Scientists have found a special fungus that naturally fights against the troublesome eucalyptus snout beetle, offering a green and cost-effective solution for protecting eucalyptus plantations.
The eucalyptus snout beetle, originally from Australia but now causing havoc globally, poses a significant risk to eucalyptus crops. These beetles harm trees by voraciously feeding on leaves, buds, and shoots, hindering growth and disrupting the plant’s ability to photosynthesize. Severe beetle infestations can strip entire forests of their leaves.
To tackle this issue sustainably, researchers turned to entomopathogenic fungi, natural enemies of pests. After studying infected beetles, they identified two types of fungi – Beauveria and Metarhizium – with strains capable of being effective biopesticides.
Choosing the Beauveria pseudobassiana strain for its strength and resilience, scientists created an optimized biopesticide called Bpbm Eco-Vida. In trials, this eco-friendly solution achieved 100% beetle mortality, with added benefits like a good shelf life and potential for mass production.
With over 20 million hectares of eucalyptus forests globally, finding sustainable ways to control their most destructive pest is crucial. Bpbm Eco-Vida, derived from nature’s own defense mechanisms, provides a long-lasting and environmentally friendly alternative to synthetic chemicals or costly interventions like introducing wasps.
Forest managers now have an affordable biological tool, combined with monitoring and cultural controls, to protect eucalyptus crops and ensure a sustainable future for essential forestry industries.
