R. Rakauskas, MORPHOMETRIC ANALYSIS OF EUROPEAN SPECIES OF THE GENUS APHIS (STERNORRHYNCHA, APHIDIDAE) INHABITING RIBES, European journal of entomology, 95(2), 1998, pp. 239-250
A review of the literary data on the life cycles and host plant relati
onships of Aphis grossulariae Kaltenbach, A. schneideri (Borner) and A

of characters commonly used in the keys. A modified key to fundatrices
, apterous and alate viviparous females, gynoparous and oviparous fema
les and males is presented.
