Curculionidae – 15 against 32 (2.1 times); the family Silphidae and Forficulidae – 1
against 2 (2 times).
The results of the research suggest that substantial changes have taken place in
the entomocomplex of geobionts. Thus, the number of insect rows has decreased from
6 to 4, families – from 13 to 11, species – from 107 to 59.
As a result of analytical studies, it was found that at the end of the twentieth
century, a set of insect-herpetebionts of forest-steppe agrolandscapes comprised 470
dominant and constant species. The variety of insects consisted of 5 rows, which
included 30 families. The largest number of families had rows: Coleoptera – 17 and
Hemiptera – 7. The largest number of species had families: Curculionidae – 231;
Carabidae – 126, Staphylinidae – 18, Elateridae and Chrysomelidae – 15 species. For
these families, 85.9% of all species of entomophases of herpotobionts accounted for.
According to faunal studies, the modern entomocomplex of herptobionts includes
134 species belonging to 30 families of 4 rows. Among the common insects dominated
by representatives of the Coleoptera (64.05 %), Hemiptera (34.91 %), Orthoptera
(14.58 %) and Hymenoptera (7.64 %).
The interstitium, the antlers of the family Formicidae, the most abundant of which
are noted Lasius niger L. – 43,5% and Tetramorium caespitum L. – 34.5 %.
Representative Coleoptera more diverse: include families Carabidae – 28 types (20.9
%), Curculionidae – 22 (16.4 %), Elateridae – 14 (10.4%), Chrysomelidae – 10 (7.5
%), Staphylinidae – 7 (5.2 %), Tenebrionidae – 8 (6 %), Silphidae – 4 (3 %), Leiodidae
and Histeridae – 3 (2.2 %), Mordellidae, Cicindelidae, Anthicidae, Cerambicidae –2
(1.5 %), Coccinellidae, Apionidae, Dermestidae – 1 type (0.7 %). This way the family
is dominant Carabidae, which includes breeds: Harpalus, Calathus, Pterostichus,
Bembidion, Amara, Poecilus, Carabus and etc. which includes breeds Harpalus – 6
types (4.4 %) і Calathus – 4 types (2.9 %). Among family Harpalus dominates
Harpalus affinis S. – 30 % and Harpalus distinguendus D. – 17 %, breed Pterostichus
– Pterostichus melanarius B. – 25% and Pterostichus niger Schall. – 23 %. A
comparison of the results of analytical and faunal studies suggests that the decrease in
the variety of herptobionts by almost 3.5 times.
Hortobionts. According to the results of analytical studies, the diversity of insects-
hortobionts consisted of 7 rows, which included 42 families that numbered 173 insect
species. The number of families in the ranks was dominated by a number of Homoptera
(11 families). The smallest family was Thysanoptera (2 families). The richness of
families of the Lepidoptera family (10 families) should also be noted. But for the
abundance of species, the level of dominance of different rows significantly differed.
Thus, the number of Lepidoptera has 47 species, Homoptera - 39 species. The least
abundant was the Hymenoptera series – only 7 species of insects from 2 families. The
Thysanoptera number comprised only 2 families, but they included 30 species.
