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 کاملEffects 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...
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...
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 کاملDigestive proteolytic activity of Scrobipalpa ocellatella (Lepidoptera: Gelechiidae) on various sugar beet cultivars
فعالیت پروتئولیتیک گوارشی بید چغندرقند، Scrobipalpa ocellatella (Boyd)، روی ارقام مختلف چغندرقند(Rosire, Laetitia, Ardabili, Persia, Aras and Flores) تحت شرایط مزرعه‌ای بررسی شد. لاروهای سن سوم روی رقم Flores بیشترین فعالیت آنزیمی و لاروهای پرورش‌یافته روی رقم Aras کمترین فعالیت آنزیمی را داشتند. آنالیز زایموگرام نشان داد که کمترین تعداد آیزوزایم‌های پروتئاز در عصاره معده میانی لاروهایی بود که ...
