Cyrtobagus salvinia-an exotic beetle released into a 2,800-acre reservoir in Betul district (MP) has successfully eradicated an invasive weed species, Salvinia molesta, within 18 months.
- Salvinia molesta, known locally as Chinese Jhalaar, is a highly detrimental aquatic fern. It had engulfed the entire Sarani reservoir (Satpura dam) built on the Tawa river in the Betul district of Madhya Pradesh.
- Cyrtobagus salvinia, a Brazilian bioagent specifically targeting Salvinia molesta, was imported to India after thorough research and with the necessary governmental approvals.
- The Sarani reservoir project represents the scientists’ most extensive and successful experiment to date.
- The insect solely feeds on Salvinia molesta and dies naturally once the food source is exhausted, posing no threat to the environment.
