Variability in the reproductive potential of Meloidogyne spp. is crucial to design suitable nematode management strategies. The reproductive potential of nine South African single-species Meloidogyne populations, M. enterolobii (5), M. incognita (2) and M. javanica (2), as well as three mixed-species communities (each containing two of the three species) were determined in glasshouse experiments. A mixed-species community of M. enterolobii and M. javanica had the highest reproductive potential (Rf = 15.7) in the initial experiment. For the repeat experiment, a single-species population of M. javanica was the most injurious (Rf = 19.1). Conversely, a single-species population of M. enterolobii had the lowest Rf values in the initial (Rf = 1.0) and repeat (Rf = 6.1) experiments. Substantial variation existed in terms of the reproductive potential of M. enterolobii single-species populations and mixed-species communities
