Škůdci volně rostoucích a pěstovaných hluchavkovitých léčivek
Kočicová, Anna
I observed pests of Lamiaceae medicinal plants by visual inspection in the growing season of 2022 on two experimental areas. The first experimental area was the MENDELU arboretum, the second was the garden in Boleradice. 30 species of plants were monitored in area 1 (MENDELU arboretum) and 10 plant species in area 2 (Boleradice). A total of 711 individuals, 31 pest species, from 4 orders and 18 families were detected. 20 species of insects belong to the order of Hemiptera, 9 to the order of Coleoptera, 1 to the order of Orthoptera, and 1 Dermaptera. Aphids were the most nu-merous taxon (137 individuals). The representation of polyphagous, oligophagous and monophagous phytophages was almost identical on both experimental plots: polypha-gous 56–57%, oligophagous 42%, monophagous 1–2%. Phytophagous species detected on Lamiaceae plants reached a higher occurrence in the MENDELU arboretum than in Boleradice. No phytophages were detected on Salvia splendens, Nepeta cataria, Galeopsis segetum and Ocimum basalicum. The most attacked plant was Ballota nigra (104 individuals and 14 species). The monitored Lamiaceae plants were not seriously damaged, and therefore it was not necessary to use any regulatory measures against pests.
