| Abstract | ||||
| The activity of certain pesticides were evaluated against Monacha cartusiana and Eobania vermiculata land snails under laboratory and field conditions at Oakahlia Governorate using poisons bait technique. Laboratory experiment revealed that Neomyl exhibited the highest toxic action against M.cartusiana snails followed by Vertimec, Marshal, Dursban, while Curacron was the least toxic one. Values of LC50's were 0.44, 0.54, 1.67, 3.69 and 4.67 % respectively. In respect of E vermiculata snails LC50's values of the same tested compounds were 0.64,0.65,2.94,4.73 and 10.14 % for Vertimec, Neomyl, Marshal, Dursban and Curacron, respectively. In field experiment Neomyl and Vertimec were tested against M.cartusiana on Egyptian clover crop and E vermiculata infesting ornamental plants with 1, 2, 4 and 8 % concentrations. The initial and residual activity of the two tested compounds were [(42 and 66.33 % ), (51 and 75.66 %), (55 and 83.33 %) and (62 and 89.66 % ) ] and [(24 and 45 %), (31 and 55.66 %), (35 and 64.66 %) and (40 and 72.66 %)] reduction after 3 and 21 days post-treatment for M.cartusiana snails respectively, while against Evermiculata snails were [(31 and 54.66 %), (38 and 74.33 %), (52 and 82.33 %) and (57 and 88 %)) and [(44 and 47 %), (49 and 58.66 %), (51 and 70.66 %) and (58 and 81 %)]reduction respectively. | ||||
