Dates of overwintering, mating, egg-laying, hatching and population peaks of the slug were observed on six sites located in horticultural habitats, as well as in the isolation cage, where slugs were reared. It was ascertained that A. lusitanicus has a year-long life cycle. The slug overwinters in the form of eggs or juvenile stages and rarely as adult individuals. Young slugs leave their winter shelters by the end of February. The mating period starts in the second half of July and lasts from 6 to IO weeks. Eggs are laid from mid-August till late autumn. Slug hatching occurs in spring and autumn at the time of plant sprouting.}, type={Article}, title={Periods of occurrence and fecundity of Arionlusitanicus Mab.
