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.

Taxonomic Study of Sixteen Unrecorded and Five New Species of Hypocreales from the Korean Marine Environment

mycolabadmin

Researchers in South Korea discovered 21 previously unknown species of fungi living in marine environments like ocean sediments and seaweed. They identified 5 completely new species and 16 species that had never been recorded in Korea before. These fungi belong to a group called Hypocreales that can be found in various ocean habitats and may have potential uses in medicine and agriculture.

Insecticidal Action of Local Isolates of Entomopathogenic Fungi Against Bactrocera oleae Pupae

Olive farmers in Mediterranean countries struggle with the olive fruit fly, which damages olives and reduces oil production. Researchers tested special fungi that naturally infect and kill insects to see if they could control this pest at the soil stage when fly pupae are developing underground. Several fungal species, especially Beauveria bassiana, were effective at reducing survival of emerged adult flies by about 40% compared to untreated flies. This offers a promising natural alternative to chemical pesticides that can harm olive oil quality and lose effectiveness over time.

A mycovirus enhances fitness of an insect pathogenic fungus and potentially modulates virulence through interactions between viral and host proteins

mycolabadmin

Scientists discovered a virus that infects Beauveria bassiana, a fungus used to control pests naturally. This virus actually helps the fungus by making it produce more spores, survive harsh conditions like sunlight and heat, and kill target insects faster. The virus does this by interacting with specific fungal proteins that control reproduction, stress response, and virulence. This discovery could lead to better biological pest control products that are more effective and reliable than current options.

Volatile Semiochemicals Emitted by Beauveria bassiana Modulate Larval Feeding Behavior and Food Choice Preference in Spodoptera frugiperda (Lepidoptera: Noctuidae)

mycolabadmin

Researchers discovered that a beneficial fungus called Beauveria bassiana produces odorous chemicals that can discourage pest insects from eating crops. When certain strains of this fungus release their characteristic smell (particularly a compound called 3-methylbutanol), larvae of the fall armyworm pest eat less and avoid treated plants. Interestingly, the plants themselves respond by producing defensive compounds when exposed to these fungal odors. This finding suggests a new approach to pest control that harnesses the natural chemical communication between fungi, plants, and insects.

A Case of Allergic Bronchopulmonary Mycosis Caused by Cordyceps farinosa, a Species of Caterpillar Fungi

mycolabadmin

A woman developed a serious respiratory condition called allergic bronchopulmonary mycosis caused by Cordyceps farinosa, a fungus that normally infects insect larvae. She worked in a laboratory breeding mice in a mountainous area and developed persistent cough and congestion. Doctors identified the fungus using DNA testing and treated her by removing the fungal material from her airways and removing her from the workplace, which led to complete recovery.

The Last of Them: Entomopathogenic Effect of Akanthomyces muscarius on the Scale Insect Pest Toumeyella parvicornis Under Laboratory Conditions, a Potential Biological Control Candidate

mycolabadmin

Scientists tested a fungus called Akanthomyces muscarius as a natural way to control an invasive pest called the tortoise scale insect that damages stone pine trees in Europe. In laboratory experiments, the fungus effectively infected and killed these insects, showing much better results than commercial fungal products. This research suggests the fungus could be used as an environmentally-friendly alternative to chemical pesticides for protecting pine trees in urban areas.

Development of Biphasic Culture System for an Entomopathogenic Fungus Beauveria bassiana PfBb Strain and Its Virulence on a Defoliating Moth Phauda flammans (Walker)

mycolabadmin

Researchers developed an efficient two-stage fermentation process to mass-produce Beauveria bassiana PfBb, a fungus that kills defoliating moths damaging Ficus trees. The first stage grows the fungus in liquid to produce active spores, which are then transferred to solid substrates to produce hardy, long-lasting conidia. The optimized process produces high quantities of effective fungal spores that can be stored at refrigerator temperature for over a year while maintaining their pest-killing ability.

Development of Mycoinsecticides: Advances in Formulation, Regulatory Challenges and Market Trends for Entomopathogenic Fungi

mycolabadmin

This review explores fungal-based insecticides as environmentally friendly alternatives to chemical pest control. These products use naturally occurring fungi that infect and kill insects through direct contact, making them effective against many crop pests. The review covers different formulation types, product development challenges, and regulatory approval processes in major markets worldwide.

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

mycolabadmin

Researchers discovered a naturally occurring fungus called Mucor hiemalis that can kill Evergestis extimalis, a pest that damages rapeseed crops. They identified optimal growing conditions for this fungus and tested its effectiveness against different life stages of the pest. The fungus proved highly effective, especially against younger larvae, offering a promising natural alternative to chemical pesticides for crop protection.
