Potential of Beauveria Species Isolated from Southern Kazakhstan for Controlling Colorado Potato Beetle (Leptinotarsa decemlineata) Populations Under Arid Conditions

Insects, Journal Year: 2025, Volume and Issue: 16(2), P. 176 - 176

Environmentally sound insect pest management strategies require continuous isolation and identification of effective biocontrol agents from different ecosystems. The quest for fungal isolates that are adapted to high temperatures is particularly significant, as they hold the potential produce mycoinsecticides highly in semiarid arid areas.

Hidden diversity within Beauveria and Metarhizium – Comparing morphology, barcoding, multilocus phylogenies and whole-genome sequences

Fungal ecology, Journal Year: 2023, Volume and Issue: 67, P. 101304 - 101304

Published: Nov. 16, 2023

Accurately identifying entomopathogenic fungi is crucially important, but the current approach of analysing four genes might not provide sufficient resolution. In this study, we investigated different resolution provided by multilocus phylogenies and approaches based on whole genome sequence data. Fungi were isolated from soil samples that collected five vegetation types (dry sclerophyll forest, agricultural grassland, rainforest, suburban parkland, sugar cane fields) across habitat in southeast Queensland. Three pests used as live baits, cotton stainer bug, diamondback moth, rust-red flour beetle. Whole-genome sequencing was conducted for all 83 isolates recovered, ITS2 region extracted assemblies to make initial species identifications with UNITE database.

Phenotypic variation and genomic variation in insect virulence traits reveal patterns of intraspecific diversity in a locust‐specific fungal pathogen

Journal of Evolutionary Biology, Journal Year: 2023, Volume and Issue: 36(10), P. 1438 - 1454

Published: Sept. 13, 2023

Intraspecific pathogen diversity is crucial for understanding the evolution and maintenance of adaptation in host-pathogen interactions. Traits associated with virulence are often a significant source variation directly impacted by local selection pressures. The specialist fungal entomopathogen, Metarhizium acridum, has been widely implemented as biological control agent locust pests tropical regions world. However, few studies have accounted natural intraspecific phenotypic genetic variation. Here, we examine nine isolates M. acridum spanning known geographic distribution, terms (1) towards two species, (2) growth rates on three diverse nutrient sources, (3) comparative genomics to uncover genomic variability. Significant variability patterns was shown among isolates, suggesting ecological specialization. Different were between indicative potential host preference. Additionally, high level observed, revealing increased subtilisin-like proteases from Pr1 family. These results culminate first in-depth analysis regarding multiple facets offering opportunities understand critical evolutionary drivers pathogens.
