representative samples. The long-term faunistic studies of different stages of the forest-
steppe agro-landscapes, performed by us in the framework of postgraduate theses,
made it possible to determine the presence or absence of certain species in the
entomological assemblies and compare the results of the species diversity with the
literature data (see Table 1).
For life forms, insects are distributed as follows: geobionts: known species – 107
of 5 rows and 13 families, the present state – 59 species of 4 rows and 11 families.
Herpetobionts: well-known species – 470 out of 6 rows and 30 families, the current
state – 134 species of 4 rows and 30 families. Hortobionts: known species – 173 species
of 7 rows and 42 families, the present state – 107 species of 7 rows and 29 families.
Dendrobionts: known species - 854 of 13 rows and 136 families, the present state –
480 species of 12 rows and 113 families.
The analysis of the structure of entomological biodiversity has shown that the
number of entomofauna decreased from 1604 species to 780 species (see Table 1).
It should be noted that this is a personal study of the authors, which does not take
into account the data on the entomofauna of hydrobionts, since the methods of
recording and identification are more complex than terrestrial entomophases. More
than 40% of insects are not marked out from the known entomofaun of agrocenoses,
since many species are in very small numbers (single specimens) and to catch them or
to detect a long time and a large team of entomologists. The specification of the number
and species composition of the entomofaun of the forest lands of the agrolandscapes
should become the main task for postgraduate students and scientists of the
entomological and ecological profiles. Our task was to create methodological
approaches to the study of entomological biodiversity in the forest lands of the
agrolandscapes and to focus on the size and condition of insects today.
Geobionts. Analytical studies have allowed to compile a register of dominant and
constant species of insects-geobionts of forest landscapes of agricultural landscapes. It
was established that entomological biodiversity of geobionts was 107 species and
consisted of 6 rows, which included 13 families. The taxonomic analysis of the
entomofaun showed that the largest number of families had a number of Coleoptera
(8), which was 93.38% of the total. The families of Dermatoptera and Homoptera were
2 in the family, which was 5.6%, while Isoptera, Orthoptera had 1th family. The most
abundant species were the Curculionidae, Carabidae and Scarabaeidae families: 32, 27,
18 species, respectively. This is due to the fact that in the larvae of these types of habitat
there is a soil, where before the exit of the imago they spend a fairly significant period
of life cycle – from 2 to 4.5 years. The families Termitidae, Gryllotalpidae, Alleculidae
and Tipulidae had the first species.
As a result of faunal studies, 59 types of insects-geobionts were caught, identified
and systematized, which belong to 11 families of 4 rows. The largest number of species
- 1347 -
