In 1982 Carter reported two mechanisms in the resistance of certain species of lindens (777/aspp.) to the linden aphid, Eucallipterus tiliae: simple pubescence and glandular prominences on the underside of the leaves. Field studies conducted from 1991-93 confirmed that aphids reach higher numbers on linden species with reduced pubescence (T. cordataand T. europea) than on a more pubescent species (T. platyphyllos). The rate of aphids parasitized by the introduced parasitoid Trioxys curvicaudus is also higher on the latter species.
