چکیده

the sunn pest is a serious pest of cereals causing severe damage to cereals especially of wheat. its life cycle has two different phases, one is growth and development phase and the other is diapause phase which takes place in adult stage. in this study the effects of juvenile hormone analogue pyriproxyfen, ecdysone analogue methoxyfenozide and mixture of pyriproxyfen and methoxyfenozide on diapause termination of

comparison of energy reserves in prediapause and diapausing adult sunn pest, eurygaster integriceps puton (hemiptera: scutelleridae)

in this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. to this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. the results showed that prediapause males and females had signifi...

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...

Role 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...

Biological Characterization of Beauveria bassiana (Clavicipitaceae:Hypocreales) from Overwintering Sites of Sunn Pest, Eurygaster integriceps (Scutelleridae: Heteroptera) in Iran

Sunn pest is one of the most important cereal pests that affect both grain yield and quality of cereal in Iran. One potential control strategy is to use entomopathogenic fungi such as Beauveria bassiana Vuillemin as mycoinsecticide to control this pest. Naturally infested Sunn pests in Kermanshah province were collected and brought to laboratory. 10 isolates were selected for further analysis i...

Effects of Serine Protease Inhibitors on Growth and Development and Digestive Serine Proteinases of the Sunn Pest, Eurygaster integriceps

In the current study the effects of serine proteinase inhibitors (TLCK, TPCK, SBTI, and a combination of SBTI and TPCK) with concentrations of 1% and 4% of dietary protein in artificial diets were tested against growth of the Sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), development, and its gut serine proteinase targets. Analysis of variance indicated that protease inhibi...
