Thrips, specifically the Heliothrips species, are small but significant pests in agriculture, known for attacking a variety of plants and causing substantial damage. PRIMA Agro Tech approaches this challenge with biocontrol microorganisms like Metarhizium anisopliale and Beauveria bassiana, targeting and mitigating thrips infestations. This strategy provides a sustainable and effective solution for protecting crops from the extensive damage caused by thrips.
Thrips are small pests, typically yellow-brown or black, measuring about 1 mm. They live in groups and are commonly found on shoots and the undersides of leaves, sipping fluids from plants and spreading viruses.
The initial symptoms of its attack include young leaves becoming wrinkled or curled and fruits becoming malformed. Infestations can stunt plant growth, halt productivity, and lead to plant death if a virus attacks.
Thrips feed primarily on ornamental plant foliage, first attacking the lower surface and then moving to the upper surface as the population increases. The leaves become discoloured and distorted between the lateral veins, turning yellow and dropping in severe cases. Thrips also leave small droplets of black excrement on the leaves.
PRIMA Agro Tech employs specific biocontrol microorganisms to effectively manage thrips infestations, focusing on their unique mechanisms of action:
Metarhizium anisopliale isolate D1: This entomopathogenic fungus combats thrips by adhering to its exoskeleton. Once attached, it germinates and penetrates the insect’s body, spreading internally. Metarhizium anisopliale disrupts the thrips’ vital functions by producing toxins and enzymes that deteriorate the internal organs, ultimately leading to the pest’s death. This fungus is particularly effective due to its ability to target a broad range of insect pests and its persistence in the soil, providing long-term protection.
Beauveria bassiana isolate B33: Acting as a natural insecticide, Beauveria bassiana works by attaching to the thrips’ cuticle. The fungus then breaches the exoskeleton and grows inside the insect’s body. As it proliferates, Beauveria bassiana consumes the thrips’ nutrients and releases toxins, causing the insect to weaken and die. This isolate is especially useful for its virulent properties and capability to control various stages of thrips, from larvae to adults.
With their specific and potent mechanisms, these biocontrol agents offer a comprehensive approach to reducing thrips populations. They target and eliminate existing thrips and create an environment less conducive to their reproduction, ensuring sustainable protection for crops against these pests.
