Leptocorisa oratoria (Fabricius, 1794)

Material examined. ISFAHAN: Isfahan (1588 m), July 1999, 1 J, H. Masjedian leg., D. L. Carpintero det. New record for Iran.

General distribution. China, Japan, Oriental and Australasian Regions ( DOLLING 2006).

Comment. Both the adults and nymphs feed on grains at the milking stage (especially wheat and barley). Feeding causes empty or small grains during the milking stage. At the soft or hard dough stage, feeding causes deformed or spotty grains. The grains become dark as a result of spilling of endosperm. The spillage becomes a medium for fungal infection. Since the eggs of Leptocorisa spp. are parasitized by Gryon spp. (Scelionidae) and Ooencyrtus spp. (Encyrtidae) ( CORBETT 1930, AKBAR 1958, AHMAD 1965, REISSIG et al. 1986), and some specimens of Gryon sp. (near to G. nixoni Masner, 1965 ) and Ooencyrtus sp. were collected from Isfahan, they can probably be efficient parasitoids of L. oratoria in this region.
