Insects, and especially members of Hymenoptera order, have an important functional role
in natural, semi-natural, rural, and agricultural ecosystems. The success of the reproductive
strategy of many species of any flora depends on insects as pollination vectors. Valuating their
role in biodiversity supporting and providing ecosystem services are the important task of
modern ecology.
Current work aims to study the differentiation of insect-pollinated species in the flora of
National Natural Park “Pyryatynskyi” (Ukraine).
Studies of the flora of national park were conducted during 2008–2020 using floristic,
phytosociological, statistical, and population-biological methods. The flora of National Natural
Park "Pyryatynskyi" includes 1174 species of higher vascular plants from 509 genera, 122
families, 55 orders, 16 subclasses, and 9 classes belonging to 6 divisions of the plant kingdom.
Each plant species was analyzed according to its type of pollination and attribute to the
fractions of flora and coenoflora.
Entomogamy is the dominant type of pollination in the flora of the national park. Insects
are an important vector of pollen transfer for 838 species of angiosperms (71.3 %). The number
of species with anemogamy (313; 26.6 %) in the flora is significantly lower. There are 11.1 %
(135 species) of species with autogamy. Water-pollinated species are a minor component of the
flora (44; 3.7 %). Similar relationships between species by type of pollination were obtained
for the flora of the Carpathian Highlands, Danube Biosphere Reserve, the natural flora of Central
Asia, and are characteristic features of the flora of the Holarctic floristic kingdom.
Native and non-native components of the flora are almost indistinguishable according to
the differentiation of species with a different type of pollination. Among alien species,
hydrogamy is almost completely absent (2; 0.9 %), but the role of self-pollinated plants is
increasing (31; 14.9 % compared to 104; 10.7 % for the aboriginal flora fraction).
Entomogamy is an equally important method of pollination in both the adventive (154;
74.0 %) and an aboriginal fraction of flora (684; 70.7 %). However, significant deviations from
these proportions are fixed in coenofloras.
Thus, in the coenofloras of the classes Lemnetea, Littorelletea uniflorae, Potametea,
Phragmito-Magnito-Caricetea, and Scheuchzerio-Caricetea nigrae the ratio of the species with
anemogamy and entomogamy is almost 1:1.
In communities of the class Bolboschoenetea the relative number of insect-pollinated
species is even smaller than a number of species with anemogamy.
The role of insect-pollinated plants in the communities of the classes Trifolio-Geranietea,
Carpino-Prunetea, Festuco-Brometea, and the order Galietealia veri is especially high.
Entomogamy is the leading type of pollination in the flora of NPP "Pyriatynsky", its
aboriginal and adventitious faction. The study of the taxonomic structure of pollinators is an
important task for the conservation of vegetation of nature reserves.

Keywords: flora, entomogamy, insect-pollinated species, National Natural Park "Pyryatynskyi".
