Results of the research

In the study period, on wheat and its rhizosphere soil 

we found 158 species of plant-parasitic nematodes be-

longing to 3 subclasses, 8 orders and 25 families.

In our material Adenophorea subclass represented by 

3 orders: Enoplida, Mononchida, Dorylaimida. Enoplida 

order contains only one family with two rarely occurring 

species: 



Trishistoma monohystera, Tobrilus kirjanova. In the 

order of Mononchida there are two families contained one 

type of each. Dorylaimida order represented 6 families: 

Dorylaimidae, Qudsianematidae, Discolaimidae, Apor-

celaimidae, Xiphinematidae, Leptonchidae, among which 

the most diverse in species composition is Qudsianema-

tidae (4 species), Aporcelaimidae (4), Dorylaimidae (4). 

The rest of the families contain 1–2 species.

Chromadoria subclass presented 2 orders: Monhys-

terida, Plectida. Monhysterida order represented by one 

family Monhysteridae, and the other order family Plecti-

dae. Monhysteridae family includes freshwater species: 



Monhystera simplex, Geomonhystera villosa. The family 

Plectidae is represented by four rarely occurring species.

Rhabditia subclass includes Rhabditida, Aphelenchi-

da, Tylenchida orders. Rhabditida order includes 3 fami-

lies: Cephalobidae, Panagrolaimidae, Rhabditidae. Among 

the above families of the greatest species diversity ob-

served in the family Cephalobidae (28 species), the family 

Panagrolaimidae contains 14, Rhabditidae — 10 species.

Aphelenchida order represented by 4  fami-

lies: Aphelenchidae, Paraphelenchidae, Aphelen-

choididae, Seinuridae and 40  species, 33 of which 

belong to the family Aphelenchoididae, 5 — to Aphelen-

chidae, one by one — Paraphelenchidae and Seinuridae.

Tylenchida order includes 40 species belonging to 

7 families: Tylenchidae (10 species), Dolichodoridae 

(4), Psilenchidae (2), Hoplolaimidae (3), Pratylenchi-

dae (4), Neotylenchidae (5), Anguinae (12).

On a variety of species and number of individuals 

among the orders allocated Rhabditida, containing more 

than 32% of all detected species and 61% of individu-

als of phytonematodes. Aphelenchida and Tylenchida 

orders comprise 25.3% of the species, 22.6% and 14.3% 

of individuals nematodes. All other orders in the fauna of 

wheat presented rarely occurring and few species.

In the root soil of wheat dominated types (in de-

scending order): 

Panagrolaimus rigidus (popular type), P. 

subelongatus, Chiloplacus sclerovaginatus, Aphelenchoides 

parietinus, A.composticola, Rhabditis brevispina, Ditylenchus 

dipsaci, Acrobeloides nanus, A.buetshlii, Cepholobus persegnis, 

Pratylenchus pratensis, Bitylenchus dubius, Tylenchorhynchus 

brassicae, (total 13 species). The roots of wheat dominant 

species are absent; to a frequently met species belong: 



Aph‑

elenchus avenae, A. parietinus, P. rigidus, D. dipsaci, Chilopla‑

cus propinquus, Rh. brevispina, A. composticola, A. nanus, Ch. 

sclerovaginatus, P. subelongatus (total 10 species).

The species composition of plant nematodes, and 

soil rhizosphere of wheat is significantly different from 

each other both in terms of species composition and on 

the number of individuals. In wheat rhizosphere soil it 

was recorded 15035 nematode species belonging to the 

149 species. Of which often met
