Summary

  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. 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.

A portion of this study was carried out while the author was a National Science Foundation pre-doctoral fellow in the Department of Entomology, The University of Kansas. The manuscript was completed during the tenure of a National Science Foundation post-doctoral fellowship (No. 48046) at The University of Chicago.
