Summary Shiyomi (1967a and b) proposed two models which describe the reproduction and the plant‐to‐plant movement of aphids. For the explanation of the whole process of development of population of aphids, the above two models were incorporated into a new model (called Model C). This model is superior in the following points to the negative binomial model: Model C has 7 parameters and gives a fuller explanation compared with the negative binomial model which has 2 parameters. Model C describes the structure of population at any stage of its development, while the negative binomial model describes that of a well developed stage of population.
