| Abstract | ||
| Field studies were conducted in seven districts representing Dakahlia Governorate, during 2003 , 2004 seasons to determine the economic importance value of land snail and slug species infesting major crops using some ecological parameters. Results revealed that Eobania vermiculata Muller achieved the highest economic importance value species (48.761), whereas Monacha cartusiana Muller ranked the second with value of (46.852), followed by Limax f1avus with (45.974), Helix ap < /em>erta Born. (40.887), Succinea putris L. (21.357), Succinea oblonga Draparnaud (20.032), Cepaea hortensis Muller (16.596), Deroceras reticula tum Muller (16.9), Deroceras laeve Muller (14.231), Lehmannia marginata Muller (10.055), Cochilcel/a acuta Muller (9.409) and Oxychilus al/iarius Muller (5.722) the species Ruminna decol/ata L. showed the least economic importance value (3.224). An importance value of any land snail and slug species differed according to plant species and time of the year (season). | ||
