Digestive Proteolytic Activity in the Sunn Pest, Eurygaster integriceps
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...
متن کاملEvaluating the resistance to sunn pest (Eurygaster integriceps Put) and its relationship with high-molecular-weight glutenin subunit in wheat
The crops are attacked by several species of bugs. Sunn pest, is the most important pest constitutes a major threat to wheat production and, to a lesser extent, barley production. Sunn pests are a complex of true bugs which belong to the genera Eurygaster (Scutelleridae), Aelia, Carpocoris and Dolycoris (Pentatomidae). Eurygaster integriceps is probably the most important species in Afghanistan...
متن کاملLife History Parameters of the Sunn Pest, Eurygaster integriceps, Held at Four Constant Temperatures
The Sunn-pest, Eurygaster integriceps Puton (Heteroptera: Scutelleridae), is the most important insect pest of wheat and barley in Iran. A demographic study was carried out in order to determine the effect of temperature on life history parameters of the pest. Life tables were constructed at four constant temperatures: 22, 25, 27, and 30 ± 1° C using Mahdavi wheat kernels as food. Finite and in...
متن کاملevaluation of resistance to sunn pest (eurygaster integriceps put.) in wheat and triticale genotypes
sunn pest (eurygaster integriceps put.) is one of the major pests of wheat in iran. identification of resistantcultivars is an effective integrated pest management (ipm) strategy. to identify the genetic response of wheat and triticale to sunn pest, and determine the relationship between resistance and morpho physiological traits, eight bread wheat breeding lines/cultivars, four durum wheat lin...
متن کاملRole of Symbiotic Bacteria in the Growth and Development of the Sunn Pest, Eurygaster integriceps
The Sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is the most important pest of wheat and barley in wide areas of the world. Different aspects of the insect's life history have been studied, but to date nothing is known about their microbial symbionts. Here, the contribution of symbiotic bacteria to the fitness of the bug was investigated by combining two different approac...
