TcFur1, a furin 1 ortholog in Tribolium castaneum, regulates reproduction and carbohydrate metabolism without affecting lipid homeostasis

open access: yesInsect Molecular Biology, EarlyView.
TcFur1, a furin 1 ortholog in Tribolium castaneum, is highly expressed in pupae and declines in adults. TcFur1 knockdown reduces oviposition but does not alter triacylglycerol levels or total lipase activity. TcFur1 knockdown increases circulating trehalose and decreases expression of insulin‐like peptides and the AKH receptor.

Propager, contaminer et infecter à travers les âges [PDF]

open access: yes, 2020
« Si je cherche une formule commode qui résume l’époque […] dans laquelle j’ai été élevé, j’espère avoir trouvé la plus expressive en disant : C’était l’âge d’or de la sécurité ». Ces mots sont ceux de l’écrivain viennois Stefan Zweig, mais nombreux sont

A Glial Interplay Regulates Junctional Architecture at the Blood–Brain Barrier of Drosophila

open access: yesGlia, Volume 75, Issue 1, January 2027.
Drosophila perineurial glia are required for septate junction formation at the blood–brain barrier. Glucose transport across the blood–brain barrier is maintained in the absence of perineurial glia. Perineurial glia ablation increases glucose‐only diet sensitivity.

Biological parameters of larvae, nymphs, and engorged females of Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae) obtained from artificial and successive infestations on Oryctolagus cuniculus (Linnaeus, 1758) (Lagomorpha: Ochotonidae) Parâmetros biológicos de larvas, ninfas e fêmeas ingurgitadas de Amblyomma cajennense (Fabricius, 1787) (Acari:Ixodidae) obtidas de infestações artificiais e sucessivas em Oryctolagus cuniculus (Lagomorpha:Ochotonidae)

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
The development of acquired resistance to Amblyomma cajennense ticks was evaluated. A total of 18 rabbits were uniformly distributed into three groups named GL, GN, and GA that were submitted to three consecutive infestations with, respectively, larvae ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 4, Page 759-773, December 2026.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

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

open access: yesPhysiological Entomology, Volume 51, Issue 4, Page 575-583, December 2026.
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.

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...
