Based on over 3,500 dry shells and alcohol-preserved specimens from 77 localities, new records of 12 species (Truncatellina callicratis (Scacchi), T. himalayana (Benson), Boysia boysii (L. Pfeiffer), Vertigo antivertigo (Draparnaud), V. pseudosubstriata Ložek, Gastrocopta avanica (Benson), G. huttoniana (Benson), G. klunzingeri (Jickeli), Pupilla muscorum (Linnaeus), P. annandalei Pilsbry, P. turcmenica (O. Boettger), P. signata (Mousson)) are given; ten species (Columella nyrnphaepratensis sp. nov., Truncatellina ayubiana sp. nov., T. babusarica sp. nov., Vertigo superstriata sp. nov., V. nangaparbatensis sp. nov., Boysidia tamtouriana sp. nov., Papilla khunjerabica sp. nov., P. satparanica sp. nov., P. ziaratana sp. nov., P. paraturcmenica sp. nov.) are described. Shell variation is discussed for most species; the reproductive system is described and illustrated for nine species. Northern Pakistan, with its broader altitudinal range and generally wetter environmental conditions, has the highest diversity of pupilloids belonging to the genera discussed herein. Of the 22 species discussed in this report, ten species are currently considered endemic to Pakistan, the other 12 species being known from elsewhere in the region (Asia, Europe, and the Holarctic). The pupilloid fauna displays a high degree of Palaearctic/Holarctic influence at the generic level.

Balea fallax (Rossm.) collected from the Roztocze Upland (SE. Poland) was kept in the laboratory for four years. Observations were conducted between March and October when the snails were kept at room temperature (18-25°C); in winter they were stored at 3°C. The egg-laying period started in late March and lasted till October, with maxima in spring and early autumn. The snails laid oval, gelatinous eggs with separatecalcium carbonate crystals in the external envelope (average egg size 1.96 × 1.73 mm). The eggs were deposited in batches (up to 14 eggs at a time) or singly. The number of batches per snail per year ranged between 1and 4. Snails isolated before maturation laid defective eggs which failed to develop, which suggest that the speciesis incapable of uniparental reproduction or at least the ability is very limited. The reproduction rate decreased during consecutive years, probably as a result of the aging or the shortage of allosperm in isolated individuals.Compared to batches of typically oviparous clausiliids, eggs of B. fallax hatched slightly earlier (interval between oviposition and hatching lasted 8-10 days at room temperature). It is likely that the adults retained developing eggs in the uterus for a short time. The juveniles needed at least 6 months to attain the ultimates hell size.

A specimen of Trochulus hispidus from Buchenbach, Germany, had its male and female parts of thereproductive system completely separated. The female part lacked auxiliary organs. The male part opened into the genital atrium, but the vas deferens was blind-ended in a way precluding sperm transfer.

The experiments were carried out in Rzeszów, a region of the Arion lusitanicus mass occurrence, and also in Poznań. The studies were performed under field conditions, in isolators dug inio the ground. It was found that the slug began egg laying by the end of the first decade of August. The period of egg laying, depending on meteorological conditions, lasted for 2-3.5 months. The eggs were laid in clutches, each containing from 5 to 193 eggs. Most of eggs laid in August hatched before winter. For the eggs laid in mid-August the period of hatching was shorter than those laid at the turn of August/September, and the percentage of hatched eggs was lower. Eggs deposited at later dates (in September-November) did not hatch before winter.

W latach 1997-1999 prowadzono badania dotyczące terminu składania i wylęgania jaj Arion lusitanicus. W okresie jesienno-zimowym 1999 roku obserwowano także tempo wylęgania jaj złożonych w różnych terminach, procent wylęgłych jaj i długość okresu wylęgania. Doświadczenia założono w Rzeszowie, w rejonie masowego występowania ślimaka, oraz w Poznaniu. Badania prowadzono w warunkach polowych, w izolatorach wkopanych w ziemię. Stwierdzono, że ślimak rozpoczynał składanie jaj pod koniec pierwszej dekady sierpnia. Okres składania jaj w zależności od warunków meteorologicznych trwał od 2 do 3,5 miesiąca. Jaja były składane w złożach - od 5 do 193 jaj w jednym złożu. Do końca roku wylęgało się około 40% jaj. W badaniach jesienno-zimowych w 1999 roku stwierdzono, że większość jaj złożonych w sierpniu wylęgła się przed zimą. Dla jaj złożonych w połowie sierpnia okres wylęgu jaj był krótszy niż dla jaj złożonych na przełomie sierpnia i września, a procent wylęgłych jaj był niższy. Jaja złożone w późniejszych terminach (wrzesień-listopad) nie wylęgały się przed zimą.

Chemical composition of shells of Cepaea vindobonensis (Férussac) from sites with carbonate and carbonate-silica bedrock in central and south-eastern Poland and from alluvial deposits of the Vistula River indicates a relation between the chemism of the environment in which the species occurs and the chemical composition of the shells. The ability to accumulate heavy metals in the shell of C. vindobonensis makes this species a potential bioindicator.

Studies on palatability of some commom weed species, herbaceous plants and oilseed rape to D. reticulatum, A. lusitanicus and A. rufus slugs have been carried out under laboratory conditions. In food choice trials the rate and degree of damage to seedlings and leaf disks were determined for 20 plant species. The conducted experiments have also permitted to establish, which plant species were preferred or were not accepted by particular slug species. It was found that the studied slug species preferred seedlings and leaves of Brassica napus and Papaver rhoeas, but showed no preference for Epilobium hirsutum, Geranium sanguineum and Saponaria officinalis plants. As to the remaining plant species under study, the preferences exhibited by particular slug species were quite diverse.

Ślimaki (Gastropoda: Pulmonata) powodują duże szkody w rzepaku ozimym, pszenicy ozimej i w warzywach. Zwalczanie tych szkodników moluskocydami jest często mało skuteczne. Dlatego poszukuje się innych metod ograniczania ich szkodliwości, między innymi przez wykorzystanie różnych gatunków roślin, zarówno chwastów jak i ziół leczniczych lub naturalnych związków roślinnych. Wymaga to poznania atrakcyjności poszczególnych gatunków roślin i określenia ich wrażliwości na żerowanie ślimaków. Badania nad smakowitością niektórych pospolitych gatunków chwastów, roślin zielarskich i rzepaku oleistego dla ślimaków D. reticulatum, A. lusitanicus i A. rufus przeprowadzono w warunkach laboratoryjnych. W testach z wyborem i bez wyboru określono tempo i stopień uszkodzenia siewek i krążków liści, 20 gatunków roślin. W wyniku przeprowadzonych eksperymentów wyznaczono gatunki roślin preferowane i nie akceptowane przez poszczególne gatunki ślimaków. Wykazano, że badane gatunki ślimaków preferowały siewki i liście roślin: Brassica napus i Papaver rhoeas. Do roślin nie akceptowanych należały: Epilobium hirsutum, Geranium sanguineum i Saponaria officinalis. W stosunku do pozostałych gatunków roślin preferencje poszczególnych gatunków ślimaków były zróżnicowane.

Many sedge meadows in western Poland provide suitable habitats for Vertigo angustior Jeffreys and Vertigo moulinsiana (Dupuy) which are regarded as threatened across Europe. Such habitats are often subject to conservation measures aimed at supporting wetland birds in accordance with the European Birds Directive. Such measures, usually involving extensive mowing, may not favour the vertiginids. Both species are protected by another European act – The Habitats Directive. The range of methods used for maintaining the bird habitats is wide: the sites are mowed manually or mechanically in different ways, and the mowing covers the entire site or just selected patches. The aim of this study was to check how the different maintenance methods influenced the vertiginid populations. The abundance of V. angustior and V. moulinsiana was studied at 17 sampling sites along the Ilanka river valley (Lubuskie Province, W. Poland). The sites differed in size, moisture level, vegetation, type of land use and shadiness. The results suggest that extensive land management can be advantageous for botth species only when the site is divided in patches which are mowed alternately in consecutive years.
