Effects of an Infestation of Blackmargined Aphid on Carbohydrates in Mature ‘Stuart’ Pecan1

Year: 1982

Type: article

Abstract: Twenty-one days of foliar feeding in late spring by the blackmargined aphid [ Monellia caryella (Fitch)] on a mature ‘Stuart’ pecan tree [ Carya illinoensis (Wang.) K. Koch] reduced soluble sugars and starch in leaves to 82% and 79%, respectively, of the aphid-free control. Chlorophyll levels were unaffected. Sugars were reduced to 75% of the control in both 1- and 2-year-old branches. Starch in 1-year-old branches was reduced to 71%, but was unchanged in 2-year-old branches.
