| Survey and population studies were carried out in south district of Port Saied region, Port Saied governorate during 2010-2012. The survey revealed the existence of four species of land snails Monacha theba cartusiana, Monacha cantiana, family Helicidate and Succinea putris, Succinea elegans, family Succinidae on Egyptian clover, wheat and sugar beet. The population density of these land snails were observed on the soil, steams and leaves of tested crops, the results showed that the highest population were recorded on the soil around plants and under dead leaves and shelter of weeds and some on steams and leaves. The population density of all observed land snails was heavier on Egyptian clover followed by wheat and sugar beet, also recorded highest numbers through spring season followed by Autumn and Winter, also their egg clutches which affected by copper sulphate, super phosphate and low moisture of soil which irrigated after 25 days., Druart et al. 2011. On other hand, laboratoral studies were conducted on M. cantiana and S. putris in El-Serw Agricultural Research Station for measuring the influence of copper sulphate, super phosphate 15% and low moisture of substrate comprised by lannate 90 as recommended insecticides under laboratory conditions after one day initial effect and 3,5,10 and 15 days. The obtained data revealed that lannate 90 was more effective on S. putris than in case of M. Cantiana, copper sulphate recorded 72.8% and 65.6% on S. putris and M. catiana followed by superphosphate 15%, 65.6% and 56.8% respectively. While the lowest number of dead individual was recorded in dry substrate or low moisture (32.8% and 26.4) for S. putris and M. cantiana respectively. So, using safe materials such as copper sulphate and super phosphate 15% were more effective and acts as fertilizers, improving crop fields and quality without environmental pollution. | ||||
