.Land snails attacking sugar beet fields: I- Population density, damage and losses caused by Monacha cantiana snails at Kafr El-Sheikh governorate

Abstract: This study was conducted at Kafr EI-Sheikh Govemorate during two successive seasons, 2005 / 2006 and 2006 / 2007 to determine the population densities of the dominant land snails and estimate damage and losses due to M.cantaina on foliage, roots yield and reduction in sugar contents.
Results revealed that the population density of M.cantiana snails on sugar beet in the three times of plantation were slightly [(2.6, 3.6 and 2.8 ) and (2.3, 1.8 and 7.4)] and [(6.9, 6.0 and 13.5) and (3.2, 3.6 and 10.6)] individuals / m2 at Kafr ElSheikh and EI-Hamol districts, in the beginning of seasons 2005 / 2006 and 2006 / 2007, respectively. Then, population increased gradually until reached maximum numbers in the end of seasons with values of [ (26, 51 and 62) and (26, 66.2 and 60 )] and [(29, 22 and 70) and (29.6, 30.4 and 76.5)] individuals / m2 at two districts in the three times of plantations at the two successive seasons 2005 / 2006 and 2006 / 2007, respectively.
Results indicated that the damage and losses assessment due to different levels infestations of M.cantiana (10,20,30,40 and 50 snails / plant) resulted in considerable damage to sugar beet under field conditions. The general mean of reduction to foliage, root weight and sugar yield were (0, 0.128 and 1.06), (4.30, 1.41 and 3.19), (9.09, 1.92 and 9.57), (19.13, 2.56 and 11.17) and (23.44, 3.46 and 12.23) for infestation levels of 10,20, 30, 40 and 50 individuals / plant, respectively during 2006 / 2007 season.
