Faunistic studies on terrestrial snails central part of Mazandaran province

The snails belong to the gastropods and are from the branch of mollusks. Terrestrial snails with regards to medicine, veterinary and agriculture are very important. An example is the white snail of gardens which according to reports cause big damage to the gardeners and farmers every year.The purpose of this study is to evaluate and indicate the phone of terrestrial snails in the central area of the province of Mazandaran. For this purpose the central area of the province of Mazandaran from Chaloos to Babolsarwere divided to eight stations. After nine months sampling from the gathered samples,for the aspect of morphology and systematically and using valid identification keys like identification keys of Bristol they were evaluated and identified by stereomicroscope .
In final according to the results obtained a number of 11 species of eight gender from4 family were identified.
Family: Enidae
Chondrolatridens(muller,1774)
Chondrulamaceadonica(wagner,1914)
Family: Helicidae
Candidulaspade(Calcara – 1845)
Candidulaitnteresecta(Poiret – 1801)
Vidoviciacaerolans( Pfeiffer – 1828)
Chilostomaillyricum( Stabile,1864)
Family: Hygromidae
Cernuellaneglecta(Draparnaud- 1805(
Cochlicellabarbara( Linnaeus- 1718 )
(Cernuella virgate(Darosta 1778
Family: Bradybaenidae
Fruticicolafruticum( Muller 1774)
Clausiliawateliana(Strobel ,1850)
Also the effect of environmental factors for example temperature and relative humidity on transmittance of the species was determined.
Considering the results obtained it was determined the province of Mazandaran had a relatively high diverse species and the temperature and relative humidity of the air had a special importance in the abundance and the distribution of the terrestrial snails in the region such that the most population of snails was evident in the temperature of 18 to 30 degrees of centigrad and the relative humidity of 60%
