Temporary small-scale colonization of the Beffa form of the Simulium damnosum theobald complex (Diptera: Simuliidae) in Africa.

Two populations of the Beffa form of Simulium damnosum s.l. were colonized on a small scale for the first time in Africa. The colonies survived for three and five generations, respectively. Information gained led to improvements in adult handling techniques which proved adequate for colony maintenance despite the small numbers reared. Nevertheless, large scale rearings are required to avoid inbreeding and to produce sufficient numbers for experimental purposes.
