The number and degree of seedling damages were estimated on the basis of the intensity of slug occurrence, which were caught in baited traps. It was found that over a 3-4-week period after sowing, damages caused by D. reticulatum slugs constituted 60% in young oilseed rape and 40% in wheat plants. Under laboratory conditions, one slug damaged almost completely 10 rape seedlings (95%) during 13 days of its feeding. The percentage damage caused by the pest to wheat seedlings was considerably lower (53%), whereas wheat seeds appeared to be severely damaged (83%) after 9 days of the slug feeding.}, type={Article}, title={Assessment of plant damages and intensity of Deroceras reticulatum (Muller) occurrence in winter oilseed rape and winter wheat}, URL={http://www.czasopisma.pan.pl/Content/131065/PDF-MASTER/7_PLANT_42_3_2002_Kozlowski_Assessment.pdf}, keywords={Deroceras reticulatum, harmfulness, oilseed rape and wheat}, }
