Abstract

Laboratory experiments were conducted to study the food preference and
consumption of certain vegetables for two species of land snails, Thebia pisana and
Eobania venniculata. Pdso, the study included the effect of vertimec (1.8% EC) against
the two mentioned species. The results proved that the lettuce was the most
preferable for the two species fdlowed by cucumber and carrots. In addition, the
gained data cleared that the squash was the lowest preferable for the tested species.
The consumption as a percentages were (45.45% and 46.1%) for lettuce, (20.9% and
14.6%) for cucumber, (182% and 25.8%) for carrots and (15.5% and 13.5%) for
squash for the two tested species T. pisana and Eobania vemiiculata respectively. For
the effectiveness of the concentrations used 0.06% and 0.11% of vertimec (1.8% EC)
against the same mentioned species, the results revealed that the mortality went up to
100% for both species at 0.11% concentration. Meanwhile, the concentration 0.06%
gave 40% and 45% mortality for Thebia pisana and Eobania venniculata respectively.
The moulluscicide compound cekumeta 5% (rnetaldhyd) gave complete kill after three
days and four days T. pisana and E. veimeculata respectively.
