Abstract

The fungicidal activity of M. anisopliae was assessed against M. carlusiana
and E. vermicu/ata land snails in ccmpared with the carbamate insecticide Methomyl.
Results revealed that M. snisop/ise at concentrations of 0.5 x10^s , 1 x10~ ,2x10^s and
4 x10^s spore I ml Induced (32.14,53.57,75 and 92.86 %) and (28.75,50,67.86
and 85.71 % ) mortality against M.csrlusians and E. vermicu/ata land snails after 7
days exposure period, with LC50 values of (0.873 x11f and 1.071 x10' spore I ml)
respectiVely. In contrast Methomyl at concentrations of 0.5, 1, 2 and 4 % as poison
bait, exhibited (26.66, 53.33, 66.66 and 86.66 %) and (40, 76.66, 90 and 96.66 % )
mortality after 7 days against the two tested snails species, with LC50 values of
(0.819 and 0.475 % ), respectively.
