[Occurrence of Lysiphlebus testaceipes (Cresson) (Hymenoptera: Aphidiidae) on aphids (Hemiptera: Aphididae) in wheat plantation in Medianeira, Parana State, Brazil].

This paper records the occurrence of Lysiphlebus testaceipes (Cresson) attacking aphids in wheat plantation in Medianeira, in the west region of Paraná State, Brazil. This microhymenoptera was introduced and released by Embrapa Trigo, from 1978 to 1992 in the wheat production region at the state of Rio Grande do Sul, what suggests that individuals of this species may show high dispersal ability.
