Hylesinus varius (Fabricius, 1775)

Distribution in Iran. Qom ( Borumand 1998 as Hylesinus fraxini Panzer 1799 ), generally distributed ( Modarres Awal 1997 as Hylesinus fraxini ), Iran (no locality cited) ( Mifsud & Knížek 2009; Knížek 2011). It is possible that some records of this species may actually refer to Hylesinus verae Petrov (see below).

General distribution. Europe, North Africa, Turkey. Records from Northern China ( Knížek 2011) may be misidentifications or indicate the introduction of the species to that region. Introduced into Brazil.

Taxonomy. The species has often been referred to in the literature as its synonym, Hylesinus fraxini (Panzer) (e.g. Stark 1952), or Leperisinus fraxini (e.g. Pfeffer 1995).

Biology. Usually the species breeds in trees of the family Oleaceae ( Fraxinus , Olea , Syringa ), but has also been recorded in other hosts ( Stark 1952). In Iran it has been recorded from Carpinus betulus , Corylus avellana (Betulaceae) , Robinia pseudoacacia (Fabaceae) , Fagus orientalis (Fagaceae) , Juglans regia (Juglandaceae) , Fraxinus excelsior , Olea europea , Syringa sp. ( Oleaceae ), Malus orientalis , Pyrus communis (Rosaceae) Acer sp. ( Sapindaceae ), ( Modarres Awal 1997). The biology and ecology of the species have been studied by Pedrosa- Macedo (1979), Lozano and Campos (1996), Løyning and Kirkendall (1999) and others.

Comments. Lozano et al. (1993, 1994) have studied the population dynamics, and Campos and Lozano (1994) two of its hymenopteran parasitoids for possible use in biological control.
