Abstract

Grasses (Poaceae Barnh.) are damaged by many pest species, including slugs, especially by slugs from the genus Deroceras and Arion. These animals feed on seeds and green plant material near the surface of the ground and show a clear selectivity towards individual species, cultivars or forms of plants. So far, little research has been done on the food preferences of snails feeding on grass plants. In these studies, plants from five grass meadow and wheat (Triticum aestivum L.) species were exposed to Deroceras reticulatum (O. F. Müller, 1774) and Arion vulgaris Moquin-Tandon, 1855 feeding under laboratory conditions. There was a different variation in the magnitude of plant damage depending on the plant species and slug species. Higher susceptibility to damage was demonstrated by plants Poa pratensis and Festuca rubra contrary to plants Bromus wildenowii, Festulolium, Lolium multiflorum and Triticum aestivum.

 

Trawy (Poaceae Barnh.) są uszkadzane przez różne gatunki agrofagów w tym także przez ślimaki, zwłaszcza przez ślimaki nagie z rodzaju Deroceras i Arion. Zwierzęta te żerują na nasionach i zielonym materiale roślinnym w pobliżu powierzchni gruntu i wykazują wyraźną selektywność w stosunku do poszczególnych gatunków, odmian lub form roślin. Dotychczas wykonano niewiele badań dotyczących preferencji pokarmowej ślimaków żerujących na roślinach traw. W tych badaniach, w warunkach laboratoryjnych eksponowano rośliny pięciu gatunków traw łąkowych i pszenicy zwyczajnej (Triticum aestivum L.) na żerowanie ślimaków Deroceras reticulatum (O. F. Müller, 1774) i Arion vulgaris Moquin-Tandon, 1855. Stwierdzono zróżnicowanie w wielkościach uszkodzeń roślin w zależności od gatunku rośliny i gatunku ślimaka. Wyższą podatność na uszkodzenia przez ślimaki wykazały rośliny Poa pratensis i Festuca rubra niż rośliny Bromus wildenowii, Festulolium, Lolium multiflorum i Triticum aestivum.
