Euseius concordis (Chant, 1959)

Distribution. Manihot esculenta (cassava) ( Euphorbiaceae); (Yaninek et al. 1993).

Remarks. A species of South American origin, it was released in Zambia in 1987 to control the introduced neotropical cassava green mite Mononychellus tanajoa (Bondar) ( Prostigmata: Tetranychidae) (Yaninek et al. 1993). It, however, was not found in post­release monitoring and has apparently not become established.
