The areas of the host tissue exploited by individual sedentary nematodes overlap. For sedentary nematodes with one generation at a time (e.g. Heterodera rostocbiensis) and penetrating randomly into but not damaging the host tissue, the relation between the densities of subsequent generations Pi and Pf is given by: Pf = a (- ln q)-1 (1 - qPi) in which a = the rate of multiplication when Pi ---> 0 (maximum rate of multiplication), q = 1 - p, p = the proportion of the total area available to the nematode population, that is exploited for food at a density Pi = 1. As not all eggs hatch or die, a density bPi must be added to find the total density after multiplication has been completed (b = the proportion of the eggs that do not hatch or die during the experiment). Results of an experiment by den Ouden & Seinhorst (1965) are in accordance with this equation but in most experiments severe damage caused by the nematodes makes the relation between density and rate of multiplication more complicated.
