Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.

Culicoides biting midges (Diptera: Ceratopogonidae) feeding on donkeys in the United Kingdom, with reference to the risk of transmission and persistence of African horse sickness virus

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 560-567, September 2026.
Culicoides biting midges were collected at a donkey sanctuary in the United Kingdom using UV light‐suction traps. Culicoides were found in abundance and all specimens were identified to species level. Blood‐feeding on donkeys was confirmed by polymerase chain reaction (PCR) and sequencing of host bloodmeals. Donkeys could play a significant role in the
