“…Among sunn pests, the species of the genera Eurygaster and Aelia (Heteroptera: Pentatomidae) are the most prominent on wheat in Europe (Ruiz et al 2001; Vaccino et al 2006), Asia (Kinaci et al 1998) and northern Africa (Vidal 1949; Parker et al 2001). In particular, the most noxious pests are E. integriceps in south-eastern Europe and Asia (Critchley 1998), and Eurygaster maura (L.) and Eurygaster austriaca (Schrank) in western Europe (Ruiz et al 2001; Vaccino et al 2006).…”

1 Consiglio per la ricerca in agricoltura e l'analisi dell 'economia agraria (CREA) SUMMARYSeveral species of Heteroptera are responsible for kernel damage in wheat [Triticum aestivum (Poaceae)], which affects bread-making quality. In Europe, the most noxious bugs belong to the genera Eurygaster (Scutelleridae) and Aelia (Pentatomidae). In the present work, five bug species frequently found in wheat fields in north-western Italy, Eurygaster maura, E. austriaca, Aelia acuminata, Nezara viridula and Carpocoris purpureipennis, were tested in field trials for their capacity to induce wheat damage. The sodium dodecyl sulphate sedimentation volume test (SSV) was used as the qualitative control. Among the bug species tested, E. maura was the most noxious pest, with C. purpureipennis being almost as noxious as E. maura. In contrast, E. austriaca and A. acuminata, which have been considered the wheat pests of major importance, as well as N. viridula, caused no or only moderate damage to wheat quality. The adoption of an antiserum specifically produced with E. maura salivary glands proved to be effective and specific in detecting bug damage. Therefore, this polyclonal antibody is promising for the development of a reliable test for the quick evaluation of commercial wheat flour batches.

“…The typical sign of infestation is the presence of a black central pinpoint on the grain surrounded by a pale or discolored halo produced by the pest's feeding, piercing and cutting of tissues while injecting digestive enzymes, proteases and amylases through the salivary canal to liquefy food into a nutrient-rich slurry (Critchley 1998;Hariri et al 2000). The salivary proteinase enzymes injected into the seed cause destruction of gluten and reduce the doughbaking quality (Kinaci et al 1998;Köksel et al 2002;Kinaci and Kinaci 2004). Because of the proteolytic enzyme content, damaged wheat flour used for breadmaking produces a runny and sticky dough leading to a low bread volume and an unacceptable texture (Kinaci and Kinaci 2007;Ravan et al 2009).…”

The effects of Cephalaria syriaca flour on the quality of sunn pest-damaged wheat were investigated. Sunn pest-damaged wheat was blended into sound wheat at different levels (5, 10 and 15%). C. syriaca flour was then added at 0.5, 1.0 and 1.5% levels. The rheological properties of sunn pest-damaged wheat flour with added C. syriaca flour were considerably improved, in particular with regard to farinograph characteristics (dough stability, mixing tolerance index [MTI] and degree of softening [DS]) and instrumental textural properties (area and maximum resistance) compared to control. The dough stability value increased significantly (P < 0.01) as C. syriaca flour level increased for all sunn pest-damaged wheat levels. The addition of sunn pest-damaged wheat at 15% level greatly increased the MTI and DS values of dough (202.5 and 282.5 BU); however, the addition of 1.5% C. syriaca to this blend significantly decreased these values (87 and 94.5 BU; P < 0.01). PRACTICAL APPLICATIONSA large number of optional ingredients are included in bread formulation to improve its bread-making quality. Cephalaria syriaca is traditionally used to improve the rheological properties of dough by farmers living in some part of Turkey. The addition of C. syriaca flour to sunn pest-damaged wheat significantly affected the physical, technological and rheological properties of the sunn pestdamaged wheat flour and dough and improved the bread-making quality. Thus, the deteriorated dough-kneading properties induced by sunn pest-damaged wheat can be slightly improved by C. syriaca flour supplementation.

“…Infection of growing wheat and barley crops with insects of the genus Eurygaster Lap. (Sunn bug) leads to substantial losses of crop yield and quality in many countries including parts of Eastern and Southern Europe, West and Central Asia, and North Africa. − More than 10 million Ha of wheat, nearly half of which lies in the Near East, is attacked by the Sunn bug . Losses from Sunn bug infestation result both from seedling loss and failed germination of damaged seed.…”

Glutenin hydrolyzing proteinases (GHPs) have been purified, by affinity chromatography, from wheat seeds damaged by the Sunn bug Eurygaster integriceps (Hemiptera, Scutelleridae). A 28 kDa protein was partially sequenced by mass spectrometry and Edman degradation which showed homology to serine proteases from various insects. Three full length clones were obtained from cDNA isolated from Sunn bug salivary glands using degenerate PCR based on the sequences obtained. The cleavage site of the protease was determined using recombinant and synthetic peptides and shown to be between the consensus hexapeptide and nonapeptide repeat motifs present in the high molecular weight subunits of wheat glutenin (PGQGQQ∧GYYPTSLQQ). Homology models were generated for the three proteinases identified in this study using the high resolution X-ray structure of a crayfish (Pontastacus leptodactylus) trypsin complexed with a peptide inhibitor as template (PDB accession 2F91). The novel specificity of this protease may find applications in both fundamental and applied studies.
