This species is a serious rice pest in the Palearctic region, where it is native (
Olmi and Villani 1975
). It causes dark brown feeding spots on the leaves (
Fig. 5
). It is very similar to
S. agropyronensis
but has denticles on the cuticle. Although
S. glyceriae
was reported in North America more than a century ago, it has not become a rice pest in North America. The Edith Patch Collection (currently housed in the Canadian National Collection, Ottawa) was examined to locate Patch’s specimens of
S. glyceriae
for comparison. Unfortunately, no Patch specimens were found in the collection (R. Foottit, personal communication). Whether
Sipha glyceriae
constitutes a species complex, or whether host races occur, is not known. Re-collection of North America
S. glyceriae
for comparison with the Italian rice pest would be important to determine if they are conspecific.
