Abstract :
Survey and distribution of land snail species at North western coast, Egypt were carried out, five species of terrestrial snails belonging to order Stylommatophora were found in different localities. These species were the glassy clover snail, M. cartusiana (Müller) the small sand snail, H. vestalis (Preiffer) the brown garden snail, Eobania vermiculata (Müller) The conical snail, C.acuta (Müller) and white garden snail T.pisana (Müller). The highest values determined with T. pisana in Maruit, Burg Elarab, Elhmmam area and, Nassora Manor as compared to low values in other districts.Seasonal population dynamics of C. acuta was studies on pear, fig and pomegranate during two succession years from March 2013 to February 2014 in North western coast. Data showed that individuals of C. acuta were found in the tested orchards throughout the year months. The lowest values of population density were detected during January and February. After then, numbers were gradually increased after winter months to reach the maximum values during summer months. Fig harbored the highest numbers followed by pear while pomegranate was the least one in this respect. The highest average of T. pisana was recorded on fruit trees, pear, fig, pomegranate and guava. Snails were active during all study periods, and it was obvious that maximum snail numbers were recorded in July.
