Abstract:
The insect species on Eichhornia crassipes (water hyacinth) on Ogun River, South Western, Nigeria were surveyed with the objective of determining if any of them could serve as a bio-control agent of water hyacinth. They were collected by means of using insect sweep net, on monthly basis for 18 months. The insect species collected included Zonocerus varieqatus L; Attractomorpha aurivilla, Oxya hyla Serville, Lamprococa occidentalis, Leptauleca fissicollis, Lagria villosa Fab:, Locris maculata, Aspavia armigera, Acisoma panorpoides and Musca domestica. Adult insect species performed different kinds of activities on the water hyacinth (E. crassipes) such as feeding, resting, mating and tunneling into the petiole of water hyacinth. However, all these activities of the insects had no visible damaging effects on the growth and proliferation of water hyacinth on Ogun River, hence they could not be used as bio-control agents for water hyacinth.
