Tea plantations are continuously exposed to insect pests that damage young shoots, leaves, and tender buds. Pests such as tea mosquito bug, aphids, mealybugs, whiteflies, caterpillars, loopers, and beetles reduce tea quality, lower yield, and weaken tea bushes.

Frequent use of chemical insecticides often leads to pest resistance, harmful pesticide residues, destruction of beneficial insects, and increased production costs. For sustainable tea cultivation, farmers are increasingly adopting Beauveria bassiana, a highly effective biological insecticide that naturally controls insect pests without harming the environment.

Beauveria bassiana is an entomopathogenic fungus that infects and kills insect pests naturally. Once applied, it spreads through the pest population, providing long-lasting biological control while preserving beneficial organisms and improving the ecological balance of tea plantations.

What is Beauveria bassiana?

Beauveria bassiana is a naturally occurring beneficial fungus used as a biological insecticide. Unlike chemical pesticides that kill insects immediately, Beauveria infects insects through their outer body covering (cuticle), grows inside the insect, and eventually causes its death.

This natural process provides effective pest control while reducing the need for repeated chemical sprays.

Why Tea Farmers Should Use Beauveria bassiana

Tea is harvested frequently, making pesticide residue management extremely important. Beauveria bassiana offers a residue-free and environmentally friendly alternative.

Major Tea Pests Controlled by Beauveria bassiana

Beauveria bassiana is effective against a wide range of economically important tea pests.

It helps manage:

• Tea mosquito bug
• Aphids
• Mealybugs
• Whiteflies
• Thrips
• Caterpillars
• Loopers
• Leaf-eating beetles
• Leaf-feeding larvae
• Soft-bodied insect pests

How Beauveria bassiana Works

Beauveria controls insects through a unique biological infection process.

Spore Attachment

Spores attach to the insect's body after spraying.

Germination

Under suitable humidity, spores germinate and penetrate the insect cuticle.

Internal Infection

The fungus grows inside the insect and feeds on its internal tissues.

Pest Death

The infected insect gradually stops feeding, becomes inactive, and dies naturally.

Spread to Other Insects

Under favorable environmental conditions, new spores develop on infected insects and spread to nearby susceptible pests.

Application Methods

Foliar Spray

Spray uniformly on both upper and lower leaf surfaces where insects are active.

Nursery Spray

Protect young tea plants from early insect infestations.

Preventive Spray

Apply before pest populations become severe for maximum effectiveness.
