Discussion of research results

158 species are given in our material on fauna of 

wheat phytonematodes and its root soil. Discovered spe-

cies belong to 3 classes, 8 orders of phytonematodes and 

25 families. In the roots and rhizosphere soil of wheat the 

largest variety of different members of the family Aph-

elenchoididae (33 species), Cephalobidae (28 species). 

As the number of individuals in the root soil is domi-

nated by 15 species, mass species is 

P. rigidus. In the roots 

of the dominant species are absent, dominated by 10 spe-

cies. In the stems and leaves of phytonematodes relatively 

few in number.

According to the frequency of occurrence of these 

species can be distributed among the following groups: 

eudominants (6 species), dominants (9 species), sub-

dominants (14 species), recedents (30 species) and sub-

recedents (99 species).

It should be noted that the above mentioned para-

sitic nematodes were few and serious threat to wheat is 

not. However, to identify the wheat fields of the com-

plex is very pathogenic parasitic nematode species — 

Pratylenchoides crenicauda,  Helicotylenchus dihystera

Tylenchorhynchus brassicaeDitylenchus dipsaci and with 

a sufficiently high density of their populations, it is of 

particular concern, as the widespread danger of disease.
