A model of plant-to-plant movement of aphids: A new approach

  • Edwin H. Bryant


  1. 1.

    A stochastic model was applied to the changes in the distribution of aphids on plants in a field determined by their plant-to-plant movements.

  2. 2.

    The expected numbers of aphids on plants were calculated for the 5 days of an experiment reported byShiyomi (1967) and compared with observed frequencies at these times.
