The coconut nettle caterpillar (Setora nitens) significantly impacts agriculture, particularly in coconut cultivation. PRIMA Agro Tech has developed a biocontrol approach to manage this pest, utilising Cordyceps fumosorosea and Metarhizium robertsii. This strategy aims to control the caterpillar in an environmentally sustainable manner, reducing the need for chemical pesticides and preserving the health and productivity of coconut plants.
The coconut nettle caterpillar is identifiable by their green-yellow colouring and two clumps of hair on the head and tail. The adult form, a moth, is nocturnal and lays eggs on the underside of leaves. The larvae that hatch from these eggs are known for their destructive feeding habits, creating holes in coconut palms.
In severe infestations, coconut nettle caterpillars can consume almost all the leaf blade tissue, leaving only the veins and midribs. This level of damage affects the aesthetics and health of the coconut plants and can lead to significant yield losses and weakened plant structure.
PRIMA Agro Tech employs two specific biocontrol microorganisms to manage coconut nettle caterpillar infestations effectively:
Cordyceps fumosorosea isolate B3: This entomopathogenic fungus targets the coconut nettle caterpillar by attaching it to its exterior and penetrating its body. Inside the host, Cordyceps fumosorosea proliferates, disrupting vital functions and ultimately leading to the pest’s death. This isolate is particularly effective due to its adaptability to different environmental conditions and its efficacy in targeting various pest species.
Metarhizium robertsii strain 6EIKEN: As a natural insecticide, this fungus adheres to the caterpillar’s exoskeleton and penetrates it. It grows inside the caterpillar, consuming its internal nutrients and releasing toxins that weaken and kill the host. This strain effectively controls various life stages of the coconut nettle caterpillar, from larvae to adults.
By combining these biocontrol agents, PRIMA Agro Tech offers a comprehensive and sustainable solution to the coconut nettle caterpillar problem. This approach eliminates existing pests and creates an environment less conducive to future infestations, ensuring long-term protection and health for coconut crops.
