 abstract={Population studies on Arion lusitanicus, a slug species introduced into Poland, were carried out over the last decade. The slug occurs commonly in some areas and spreads out relatively quickly. It has an annual life cycle with eggs, and immature individuals overwinter. In the end of July A. lusitanicus begins copulation and three weeks later it lays eggs from which the first offspring hatch within a month. The copulation process and egg laying last until late fall. One A. lusitanicus can lay over 400 eggs. During the growing season there are two peaks of population density. This species feeds on plant material such as leaves, stems, bulbs, but also consumes animal material. The basic plant material are arable crops particularly vegetables and some species of agricultural crops, some fruit trees, ornamental plants, herbs and weeds. A. lusitanicus displays apparent food specialization and prefers certain cultivated and wild growing plants. A. lusitanicus shows large reproduction potential, wide food and ecologic tolerance, and is regarded as a serious pests occurring in home gardens.},
