Getachew Beneberu1 and Wassie Anteneh2

Water hyacinth (Eichhornia crassipes) is a major problem in many parts of the globe causing various threats. In this study an attempt was made to assess the potential of neochetina spp. introduced from Lake Victoria (Uganda), to control water hyacinth infestation A lath-house of 10m by10m dimension was constructed near the shores of Lake Tana. Eight pairs of weevils were placed in tubs with several water hyacinth plants. The weevils allowed to feed and mate for 5-6 days and finally retrieved and inoculated into newly prepared tubs. Host specificity test was carried out among common plants in the Lake Tana areas.
