CARBOHYDRATES OF INNER BARK OFPINUS TAEDAAS AFFECTED BYDENDROCTONUS FRONTALISAND ASSOCIATED MICROORGANISMS

Abstract
Glucose, fructose, and sucrose were the only sugars detected in inner bark treated with a southern pine beetle–microorganism complex and two beetle-associated fungi. Treatments drastically lowered the reducing-sugar level. Storage of untreated bolts had no effect on reducing-sugar level; sucrose was lowered but not as much as in treated tissue. Starch content remained unchanged in all treatments.
