Beauveria bassiana for Coffee Berry Borer & White Stem Borer Control Naturally
Share
Insect pests are one of the major reasons for reduced coffee yield and poor bean quality. Pests such as coffee berry borer, white stem borer, mealybugs, aphids, whiteflies, and thrips damage leaves, stems, branches, and berries, leading to lower production and poor market value.
Beauveria bassiana is a beneficial entomopathogenic fungus that naturally infects and kills insect pests. It is widely used in Integrated Pest Management (IPM) and organic coffee farming because it provides effective pest control without leaving harmful chemical residues.
Regular application helps coffee growers reduce pest populations, protect developing berries, and improve coffee quality.
What is Beauveria bassiana?
Beauveria bassiana is a naturally occurring beneficial fungus that attacks insects. After coming in contact with the insect body, fungal spores germinate, penetrate the insect cuticle, multiply inside the insect, and eventually kill the pest.
It is safe for the environment and an excellent alternative to repeated chemical insecticide applications.

How Beauveria bassiana Works
Spore Attachment
Spores stick to the insect body after spraying.
Germination
Spores germinate under suitable humidity and penetrate the insect cuticle.
Internal Infection
The fungus grows inside the insect and consumes internal tissues.
Insect Death
The insect stops feeding and eventually dies.
Natural Spread
New spores develop on infected insects, helping reduce pest populations naturally.
Application Methods
Foliar Spray
Spray leaves, stems, branches, and berries thoroughly where insect activity is observed.
Preventive Application
Apply before heavy pest infestation for better biological control.
Curative Application
Spray immediately after the first signs of pest activity.
