First record ofQuadrastichus mendeli, a parasitoid ofLeptocybe invasa, in South Africa [PDF]

open access: yesSouthern Forests: a Journal of Forest Science, 2017
Leptocybe invasa, the blue gum chalcid, is a well-known pest of Eucalyptus globally. Since it was first observed in the Mediterranean and Middle East in 2000, it has spread to other countries where Eucalyptus have been planted. Efforts to control it have included the release of a number of larval and pupal parasitoids.
