Damages of seeds of different cultivars of lupines causedby slugs Arion vulgaris Moquin Tandom, 1885, Arion rufus (Linnaeus, 1758)and Deroceras reticulatum (O.F. Muller, 1774)

摘要

Feeding of slugs on lupine seeds creates potential threat to crop yield, but detailed information on the extent of the damages is limited. The aim of the research was to evaluate damages on different cultivars of lupine seeds caused by slug feeding. Twenty one cultivars of lupine were exposed to feeding of slugs Arion vulgaris, Arion rufus and Deroceras reticulatum under laboratory conditions. Within the ten days of observation the degree of seed damage caused by slugs was determined using a scale. It was found that each species of slug had a different food preferences in relation to the cultivars lupine and this is the reason for the significant variability of susceptibility of cultivars to slugs damages.
