| 520 | _aViviparae of Sitobion avenae in clip-cages on winter wheat in field plots insouthern England were monitored throughout the 1980-81 winter to determine characteristics of development, reproduction and lifespan under winter conditions. Rate-temperature relationships for development and reproduction werewell described by straight lines when temperatures were measured above 3øC. A simple thermal-time scale could therefore be used for both processes. The parental morph and the time of year modified thermal-time requirements for the production of an adult's first 20 nymphs but did not affect those for development. For both alatae and apterae, nymph production per | ||
