Detection of grain infestation caused by the granary weevil (Sitophilus granarius L.) using zymography for α-amylase activity

Granary weevil infestation in wheat kernels is difficult to detect since the insects cause a hidden infestation by developing inside the grain. In order to identify an early infestation of stored wheat, a technique involving electrophoresis combined with zymographic assay of α-amylases has been deve...
