Feeding losses and biochemical changes caused by Sitophilus oryzae L. infestation in maize varieties

Abstract
Food grain during storage undergoes considerable loss due to infestation
by stored grain weevils. The most common among them prevalent in Bihar is Sitophilus
oryzae. It penetrates holes in the maize and feeds upon reducing it into
dusting material not only that excreta and remains of dead and decaying insects
causing fowling of the food. So the food undergoes both quantitative and
qualitative changes. To ascertain the losses seven replicate experiments are
run with a control and the samples are weighed before and after infestation.
Similarly, the loss of individual amino acids has been ascertained by carrying
out paper chromatography. Different rice varieties subjected to infestation
underwent different degrees of losses while in Rattan the weight loss was most
pronounced (21.26%), the shaktiman1 suffered the least (0.67), Ganga 10
underwent moderate losses (14.01%). As far as loss of amino acid is concerned
pre infestation Shaktiman1 had 12 amino acid and after post-infestation loss 2
amino acid of which both are non essential. Ganga 10 had 11 amino acid before
infestation but after infestation it losses four amino acid out of which three
is essential. Before infestation Rattan had 14 amino acid but after infestation
it losses six amino acid out of which three is essential.
