GHAHARI et al.: Annotated catalogue of the Iranian Alydidae<br />

Subfamily Leptocorisinae Stål, 1872<br />

Genus Leptocorisa Latreille, 1829<br />

Leptocorisa oratoria (Fabricius, 1794)<br />

Material examined. ISFAHAN: Isfahan (1588 m), July 1999, 1 �, H. Masjedian leg., D. L. Carpintero det. New<br />

record for Iran.<br />

General distribution. China, Japan, Oriental and Australasian Regions (DOLLING 2006).<br />

Comment. Both the adults and nymphs feed on grains at the milking stage (especially wheat<br />

and barley). Feeding causes empty or small grains during the milking stage. At the soft or<br />

hard dough stage, feeding causes deformed or spotty grains. The grains become dark as a<br />

result of spilling of endosperm. The spillage becomes a medium for fungal infection. Since<br />

the eggs of Leptocorisa spp. are parasitized by Gryon spp. (Scelionidae) and Ooencyrtus<br />

spp. (Encyrtidae) (CORBETT 1930, AKBAR 1958, AHMAD 1965, REISSIG et al. 1986), and some<br />

specimens of Gryon sp. (near to G. nixoni Masner, 1965) and Ooencyrtus sp. were collected<br />

from Isfahan, they can probably be efficient parasitoids of L. oratoria in this region.<br />

Discussion<br />

The results of the present paper indicate that 21 species of 11 genera were identified from<br />

Iran so far. Iran is a large country incorporating various geographical regions and climates<br />

(Fig. 1), and we suppose that a large number of species remain to be discovered. To find<br />

new species and distributional records, more studies should be conducted on the Alydidae<br />

in all regions of Iran.<br />

Also, the host associations of Iranian alydids are poorly known. The majority of the alydine<br />

species in Iran are found on legumes. Riptortus linearis is a pest of legumes but it is also<br />

known from several unrelated host plants. The host associations of the Leptocorisinae are<br />

better known. SANDS (1977) provided a detailed account of the biology of the Leptocorisa<br />

species in Papua New Guinea outlining their life histories, host associations and crop damage.<br />

The works conducted on host plants of the world Alydidae are rather limited (SCHAEFER 1980).<br />

Determining of host plants and natural enemies (especially parasitoids) of alydids in Iran and<br />

also other regions of the world can be the important and invaluable research work.<br />
