This study tested different types of beneficial fungi to control olive fruit flies, which are major pests in Mediterranean olive groves. Researchers found that several fungi species, particularly those from the Aspergillus genus, can effectively kill olive fly pupae when applied to soil. The results suggest these fungi could be developed into biological pesticides to protect olive crops without harmful chemical insecticides.

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

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.

Beauveria bassiana associated with a novel biomimetic hydrogel to control Aedes albopictus through lure and kill ovitraps

Researchers developed a new gel-based trap that combines a natural fungus (Beauveria bassiana) with specially designed hydrogels to control Asian tiger mosquitoes (Aedes albopictus), which spread dangerous diseases like Zika and dengue. The gel traps work by both mechanically trapping mosquito eggs and infecting them with the fungus, achieving over 90% effectiveness. This approach offers a chemical-free alternative to traditional insecticides and could be more cost-effective than current methods.

Scientists in Mexico tested four native strains of a fungus called Beauveria bassiana to see if they could control the Mexican fruit fly, which damages mango and orange crops. The fungal strains were highly effective, killing over 80% of the fruit flies in laboratory tests. The results suggest that using fungi naturally found in the region could be a more effective and environmentally friendly way to protect fruit crops compared to traditional pesticides.

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

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.

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

This study explores how to produce more fungal spores from Beauveria bassiana, a natural pest control organism, through a process called microcycle conidiation. Scientists found that a specific enzyme, chitin deacetylase, plays a crucial role in this process. They also discovered that coating these spores with nanoparticles made them more resistant to heat and UV light, making them more effective for field application against insect pests like leaf caterpillars. The nanocoated spores maintained their ability to kill pests while being more stable in harsh environmental conditions.

Effect of Rare, Locally Isolated Entomopathogenic Fungi on the Survival of Bactrocera oleae Pupae in Laboratory Soil Conditions

Researchers tested seventeen types of fungi that infect insects to see if they could control the olive fruit fly, a major pest in Greece that damages olive crops. Using fungi from local Greek soil samples, they exposed young olive fruit flies to different fungal treatments both in soil and without soil. Some fungi, particularly Aspergillus flavus and Aspergillus keveii, were highly effective at killing the flies and preventing them from reproducing normally. These results suggest that using these naturally occurring fungi could be a safer alternative to chemical pesticides for protecting olive groves.

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.

A mycovirus shaped insect-pathogenic and non-pathogenic phenotypes in a fungal biocontrol agent

mycolabadmin

Scientists discovered that a virus living inside a beneficial fungus is responsible for the fungus’s ability to kill insect pests. When they removed the virus, the fungus completely lost its ability to penetrate and infect insects through their skin, but could still cause infection if injected directly into the insect’s body. This finding suggests that the virus controls a key enzyme needed for the fungus to break through the insect’s protective outer layer, opening new possibilities for creating more effective biological pest control agents.

Chemical clues to infection: A pilot study on the differential secondary metabolite production during the life cycle of selected Cordyceps species

mycolabadmin

This study examined two types of parasitic fungi (Cordyceps javanica and Cordyceps blackwelliae) that infect insects, comparing how they kill their hosts and what chemical compounds they produce during infection. Researchers found that each species uses different toxic molecules to infect insects, with C. javanica being more deadly and producing diverse compounds called beauveriolides. By analyzing infected insect corpses, scientists provided the first direct evidence that these toxic compounds are actually made during real infections, not just in laboratory cultures.
