Medical and Veterinary Entomology, EarlyView.Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Archives of Insect Biochemistry and Physiology, Volume 122, Issue 2, June 2026.This study reveals a “Microbiota‐Immune Axis” in Beauveria bassiana‐infected larvae, where gut dysbiosis positively correlates with systemic immunity in the fat body. Meanwhile, the hindgut exhibits immune tolerance, highlighting a tissue‐specific trade‐off between combating the pathogen and preserving the gut microbiome.
