Effect of Selected Entomopathogenic Fungal Species on Embryonic Development of Ascaris suum (Nematoda)

mycolabadmin

Researchers tested five types of fungi that naturally attack insects to see if they could control Ascaris roundworm eggs that contaminate pig farms and pose health risks. While none of the fungi directly killed the eggs, two species (Isaria fumosorosea and Metarhizium robertsii) successfully slowed egg development and showed potential for controlling parasites. These fungi appear to work by producing toxic compounds and enzymes rather than by penetrating the egg shells directly.

Characterization and Virulence of Metarhizium anisopliae (Hypocreales: Clavicipitaceae) Isolates from Ecologically Distinct Soils Against Spodoptera litura (Lepidoptera: Noctuidae)

This study identified five native fungal strains (Metarhizium anisopliae) from Taiwanese soils that can kill the tobacco caterpillar pest (Spodoptera litura). The most effective strain, PT-01, showed strong ability to infect and kill caterpillar larvae, particularly at early life stages. The research demonstrates that these fungi could be developed into environmentally-friendly pest control alternatives to chemical pesticides, protecting crops while maintaining ecosystem health.

Genome Sequence, Comparative Genome Analysis, and Expression Profiling of the Chitinase GH18 Gene Family in Cordyceps javanica Bd01

mycolabadmin

Scientists sequenced the complete genome of Cordyceps javanica, a fungus used to control pest insects. They discovered that this fungus has an expanded family of 27 chitinase genes (GH18), which are enzymes that help the fungus penetrate insect exoskeletons. These genes show strong evolutionary conservation and stability, making them valuable for developing more effective natural pesticides and understanding how fungal biocontrol agents work.

First Record of Clonostachys rosea as an Entomopathogenic Fungus of the Cephus fumipennis (Hymenoptera: Cephidae) in China

mycolabadmin

Scientists in China discovered a fungus called Clonostachys rosea that naturally kills wheat stem sawfly larvae, a major pest damaging wheat crops. The fungus was isolated from infected larvae and tested for effectiveness against the pest. Laboratory tests showed the fungus can kill sawfly larvae at different concentrations, with the fastest effect at higher spore levels. This discovery offers a natural and environmentally friendly alternative to chemical pesticides for protecting wheat crops.

Biostimulant and Bioinsecticidal Effect of Coating Cotton Seeds with Endophytic Beauveria bassiana in Semi-Field Conditions

mycolabadmin

Researchers coated cotton seeds with a beneficial fungus called Beauveria bassiana to improve plant growth and reduce insect pests. The treated cotton plants grew taller, had more leaves, and accumulated more biomass than untreated plants. Additionally, these coated seeds significantly reduced populations of aphids that naturally infested the plants, offering a chemical-free approach to pest management for cotton farming.

Mitochondrial genome characterization, evolution and intron dynamics of the entomopathogenic genus Cordyceps

mycolabadmin

This research examined the genetic instruction manuals (mitochondrial DNA) of seven different Cordyceps fungal species. Scientists found that these fungi have varying amounts of genetic material, primarily due to differences in introns—sections that can be inserted or removed from genes. By comparing their genomes, researchers clarified how different Cordyceps species are related to each other evolutionarily, providing better tools for identifying and classifying these medically valuable fungi.

Two new Cordyceps-like species, Perennicordyceps zongqii sp. nov. (Polycephalomycetaceae) and Purpureocillium zongqii sp. nov. (Ophiocordycipitaceae), in Hypocreales from karst region of China

mycolabadmin

Scientists discovered two new types of specialized fungi in the karst regions of China that infect insects and live in soil. These fungi, named Perennicordyceps zongqii and Purpureocillium zongqii, were identified using genetic analysis and microscopic examination. The findings highlight how special cave and valley environments in karst regions support unique fungal species that haven’t been previously documented in these areas.

Geographic variation in fungal diversity associated with leaf spot symptoms of Coffea arabica in Yunnan, China

mycolabadmin

Researchers studied the different types of fungi found on coffee plant leaves in two regions of Yunnan, China. They discovered that the mountainous areas of Pu’er had more harmful fungi causing leaf spot disease, while the tropical lowlands of Xishuangbanna had more beneficial fungi that could naturally control pests. This information helps coffee farmers choose better disease management strategies based on their location’s unique environmental conditions.

Draft genome of Conoideocrella luteorostrata ARSEF 14590 (Clavicipitaceae), an entomopathogenic fungus with a wealth of biosynthetic and biocontrol potential

mycolabadmin

Scientists have sequenced the complete genome of a fungus that naturally kills elongate hemlock scale insects, pests that damage Christmas trees. The fungus contains genes for producing cephalosporin, a well-known antibiotic, and other bioactive compounds. This discovery opens new possibilities for using this fungus as a natural pest control method and potentially developing new medicines from its biological compounds.

Microcycle Conidia Production in an Entomopathogenic Fungus Beauveria bassiana: The Role of Chitin Deacetylase in the Conidiation and the Contribution of Nanocoating in Conidial Stability

mycolabadmin

Researchers developed a method to dramatically increase the production of fungal spores used for controlling crop-damaging insects like armyworms. By using a special growth medium and coating the spores with nanoscale particles, they created more stable and effective fungal pesticides that work faster and better in the field. This advance could make biological pest control more practical and affordable for farmers.
