| The Kenya Agricultural Research Institute (KARI) imported 12 800 curculionid weevils (Neochetina spp.) from Benin, Uganda, South Africa and Australia for biological control of water hyacinth between 1993 and1998. In 1996, KARI’s rearing and quarantine facility at the National Agricultural Research Centre, Muguga, provided initial “breeding stock” to another rearing facility at the National Fibre Research Centre, Kibos, near Lake Victoria. To date, 36 500 weevils and 42 000 weevil eggs have been produced from Kibos. About 2000 weevils were produced each month from plants grown in plastic basins, galvanized corrugated iron sheet tanks and a polypropylene rearing pool. Between January 1997 and August 1998, KARI released 36 250 Neochetina weevils at 27 sites... |

| The Kenya Agricultural Research Institute imported 12,300 curculionid weevils (Neochetina spp.) from diverse sources, for biological control of water hyacinth in Lake Victoria, as part of the World Bank-funded Lake Victoria Environmental Management Project in East Africa. In addition to the rearing and quarantine facility at Muguga, a second rearing facility was established in 1996 at Kibos, near Lake Victoria. The Kibos rearing facility and two community rearing facilities at the lakeshores, have produced approximately 100,000 adult weevils and 42,000 weevil eggs over a three-year period. Since January 1997, some 73,500 Neochetina weevils have been released at 29 sites and an additional 10,000 redistributed at several sites. Visual observations and... |
