Scientific name: Aphis craccivora
Aphis craccivora prefers plants in the Fabaceae (beans, peas and groundnuts), but it is highly polyphagous and has been found on many plant species. It feeds on the young shoots, leaves, flowers and fruits, and is strongly ant attended. It is also a vector of several viruses including broad bean mosaic virus, cucumber mosaic virus and groundnut rosette virus. The cowpea aphid has a cosmopolitan distribution.
