The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Chaetotaxy of three nymphal instars of an ischnoceran louse, Aegypoecus perspicuus (Phthiraptera: Insecta) [PDF]

open access: yes, 2012
The present study on three nymphal instars of Aegypoecus perspicuus indicated that these differ from each other not only an size, abdominal segmentation, chitinization but also in the number of setae occurring on head, thorax and abdomen.

Phylogenomics reveals the timescale of diversification in Amblycera

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 540-553, July 2025.
Next‐generation sequencing changes the higher taxonomy of Amblycera (Insecta: Phthiraptera). Families Trimenoponidae and Gyropidae merge into Gyropidae; Trinotonidae is a separate family; several genera are paraphyletic. The ancestral host of Amblycera was likely a bird; Amblycera switched to mammals twice.

New record of the chewing louse Myrsidea dissimilis (Kellogg, 1896) (Phthiraptera: Menoponidae) parasitizing a Purple Martin, Progne subis (Linnaeus, 1758) (Passeriformes: Hirundinidae) in Amazonas, Brazil

open access: yesEntomological Communications, 2023
The chewing lice are obligatory ectoparasites of birds and mammals distributed worldwide. From an expedition to Comaru Island, Brazilian Amazon, a chewing louse parasitizing a Purple Martin [Progne subis (Linnaeus, 1758)], a Neotropical migrant, was ...

Avian Afterlives: Integrative Taxonomy of Hippoboscid Flies (Diptera) From Citizen‐Reported Bird Carcasses Reveals a New Species and Host–Parasite Diversity in Singapore

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
Biodiversity science depends on rigorous characterization of species diversity and ecological roles, yet the ecology of many invertebrate species remains virtually unknown. One pragmatic way to change this is to make use of deceased animals and their companions, such as by salvaging and examining carcasses reported by citizen scientists.
