Abstract
V laboratorijski raziskavi smo preučevali kemično komunikacijo med parazitsko ogorčico polžev (Phasmarhabditis papillosa) in gospodarsko pomembnimi vrstami polžev v Sloveniji. Zanimalo nas je, kako se parazitska ogorčica P. papillosa odziva na dražljaje, ki izvirajo iz sluzi španskega lazarja (Arion vulgaris), velikega slinarja (Limax maximus), mrežastega slinarja (Deroceras reticulatum) in velikega vrtnega polža (Helix pomatia). Predvidevali smo, da pri različni temperaturi ogorčice različno intenzivno zaznavajo kemične snovi, ki jih izloča polžja sluz ter da različne vrste polžev z izločanjem sluzi različno intenzivno privabljajo ogorčice. Gibanje P. papillosa je bilo neodvisno od vrste polžje sluzi močneje izraženo pri višji temperaturi (20 °C), kot pri nižji (15 °C). Neodvisno od temperature je bilo gibanje ogorčic najintenzivnejše pri obravnavanju, kjer smo uporabili sluz velikega slinarja, ki je pri 20 °C na usmerjeno gibanje P. papillosa delovala kot atraktant. Pri primerjavi med različnimi vrstami polžje sluzi nobena sluz pri nižji temperaturi (15 °C) ni imela vpliva na usmerjeno gibanje P. papillosa. Pri 20 °C smo ugotovili, da sluz velikega slinarja in velikega vrtnega polža bolj privlači ogorčico P. papillosa kot sluz španskega lazarja in mrežastega slinarja.

Title:Chemotaxic response of the parasitic nematode (Phasmarhabditis papiollosa) to the mucus of economically important species of slugs in Slovenia
Abstract:
We have studied the chemical communication between the slug-parasitic nematode(Phasmarhabditis papillosa) and economically important species of slugs in Slovenia. We were interested in how the parasitic nematode P. papillosa responds to the stimuli, caused by the mucus of the following slug species: Arion vulgaris, Limax maximus, Deroceras reticulatum and Helix pomatia. We assumed that at different temperatures the nematodes sense the chemical stimuli, emanating from slug mucus, with varying degrees of intensity. We also assumed that different slug species attract the nematodes by eliminating mucus with varying degrees of intensity. Independent of the treatment, the movement of P. papillosa was more strongly expressed at a higher temperature (20 °C) than at a lower (15 °C). Independent of the temperature, the movement of nematodes was most intense in the treatment where we used the mucus of Limax maximus, which acted as an attractant on a directed movement at 20 °C. When comparing mucus of different slug species, none of them had an effect on the directed movement of P. papillosa at a lower temperature (15 °C). At 20 °C, however, the treatments have shown that the mucus of Limax maximus and Helix pomatia was more attractive to the nematodes than the mucus of Arion vulgaris or Deroceras reticulatum.
