The relation between initial (Pi) and final (Pf) population densities of M. incognita (on a log scale) on Dinsire. Solid line fitted to the equation of Pf = M*Pi/ (Pi + M/a) population dynamics (Teklu et al. 2014). Straight diagonal dashed line: population equilibrium line: Pf = Pi, (A) and the relationship of nematode initial inoculums and the number of galls per pepper root system (B).
