The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

Riboflavin induces Metarhizium spp. to produce conidia with elevated tolerance to UV-B, and upregulates photolyases, laccases and polyketide synthases genes [PDF]

, 2018
Aims: The effect of nutritional supplementation of two Metarhizium species with riboflavin (Rb) during production of conidia was evaluated on (i) conidial tolerance (based on germination) to UV-B radiation and on (ii) conidial expression following UV-B ...

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

Advanced 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

The divergence of DHN-derived melanin pathways inMetarhizium robertsii

World Journal of Microbiology and Biotechnology
AbstractThe important role of dihydroxynaphthalene-(DHN) melanin in enhancing fungal stress resistance and its importance in fungal development and pathogenicity are well-established. This melanin also aids biocontrol fungi in surviving in the environment and effectively infecting insects.

Assessment of bio-formulations of indigenous strains of Bacillus thuringiensis, Metarhizium robertsii and Metarhizium majus for management of the rhinoceros beetle, Oryctes rhinoceros L., in field

Egyptian Journal of Biological Pest Control, 2023
Background Among all the coconut pests, rhinoceros beetle causes acute and serious damage to coconut palm. Management of this pest is very difficult due to its nocturnal activity, and also, it damages the emerging leaf inside the bud.

Control of Woolly Apple Aphid (Eriosoma lanigerum) by Augmenting Earwigs (Forficula auricularia) in the Canopy of Apple Trees

Entomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 61-73, January 2026.
Apple trees provisioned with five earwigs and a refuge made a small but not significant contribution to woolly apple aphid control. ABSTRACT Woolly apple aphid, Eriosoma lanigerum (Hausmann), is a damaging pest of apple (Malus domestica F.) found in most regions of the world where apples grow.

Transient anoxia during Metarhizium robertsii growth increases conidial virulence to Tenebrio molitor

Journal of Invertebrate Pathology, 2018
Little is known about the phenotypic effects of hypoxia and transient anoxia on the virulence of an entomopathogenic fungus. Conidia of Metarhizium robertsii were produced on: (1) potato dextrose agar medium (PDA) under normoxia; (2) PDA medium under continuous hypoxia; (3) PDA medium under transient anoxia; and (4) minimal medium with lactose (MML ...

Alternative transcription start site selection in Mr-OPY2 controls lifestyle transitions in the fungus Metarhizium robertsii

Nature Communications, 2017
The fungus Metarhizium robertsii can act as a saprophyte, plant symbiont and insect pathogen. Here, the authors show that the use of alternative transcription start sites controls the expression of membrane protein Mr-OPY2, which in turn modulates the ...

Land-Use Type Drives Soil Population Structures of the Entomopathogenic Fungal Genus Metarhizium

Microorganisms, 2021
Species of the fungal genus Metarhizium are globally distributed pathogens of arthropods, and a number of biological control products based on these fungi have been commercialized to control a variety of pest arthropods. In this study, we investigate the

Tri‐trophic interactions of soil mite Sancassania polyphyllae (Acari: Acaridae) with fungal biocontrol agents

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Mycophagous invertebrates can significantly impact the efficacy of fungal biocontrol agents; yet the interaction between these agents and Sancassania polyphyllae (Acari: Acaridae), commonly found in soil ecosystems, remains poorly understood. Our study demonstrates that Sa.
