An exotic beetle released into a vast (2,800-acre) reservoir in Betul district has successfully eradicated an invasive weed species, Salvinia molesta, within 18 months.

Salvinia molesta, a highly detrimental aquatic fern, had engulfed the entire Sarani reservoir (Satpura dam) built on the Tawa River in the Betul district of Madhya Pradesh. Known locally as “Chinese Jhalaar”, this invasive species was first spotted in 2018 and had completely carpeted the reservoir by 2019.

Scientists revealed that Cyrtobagus salvinia, a Brazilian bioagent specifically targeting Salvinia molesta, was imported to India after thorough research and with the necessary governmental approvals.
