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

Insects, Год журнала: 2025, Номер 16(2), С. 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. This study aimed collect new virulent entomopathogenic fungi (EPF) Kazakhstan show promise controlling Colorado potato beetle (CPB) populations under conditions. Local could be abiotic biotic factors environment which survive. findings this should provide insights into species EPF inhabit a specific region Kazakhstan, examining their traits regional climate, soil composition, biological diversity.

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

Fungal ecology, Год журнала: 2023, Номер 67, С. 101304 - 101304

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.

Abstract The black timber bark beetle ( Xylosandrus germanus ) is a strongly invasive ambrosia and an important forest pest in Slovakia. This closely associated with symbiotic fungi used as its food source. We investigated the X. adults In this study, Beauveria bassiana , B. pseudobassiana Clonostachys rosea Fusarium oxysporum Ophiostoma quercus Phaeoacremonium scolyti Talaromyces amestolkiae were isolated identified by morphological molecular analyses. fungus was most frequently from living beetles, while entomopathogenic commonly dead beetles. descriptions of based on isolates surface are provided.

Endophytic Beauveria bassiana in sugarcane and associated Eldana saccharina host plants in South Africa

Abstract Eldana saccharina Walker is a problematic sugarcane stalk borer pest in South Africa. Twenty-eight genotypes ( Saccharum spp. hybrids) and seven different species of host plants E. were surveyed for the presence endophytic Beauveria bassiana sensu lato s.l. ). Collectively, 326 plant samples (roots, stems, or leaves) collected from five locations sugarcane-producing areas (KwaZulu-Natal; Africa). Following surface disinfection, 128 fungal colonies morphologically resembling isolated internal tissues. The sequence analysis transcribed spacer region confirmed that 13 representative isolates B. bassiana. s.l . Eight recovered natural plants, 120 stem parts (top node, top internodes, bottom internode). Endophytic 22 28 surveyed. number obtained differed significantly, with more than internodes. Furthermore, N31 N41 yielded all sampled, while harbored no isolates. This study demonstrates first time occurrence strains
