RÉTENTION DES OVULES APRÈS OVULATION DANS LA CAVITÉ OVARIENNE DE LA CARPE HERBIVORE : COMPOSITION DES OVULES ET CAPACITÉ DE DÉVELOPPEMENT DES ŒUFS ET DES ALEVINS.

open access: yesKnowledge and Management of Aquatic Ecosystems, 2002
Pour étudier l’effet de rétention prolongée des ovules dans la cavité ovarienne (in vivo) de la carpe herbivore, des extractions d’ovules de 15 femelles (3 à 5,6 kg) ont eu lieu à différents intervalles de temps après ovulation (0, 30, 60, 90 et 120 min).

The influence of pupal colour on diapause and post‐diapause success in the swallowtail butterfly Papilio machaon

open access: yesPhysiological Entomology, EarlyView.
The swallowtail butterfly Papilio machaon has a brown‐ and green‐coloured morph, with the brown being more common in the diapausing generation. The darker colouration of brown pupae did not confer advantages for thermoregulation when developing, but they did have lower diapause metabolic rates.

Assessing the hidden risks of non‐thermal processing: Ultrasound‐induced toxicity of cashew apple juice in a zebrafish model

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7044-7055, September 2026.
Abstract Background High‐intensity ultrasound is widely advocated for the preservation of liquid foods; however, the potential formation or release of toxic compounds during processing remains under‐investigated. This study evaluated the toxicological profile of cashew apple juice processed by high‐intensity ultrasound (1250, 1875, and 2500 W;L⁻¹ ...

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 512-529, September 2026.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 551-559, September 2026.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...
