Abstract

Temperature is the most important climatic factor determining the geographical distribution of many species of root-knot nematodes (Meloidogyne spp.). Survival of the eggs of Meloidogyne may be reduced in cold <5°C), or warm soils (>35°C) (Taylor and Sasser, 1978). As part of a study of the biology of M. ardenensis Santos, a root-knot nematode found in Scotland, the effect of temperature on egg viability and hatching was studied. For comparison eggs of M. hapla Chitwood, a species also found in temperate regions, and of M. incognita (Kofoid et White) Chitw., and M. javanica (Treub) Chitw., two species from warmer parts of the world, were tested. Daulton and Nusbaum (1961) observed that the optimum temperature for egg-hatch of M. javanica varied for different populations, and therefore I used several populations of each species in the experiments.
