Three experiments were conducted to evaluate the reproduction and damage potential of Meloidogyne konaensis on resistant and susceptible rootstocks of coffee in four soils under two moisture regimes representative of areas where coffee is grown in Hawaii. Reproduction of M. konaensis occurred readily in all soil types, but lowest in the Hydric Dystrandept soil where the holotype was first founded. Root galling, however, was greatest in this soil. M. konaensis suppressed growth of coffee in all four soils. Greater galling occurred under constant moisture (33kPa) than under fluctuating moisture (33-1500 kPa). Fifty percent more eggs were produced at constant moisture than under fluctuating moisture conditions. Development of M. konaensis was completed in C. arabica, as expected for a good host. Coffea liberica var. dewevrei was resistant to M. konaensis and C. arabica was susceptible. C. liberica var. dewevrei allowed development of only a few adult females and males.
