Plant Parasitism and Resistance

Iowana frisoni Hottes was collected and studied for the first time since its original collection in 1925. It was found in remnant prairies where it fed on the basal stem of the endemic plants Silphium laciniatum L. and S.terebinthinaceum Jacquin (Asteraceae). Later in the season it fed on the stem or leaf stipules within the cavity created by the leaf axil. The aphid was always tended by ants, Lasius flavus (E), L. neoniger Emery, and two Crematogaster species, which housed the aphids by building soil collars around the bases of plants and sealing leaf axils with soil and dead plant material. The ants also carried I. frisoni underground when the aphid colony was disturbed. We redescribe the apterous vivipara morph of I. frisoni and describe for the first time the fundatrix, alate vivipara, male, ovipara, and egg.
