It’s dispersion and this occur by studying all thing about it’s life and make a suitable programs for managing it. Until now, mostly these pests were controlled chemically by using molluscicides or pesticides which present the main reason of the environmental pollution, this by it’s accumulation in soil, water, air and in the agricultural products. All this disadvantages leads to searching for a new safety methods for the management of this pest as the biological control using the microorganisms. Terrestrial gastropods (snail and slug) species were subjected to an extensive occurrence survey during the period from September 2010 to August 2012 in 25 localities (villages) representing five districts (the countries) of Kafr EL-Sheikh Governorate. Ten herbivorous species (eight land snail and two land slugs species) belonging to three families of order: Stylomatophora were collected (the conical snail, Cochlicella acuta; the brown garden snail, Eobania vermiculata; the small sand snail Helicella vestalis; the glassy clover snail, Monacha cartusiana; Monacha cantiana and Monacha obestructa, the small amber snail, Succinea oblonga and the amber snail Succinea putris, the field slug Deroceras reticulatum and marsh slug Deroceras leave).
