In: Zagazig Journal of Agricultural Research 2002.v.29(2)Summary: Five species of terrestrial snails were found infesting different crops in Sharkia Governorate. These species were Monacha cartusiana Muller, Helicella vestalis Preiffer, Cochlicella acuta Muller, Eobania vermiculata Muller and Succinea sp. The last species was recqrded for the first time in Sharkia Governorate. Relative occurrence of infested localities for each species was calculated in relation to total infestations with all species. The highest value was detected with M. cartusiana (77.14 %), followed by, C. acuta (7.31 %), E. vermiculata (5.60 % ), Succinea sp. (5.96%) and H. Vestalis (4.49 % ). Population density of land snail species was counted on host plants in a chosen localities at six districts of Sharkia Governorate. Generally, it was found that M. cartusiana was the predominant species on field and vegetable crops, while C acuta and H. vestalis were detected mainly on fruit trees.
