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

mycolabadmin

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.

Bioprospecting of four Beauveria bassiana strains and their potential as biological control agents for Anastrepha ludens Loew 1873 (Diptera: Tephritidae)

mycolabadmin

Researchers tested four strains of a beneficial fungus called Beauveria bassiana from Mexico to see if they could control the Mexican fruit fly, a major pest that damages mango and orange crops. The fungus naturally infects insects and kills them. Tests showed that all four strains were very effective at killing adult fruit flies, with the best performance at higher spore concentrations. These locally adapted fungal strains may work better than imported alternatives for farmers in the Veracruz region.

Toxicity Assay and Pathogenic Process Analysis of Clonostachys rogersoniana Infecting Cephalcia chuxiongica

mycolabadmin

A destructive pine forest pest called Cephalcia chuxiongica causes significant damage to forests in China. Researchers discovered that a fungus called Clonostachys rogersoniana can effectively kill this pest by uniquely infecting it through breathing holes called spiracles. This fungus-based biological control offers an environmentally friendly alternative to chemical pesticides, potentially protecting China’s forests while reducing chemical pollution.

Evaluating Beauveria bassiana Strains for Insect Pest Control and Endophytic Colonization in Wheat

mycolabadmin

Scientists tested three strains of a beneficial fungus called Beauveria bassiana to control crop-damaging insects and promote wheat growth. The best-performing strain, CBM1, successfully killed multiple types of pest insects and colonized wheat plants when applied to the soil. Wheat plants colonized with this fungus grew taller with longer roots and showed significantly better protection against fall armyworms, suggesting this fungus could be a valuable tool for sustainable, pesticide-free crop protection.

Toxicity Assay and Pathogenic Process Analysis of Clonostachys rogersoniana Infecting Cephalcia chuxiongica

mycolabadmin

Scientists discovered a fungus called Clonostachys rogersoniana that can kill a major pine forest pest. The fungus enters the pest through small breathing holes called spiracles, which is unusual compared to most fungal infections. Testing showed the fungus kills half the pest population in about 24 hours at relatively low concentrations. This discovery could help protect Chinese pine forests without using harmful chemical pesticides.

Isolation, Identification, Biological Characterization, and Pathogenicity of Entomopathogenic Fungus from the Larvae of the Evergestis extimalis (Scopoli) (Lepidoptera: Pyralidae)

mycolabadmin

Scientists discovered a fungus called Mucor hiemalis that naturally infects and kills a harmful rapeseed pest known as Evergestis extimalis. They identified the fungus, found the best conditions for growing it in the lab, and tested how well it kills the pest larvae at different life stages. The results show this fungus could be used as a natural, environment-friendly alternative to chemical pesticides for protecting rapeseed crops.
