A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

open access: yesPest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Potential mechanisms implied in tick infection by arboviruses and their transmission to vertebrate hosts

open access: yesIntegrative Zoology, Volume 20, Issue 2, Page 315-330, March 2025.
We summarize the recent progress in understanding defense mechanisms in specific tissues or sites that are encountered by arboviruses and discuss their possible roles in virus infection or transmission. Abstract Ticks can transmit many pathogens, including arboviruses, to their vertebrate hosts.
