EFFECTS OF INFESTATIONS BY Tyrophagus putrescentiae [Schrank] [ACARI: ACARIDAE] ON BIOCHEMICAL COMPOSITION OF WHEAT GRAINS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 50
Abstract
Present study on effect of T. putrescentiae on chemical composition of wheat showed losses in total soluble sugars contents [1.98, 5.71 and 9.76 % in wheat grains after 30, 90 and 180 days of infestation), significant increase in Reducing sugars [24.10 to 27.65 mg/1g in 0 to 180 days of infestation), a marked decrease in non reducing sugars [from 43.06 mg/1g in the control to 40.45, 36.91 mg/1g and 32.95 mg/ g at 30, 90 and 180 days of infestation), decrease in starch content [from 444.18 to 367.35 mg/1g from 0 to 180 days) and protein content [initially decreased to 12.16 from 12.56 mg/1 g after 90 days, thereafter slight increase was recorded). Mite number was found to be negatively correlated with total soluble sugar [r= - 0.95), starch content [r= -0.98) whereas positively correlated with reducing sugars [r= 0.91).
