Ecological and control studies were conducted on Monacha cartusiana Muller infesting cotton seedlings at Sharkia Governorate. Results assured that the land snail, Monacha cartusiana attack cotton seedlings during the first stages post emergence until the end of May. Regarding dispersal of M. cartusiana snails to cotton fields, results revealed that the population density of snails and percent of infested seedling were concentrated in the adjacent areas to clover fields and decreased gradually far from to the site of infestation. The same trend was observed at 10 and 20 m far from the adjacent Egyptian clover field. Percent of infested seedlings reached the highest value in April, while the lowest value was found in May. It's necessary to mention, that snail infestation did not appear in cotton cultivation after May. Methomyl and metaldehyde were evaluated against ill. cartusiana snail under field conditions. Metaldehyde was more effective than methomyl in controlling the land snail, M. cartusiana infesting cotton seedlings.
