SEXUAL FORMS OF TOXOPTERA GRAMINUM, ROND.

Generation of clonal diversity by sexual reproduction in the greenbug, Schizaphis graminum.

In the United States, the greenbug, Schizaphis graminum (Rondani), reproduces primarily by apomictic parthenogenesis. Although a periodic sexual cycle exists, the extent to which it occurs naturally and its influence on the genetic variability of greenbug populations is unclear. Length variation in the intergenic spacer (IGS) of the rRNA cistron in the greenbug indicates that populations are ma...
