Relationship Between Aphid Infestation and Chlorophyll Content in Fabaceae SpeciesDOI: 10.2478/v10182-010-0026-4 Keywords: chlorophyll a+b, Fabaceae, Acyrthosiphon pisum, SPAD values Abstract: We determined the chlorophyll a and b levels (SPAD readings) in uninfested leaves and in leaves after 7 and 17 days of aphid infestation in four Fabaceae species (Pisum sativum L., Vicia faba L., Trifolium pretense L, Medicago sativa L.). Feeding by pea aphids Acyrthosiphon pisum Harris (Hemiptera: Aphididae) caused significant loss of chlorophyll a and b in the infested plants. Uninfested leaves on both short- and long-infestation plants had significantly higher chlorophyll a and b than infested leaves.
