Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, Volume 150, Issue 8, Page 1102-1114, September 2026.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Competitive exclusion of insect parasitic fungi: Enhanced metabolite biosynthesis in Beauveria bassiana and fatty acid production in Metarhizium robertsii during host coinfection.

Pesticide Biochemistry and Physiology
Microbial consortia, involving two or more microorganisms, have been explored for pest management purposes, despite concerns regarding competitive exclusion among entomopathogenic fungi that may undermine synergistic effects.

MrSkn7 Controls Sporulation, Cell Wall Integrity, Autolysis, and Virulence in Metarhizium robertsii [PDF]

Eukaryotic Cell, 2015
ABSTRACT Two-component signaling pathways generally include sensor histidine kinases and response regulators. We identified an ortholog of the response regulator protein Skn7 in the insect-pathogenic fungus Metarhizium robertsii , which we named MrSkn7. Gene deletion assays and functional characterizations

Empirical Support for the Pattern of Competitive Exclusion between Insect Parasitic Fungi

Journal of Fungi, 2021
Fungal entomopathogens are largely facultative parasites and play an important role in controlling the density of insect populations in nature. A few species of these fungi have been used for biocontrol of insect pests.

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 582-594, September 2026.
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.

Production of Helvolic Acid in Metarhizium Contributes to Fungal Infection of Insects by Bacteriostatic Inhibition of the Host Cuticular Microbiomes

Microbiology Spectrum, 2022
The nortriterpenoid helvolic acid (HA) has potent antibiotic activities and can be produced by different fungi, yet HA function remains elusive. Here, we report the chemical biology of HA production in the insect pathogen Metarhizium robertsii.

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, Volume 82, Issue 8, Page 7794-7808, August 2026.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Medium supplemented with insect pupae powder to induce growth of Beauveria bassiana and Metarhizium robertsii and the pathogenicity of Metarhizium robertsii

Revista Colombiana de Entomología, 2023
The use of insect cuticle is a viable option to induce the growth of entomopathogenic fungi. Spodoptera frugiperda (Sf) and Heliothis virescens (Hv). Pupal powder was obtained, which was added to enrich the Potato Dextrose Agar (PDA) culture medium at ...

Fusarium sacchari 14‐3‐3 Protein FsBmh1 Sequesters a Novel Elicitor FsEcm33 to Evade Host Immunity

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
When the elicitor FsEcm33 is sprayed onto Nicotiana benthamiana leaves, it enters the apoplast, triggering PAMP‐triggered immunity (PTI) that depends on NbRE02, NbBAK1, and NbSOBIR1. However, upon Fusarium sacchari infection, FsBmh1 binds FsEcm33 to prevent its localization on the cell surface, escaping PTI to allow colonization.
