(Krauss, 1848)[1]

Biomphalaria pfeifferi is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.

This snail is a medically important pest,[2] because of transferring the disease schistosomiasis.[3]

Distribution[]

Biomphalaria pfeifferi is an African species. It has recently expanded its native range.[2]

Distribution of Biomphalaria pfeifferi include:

The type locality is , Natal, South Africa[1] (in the times of the description it was the British Colony of Natal).

Ecology[]

Biomphalaria pfeifferi can survive up to 16 hours in anaerobic water using lactic acid fermentation.[6]

In Kenya, B. pfeifferi is positively associated with the common blue water-lily Nymphaea caerulea (the two species occur together).[3]

Parasites[]

Parasites of Biomphalaria pfeifferi include the following 11 species found in Tanzania:[7]

Control[]

In Kenya, releasing the edible American crayfish Procambarus clarkii as an introduced species has helped eliminate the mollusc, which it feeds on, as well as provided a new source of food and income,[3][9] but may also be impacting the environment by reducing the amount of native aquatic plants.[10]

The seeds of the tree Balanites aegyptiaca have a molluscicide effect on Biomphalaria pfeifferi.[11]

Substance Route LC50 Reference
Powder of crude kernels of Balanites aegyptiaca immersion(?) 60 ppm [11]
Acetone extract of powder of the kernels of Balanites aegyptiaca immersion(?) 172,40 ppm [11]
Ethanol extract of the powder of kernels of Balanites aegyptiaca immersion(?) 84,15 ppm [11]

Ethanolic extract of the fruits of Dalbergia sissoo (family Leguminosae) exhibited molluscicidal effect against eggs of Biomphalaria pfeifferi.[12]
