Effectiveness of beer traps and molluscicides as means of gastropod control

Abstract

Twelve specimens of Truncatellina Lowe were found in May 2009 and April 2010 in the environs of Siemianówka and Bia³owie¿a (NE. Poland); five of them could be recognised as Truncatellina cylindrica (Férussac). In total 13 species co-occurred with T. cylindrica. Because of this recent finding, now 114 mollusc species are known from the Bia³owie¿a region
