sunn pest is one of the most important cereal pests that affect both grain yield and quality of cerealin iran. one potential control strategy is to use entomopathogenic fungi such as beauveriabassiana vuillemin as mycoinsecticide to control this pest. naturally infested sunn pests inkermanshah province were collected and brought to laboratory. 10 isolates were selected forfurther analysis in th...

eurygaster integriceps Puton, commonly known as sunn pest, is a major pest of wheat in Northern Africa, the Middle East and Eastern Europe. This insect injects a prolyl endoprotease into the wheat, destroying the gluten. The purpose of this study was to clone the full length cDNA of the sunn pest prolyl endoprotease (spPEP) for expression in E. coli and to compare the amino acid sequence of the...

chemical control against overwintered adults of sunn pest eurygaster integriceps put. mostly has low efficacy. today using insecticides and formulations that have durable toxicity on overwintered adults is more approved, because this strategy can reduce treated area against new generation. this research was conducted with six treatments and four replications in randomized complete block design ...

trissolcus grandis thomson is a solitary egg parasitoid of sunn pest, eurygaster integriceps puton. although widely distributed, it has often been overlooked in field surveys. our objectives were to develop an efficient rearing technique for t. grandis, and to determine the basic bionomics and demographic parameters, necessary for future augmentative biological control programs. exposure of 0-4...

a study of insect digestive enzymes makes sense given that the gut is the major interface between the insect and its environment. an understanding of gut and digestive enzyme function is essential when advanced methods of insect management such as application of enzyme inhibitors and transgenic plants are developed to control insect pests. the aim of the current research project was to study mi...

The Sunn pest, Eurygaster integriceps Puton (Heteroptera: Scutelleridae), is one of the most important pests of wheat and causes considerable damage to this valuable crop annually. Digestive proteinase activity of adult insects was investigated using general and specific substrates and inhibitors. Proteolytic activity was low when the common conventional substrates, azoalbumin, azocasein and he...

sunn pest (eurygaster integriceps put.) cause serious economic damage to wheat and barley in borujerd, north of lorestan province, iran. sweep net sampling, is the most convenient sampling procedure for many arthropods, but it is difficult to interpret in terms of accuracy and precision. much of the variation of sweep net catches, stems from human factors and its calibration. in this research, ...
