.
The newly discovered wasp species can be easily collected from backyard fly baits and has a broad geographic distribution in the eastern USA.
The researchers document the wasp's life history and unique host interactions, including egg-laying into and larval emergence from adult flies, and provide protocols to raise wasps from wild-caught host flies.
This discovery emphasizes the need for ongoing research investment in insect biodiversity and systematics, as parasitoid research can provide fundamental insights into immunity, metabolism, ecology, evolution, and behavior.
The wasp's association with the laboratory model organism D. melanogaster is expected to provide new research opportunities across the life sciences.

اقتباسات
"Parasitoid wasps are exceptionally diverse and use specialized adaptations capable of manipulating the physiology and behaviour of host organisms1."
"Despite a deep history of research attention and remarkable biodiversity, a wasp species that attacks and develops inside the adult stage of a fly host has not been described previously."
