CONCLUSION
1.
An estimation of the entomofauna state of agrolandscapes is possible on the
example of a representative sample of insects, which is represented by the constant and
dominant species introduced into the entomological registries created in the past
century. For the optimal generalization of the samples, it is advisable to group
agrolandscapes into an entomofauna according to the basic forms of life (geophils and
phytophiles), each of which requires adequate methods of counting the numbers.
Comparison of the results of analytical and faunistic research will allow us to assess
the natural dynamics of Ukraine's diversity.
2.
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.
3.
Based on long-term faunal studies, impoverishment of the species
entomological diversity of geobionts by 44.9 % and herpetocytes by 71.5 % has been
proved. By reducing the diversity of geophils, the proportion of phytophiles has
increased at present, from 10.8 to 13.7 % in hortobionts, and from dairies to 53.2 to
61.5 %. However, the species diversity of insects decreased, respectively, by 38.2 %
and 43.8 % respectively.
4.
On average, the indicator of the species' entomological variety of agro-
landscapes of the forest-steppe of Ukraine has decreased by 49.6 %. Reducing the level
of diversity to a greater extent was due to insects-geophils (geobionts and
herpotobionts), which reflects the significant ecological disturbances of the
pedosphere. The obtained data show that about 50 % of insect species, which in the
past had the status of constant and dominant in agrolandscapes, as a result of the
adverse environmental factors became small, which is the first step towards their actual
disappearance.
