An addition to the checklist of butterflies and moths (Insecta: Lepidoptera) of Ichnia National Nature Park (Chernihiv Region, Ukraine)

The additional data to the list of butterflies and moths of Ichnia National Nature Park is given. There are original records for 91 lepidopterous species from 78 genera of 12 families presented. Actually, 42 species from 37 genera of 10 families are recorded in the Ichnia National Nature Park for the first time. Recently the checklist of Lepidoptera of Ichnia National Nature Park and its immediate environs (taking into account the species from the previously published list) includes 633 known species from 379 genera of 31 families. According to the number of registered species, the following Lepidoptera families prevail in the fauna of Ichnia National Nature Park: Noctuidae (190 species from 99 genera), Geometridae (147 species from 83 genera), Tortricidae (70 species from 35 genera), Erebidae (36 species from 27 genera), Pyralidae (34 species from 25 genera) and Crambidae (24 species from 18 genera). The best studied is the territory of Arboretum ‘Trostianets’ of the National Academy of ciences of Ukraine (as a separate component of Ichnia National Nature Park), where 506 lepidopterous species from 302 genera of 21 families were registered. In other parts of the Ichnia National Nature Park 156 species from 133 genera of 27 families were recorded. It shows a lack of knowledge of its Lepidoptera diversity as a whole.

New data on the little-known species of the water scavenger beetle Helophorus pitcheri Angus, 1970 (Coleoptera: Hydrophiloidea: Helophoridae)

New records of weevils (Coleoptera: Curculionoidea) in Volyn Polesia (Ukraine)

An annotated list of new records of 45 weevil species is provided. Hadroplontus litura, Larinus iaceae, Magdalis exarata, Pissodes validirostris, Stereocorynes truncorum, Platystomos albinus, Nanophyes globiformis, Ceutorhynchus dubius, and Dorytomus suratus are registered in Ukrainian Polesia for the first time. 34 species are recorded in the west part of Volynian Polesia (= Volyn Region) for the first time. Total known richness of weevils in Volyn Region is increased by 9%. Currently, the list of Curculionoideae inhabiting Volyn Region includes 386 species and subspecies. Additional data on 11 species rare in Ukraine are given. The west range limit of Asproparthenis foveocollis is extended to Volyn Polesia. Discovery of Asproparthenis vexata in Volyn Polesia confirms coexistence of specific insect assemblages associated with endemic psammophilous flora. An alien Lygniodes bischoffi entered into Ukrainian Polesia presumably from Poland. The hornbeam, Carpinus betulus was detected as a new host plant of Cossonus cylindricus for the first time.

Improvement of the elements of chemical protection of spruce trees against spruce bud scales (Hemiptera: Coccidae: Physokermes) in ornamental plants’ arboreta in the Kharkiv Region

Chemical protection of spruce trees against spruce bud scales (spruce bud scale — Physokermes piceae (Schrank, 1801), small spruce bud scale — Physokermes hemicryphus (Dalman, 1826), and Hungarian spruce bud scale — Physkermes inopinatus Danzig et Kozаr, 1973) has been applied in arboreta in the Kharkiv Region for three years. The proposed protection system allows to effectively reduce the abundance of spruce bud scales or entirely relieve trees from them within 2–3 years period. System and complex insecticides with the addition of growth stimulator to the mixture contains were used for protection. Technical efficiency of tested insecticides is 90–97%. The optimal terms of protection have been determined which allows carrying out one treatment per season.

Communities of oribatids (Acari: Oribatida) in the agrocenoses in the vicinity of Dubliany (Male Polissia)

We investigated the taxonomic composition and structural specifics of the oribatids population in main agrocenoses’ types of Male Polissya. The studied communities are compared to the natural oribatid complexes based on literary data. In agrocoenoses, 14 oribatids species are found which belong to 10 families. Studied coenotic communities consist from 2 to 6 species of oribatid mites. There are 1 to 4 oribatid species per sample. The index of β diversity of oribatids in investigated agrocenoses is 5 times higher than in natural biotopes in the zone of deciduous forests. Comparative analysis of intra-coenotic H’ index of diversity shows that the largest contrast of intra-coenotic conditions for Oribatida was found in wheat agrocoenoses, the medium one in potato, corn, and soy coenoses, the smallest in rapeseed coenosis. Index of average oribatids population density in investigated agrocenoses varies in 30 times range of values. In investigated agrocoenoses genera of Oppidae, Mycobatidae, and Oribatulidae prevailed by species richness, each family is summarily presented by 2‒3 species. Analysis of H’ index for investigated oribatid groups shows that the smallest average diversity was noted in soya and rapeseed agrocoenoses, the largest in wheat coenosis. For 10 oribatid species, the potential to dominate is revealed in different types of investigated agrocenoses of Male Polissya. In some biotopes can be two to five dominating oribatid species. Six morpho-ecological types of oribatids are revealed. Structure of morpho-ecological (adaptive) oribatid types in agrocenoses is strongly different from that of the natural ecosystems of Ukraine. Agroecosystems are characterized by decreased diversity of the adaptive types of oribatids and the domination of non-specialized forms. We recognise three biotopical groups of oribatid mites in studied material: forest-meadow, meadow, and eurytopic species. The structure of ecological groups of oribatids is therefore reduced to three biotopical groups with the advantage of eurytopical representatives. Also in all types of agrocenoses eurybionic species group makes up 46‒87% of total quantity. As for hydropreferendum characteristics, only 2 to 3 ecogroups of oribatids found per coenosis.
