ABSTRACT
The interactions of the cyst nematodes Heterodera daverti, H. goldeni and H. zeae with the root-knot nematode
Meloidogyne incognita on rice (Oryza sativa) cultivars 'Giza 178' and Sakha 101' were studied in the greenhouse.
Inoculation with H. goldeni alone or one week before inoculation with M. incognita on rice cv. Sakha 101
resulted in a significant increase in the number of cysts of H. goldeni as compared to plants inoculated with M.
incognita concurrently or a week beforehand. When H. daverti or H. zeae were inoculated one week after
inoculation with M. incognita on rice cultivars Giza 178 or Sakha 101, respectively, the final population of these
cyst nematodes increased. Treatments with M. incognita alone or one week before inoculations with the tested
cyst nematodes induced a significant
