Control Eichhornia crassipes, an invasive aquatic weed in South China with Neochetina eichhorniae

Control Eichhornia crassipes, an invasive aquatic weed in South China with Neochetina eichhorniae

Chinese Journal of Biological Control 17(3): 97-100

In August 1996, a total of 1000 adults of water hyacinth weevil (N eichhorniae) was released in a 1372-m2 area in a river totally covered by water hyacinth (E. crassipes) in Wenzhou, Zhejiang, China. Only 25% weed control was obtained two years after the release of N. eichhorniae, but 99% weed control was obtained one year later. As most of the plants died in the area of release, the weevils dispersed into the surrounding areas.
