Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.

Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide‐susceptible and resistant strains

Pest Management Science, Volume 82, Issue 2, Page 1618-1628, February 2026.
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.
