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.

Biocontrol efficacy of Pochonia chlamydosporia against root-knot nematode Meloidogyne javanica in eggplant and its impact on plant growth

mycolabadmin

This study shows that a beneficial fungus called Pochonia chlamydosporia can effectively control harmful root-knot nematodes that damage eggplant crops. When applied to soil, this fungus directly attacks nematode eggs and parasitizes the parasitic juveniles, while also boosting the plant’s natural defense systems. Not only does the fungus reduce nematode populations by over 55%, but it also helps eggplant plants grow better with increased height, weight, and chlorophyll content, providing a promising eco-friendly alternative to chemical pesticides.

Biocontrol of Root-Knot Nematodes via siRNA-Loaded Extracellular Vesicles From a Nematophagous Fungus Arthrobotrys oligospora

Scientists developed a new way to control harmful root-knot nematodes that damage crops by using natural containers called extracellular vesicles from a fungus. These vesicles carry small RNA molecules that silence genes essential for nematode survival and reproduction. When tested on tomato plants, this fungal-based treatment reduced nematode damage by about 60% while promoting healthier plant growth, offering an eco-friendly alternative to chemical pesticides.
