Abstract

SUN PEST (Eurygaster integriceps Puton (Coleoptera: Scutelleridae) is one of the most important pests of wheat and barley that feeds on grains. So, this pest lives in carbohydrate-rich environment and its survival depends on carbohydrase enzymes. a-Amylase plays an important role in the SUN PEST digestion. The aim of the current research was to study the effects of proteinaceous extracts of bean, rice and chickpea seeds on a-amylase activity. So, the proteinaceous extractions of the seeds were extracted using 0.1 M Sodium chloride. The extractions were tested on a-amylase activity at 0.125, 0.25, 0.5, 1 and 2 mg of proteins/ml in In vitro conditions. The results showed that the bean and chickpea extracts were effective on a-amylase activity and their effects were dose-dependent meaning that with increasing of the dose, inhibition of the enzyme increases. For example, at the lowest dose (0.125 mg of proteins/ml), the bean and chickpea extracts inhibited 5 and 20% of the amylase activity, respectively. While at the highest dose (2 mg of proteins/ml) the inhibitory effects was 30 and 40%, respectively. Rice seed extraction did not produce any significant effect on a-amylase activity. These data showed that the proteinaceous extractions of chickpea and bean have the good potential for inhibition of SUN PEST a-amylase.
