Cereal cyst Nematodes Heterodera spp. are pests of cereal crops, and their occurrence is known for many years both in Europe and in Norway. This group of nematodes forms a complex of species referred to as the "Heterodera avenae-complex", this includes H.avenae Wollenweber (CCN), H. bifenestra Cooper, H. mani Matthews, H. iri Matthews, H. hordecalis Andersson, H. latipons Franklin and H. filipjevi Krall. The host status of cereal cultivars differs between and within different species of the H. avenae-complex, and several pathotypes occur in several species. The border lines for species and pathotypes of the Heterodera avenae-complex are diffuse. Several pathotypes of CCN are found in Europe, and two pathotypes Ha51 and Ha11 are reported from Norway, Symptoms of damage by cyst nematodes in cereals are usually shown as patches of pale and stunted plants. The effects on the aerial parts of plants are identical with symptoms of severe nitrogen and other mineral deficiencies. Plants attacked by the nematodes wilt readily in dry weather. This reflects the nematode damage to the root system. In our experience most modern commercial varieties of cereals are equally susceptible to CCN. The aim of the project is to study the occurrence and distribution of the species within H. avenae-complex, to clarify the pathotype spectrum and to investigate the possible occurrence of microbial antagonists in Norway. The project is expected to be completed in 2001.
