摘要：

A new version of Vanderplank's epidemic model corrected for removals is presented. Incorporation of host growth and variable latent period allow a more realistic modelling of epidemic development while preserving the simplicity and biological meaningfulness of the original model. Host growth is driven through degree-day accumulation. The length of the latent period varies with temperature according to a beta function. Calculations are made through numerical integration combined with boxcar trains. The model has been implemented in a program called "Epiphyt" which runs on personal computers. Typical output produced by the program is shown.
