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

Medical and Veterinary Entomology, EarlyView.
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.

The Regulatory Effect of Histone Deacetylase (HDAC) 1 and 2 on iNOS, IL‐6, TNF‐α and IL‐10 Expression in Canine Macrophages Infected With Leishmania infantum

Parasite Immunology, Volume 48, Issue 4, April 2026.
ABSTRACT Zoonotic visceral leishmaniasis is caused by Leishmania (Leishmania) infantum. Dogs are considered the most critical urban reservoirs of L. (L.) infantum due to their high infection rate and direct transmission to humans. The parasite has developed mechanisms to evade the host's defence system by inhibiting macrophage activation, thereby ...

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

European Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.
