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

Insect 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

Phylogenomics reveals the timescale of diversification in Amblycera

Systematic 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.

Diversity of lice and flea‐ and lice‐borne pathogens in free‐ranging dogs in Uzbekistan

Medical and Veterinary Entomology, Volume 39, Issue 1, Page 216-222, March 2025.
Lice (Trichodectes canis, Linognathus africanus and Bovicola bovis) and fleas were collected from dogs across five regions of Uzbekistan and subjected to molecular analysis. Molecular screening detected Dipylidium caninum and Bartonella spp. in fleas, while Rickettsia spp. were identified in both fleas and lice.

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

Journal 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.
