| Abstract | ||||
| This study was carried out on certain districts at Sohag governorate, Egypt to survey and population density of some species of land snails and slugs infesting field crops, vegetable, fruit trees and ornamental plants. Results revealed that most crops highly infested with Monacha obstructa snail, while Eobania vermiculata, Oxyloma elegans, Deroceras laeve and Lehmannia valentiana had moderately to low infestation. As in the case of O. elegans, D. laeve, L. valentiana and L. flavus, they were recorded for the first time at Sohag governorate. Seasonal fluctuation of M. obstructa was obvious that the highest numbers of were recorded during Spring season (March, April and May) on fruit trees (mandarin, orange and mango), as compared to population density during the other seasons (Winter, Autumn and Summer). | ||||
