| Abstract/Contents: | No description had previously been available of the fundatrix of Sitobion avenae (F.) (Macrosiphum avenae), and, in work in the German Democratic Republic, this form was successfully reared on Poa annua, winter wheat, winter barley and winter rye in field cages. Its characters are compared with those of the apterous viviparous female. S. avenae shows a marked response to crowding by increasing the production of alates, which also form a high proportion of the population in autumn. In each of the four test years, the population completed its annual cycle by producing exclusively sexuales. |
