Abstract

The fundatrix morph of Longicaudus trirhodus (Walker) is described for the first time. The main difference from the apterous viviparous female is the absence of cornicles. Fundatrices as well as both apterous and alate viviparous female were collected on cultivated roses in May and early June, 1984 at Fredericton, NB.
