تأثير صور من مساحيق بذور البزاليا و الفاصوليا في بعض المتغيرات الكيموحيوية لخنفساء الخابرا Trogoderma granarium

Abstract EN

The present study was conducted to determine the effect of pea Pisum sativum L.

and bean Phaseolus vulgaris L.

powders formulations starch, crude, high-protein, pure protein in some biochemical parameters of khapra beetle, Trogoderma granarium reared on wheat grains treated and untreated with the powders.

The results showed that mixing wheat grains with pea and bean powders then rearing larvae of khapra beetle on it affects clearly on the proteins and carbohydrates concentration in the larval extraction, the powders caused reduction in their concentration.

The lowest percentage of proteins and carbohydrates was found in the larval extraction for the larvae reared on the wheat grains treated with pure protein powder of pea and bean, 6.37 and 8.00 % for protein and 0.50, 1.06 % for carbohydrates respectively, in comparison with control that gave 25.56% for proteins and 4.70 % for carbohydrate.

So that powder causes an activity inhibition of α- amylase and protease enzymes.

The pure protein powder of pea and bean showed a superior value of inhibition percentage ; 64 and 51 % for α- amylase enzyme and 95, 76 % for protease enzyme, respectively.
