Akanthomyces

Akanthomyces is a genus of entomopathogenic fungi renowned for their ability to parasitize and kill various species of insects and mites. Unlike traditional plant diseases, this fungus is utilized in agronomy as a beneficial agent to manage pest populations naturally without harming the crops themselves.

The infection process begins when fungal spores adhere to the insect's cuticle. After germination, the fungal mycelium penetrates the host's body and colonizes its internal tissues, depriving the host of nutrients and releasing secondary metabolites that lead to the insect's death within a few days.

This fungus primarily targets sap-sucking pests, such as aphids, whiteflies, and spider mites. Due to its high specificity and safety for non-target organisms, it is increasingly favored as an active ingredient in biological insecticides used in both greenhouse and open-field vegetable production.

Environmental conditions, particularly temperature and humidity, play a decisive role in the efficacy of Akanthomyces. High relative humidity is essential for the germination and spread of fungal spores across the foliage, whereas prolonged drought significantly hinders the biological control potential.

Integrated pest management strategies often incorporate these fungi to reduce reliance on chemical pesticides. To maintain high levels of biocontrol, growers should avoid applying synthetic broad-spectrum fungicides that could inhibit the development of the fungus, ensuring a healthy balance within the agro-ecosystem.
