Summary: Helix aspersa, known as garden snail, is a species of land snail, a pulmonate gastropod. This snail is very common and widespread in Mediterranean region and western Europe. This species is characterized by a spherical in shape shell with a short spire and a rough surface. The shell color is pale brown, or yellow with a number of broken dark bands, which give the shell it, is blotchy appearance. This study investigates the effect of temperature on phagocytosis activity in garden snails H. aspersa. Low and high temperatures depressed phagocytosis activity and decrease the number of yeast cells phagocyted by H.aspersa hemocytes. The phagocytosis activity at 25Co is (50.8±4.5), 35 Co (19.2 ± 3.9), 40 Co (3.6±0.89), and 15 Co (4.4±1.1).Two types of hemocytes cell GLC (Granulocyte like Cell), and HLC (Hyalinocyte like Cell) are diagnosed
