The biological management of water hyacinth (Eichhornia crassipes) through Neochetina spp. was studied in the Panchaganga River, Kolhapur, India, where extensive infestations threatened ecological balance and human activities. Five sites along the river were monitored for six months after the introduction of Neochetina weevils. Initial water hyacinth cover averaged 85%, declining to 51% post-intervention, reflecting a 40% reduction. Water quality parameters showed significant improvements, with dissolved oxygen levels increasing by 25% and a slight pH rise indicating favorable ecosystem conditions. Biodiversity evaluations indicated a rise in species diversity indices and the resurgence of native fish species. Statistical analysis confirmed a strong correlation (R² = 0.85) between weevil density and biomass reduction. Visual and spatial analyses supported these findings, showing reduced hyacinth density and improved river navigability. This research demonstrates Neochetina spp. as effective agents for sustainable water hyacinth management, emphasizing their role in restoring ecological health in impacted river systems.
