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

open access: yesInsect Molecular Biology, EarlyView.
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

Origin, Divergence and Migration Routes of Psyllids of the Cacopsylla pruni Complex (Hemiptera: Psylloidea) Inferred by Approximate Bayesian Computation Methods

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Population genetics is essential to decipher the evolutionary history of pests and insect vectors from both a theoretical point of view and to predict and mitigate the future of epidemics. We attempt to shed light on the evolutionary history and phylogeography of two cryptic psyllid species (namely, A and B) of the Cacopsylla pruni complex,

Vector Biology of the Soft Scales Parthenolecanium corni (Bouché) and Parthenolecanium persicae (Fabricius) (Hemiptera: Coccidae) With Grapevine Leafroll‐Associated Viruses and Grapevine Virus A

open access: yesJournal of Applied Entomology, Volume 149, Issue 3, Page 405-416, April 2025.
ABSTRACT Controlled experiments were conducted to enrich our knowledge on the transmission of different grapevine leafroll‐associated ampeloviruses (GLRaV‐1, ‐2, ‐3 and ‐4) by Parthenolecanium corni scale insect and to look for vector ability of Parthenolecanium persicae. GLRaV‐1 and the vitivirus GVA were transmitted by P.
