Land snails especially Monacha cartusiana and Helicella vestalis caused many problems to most of
the economic plants in Egypt. The presented study was carried out to estimate the susceptibility and
consumption rates of snails infesting cabbage (Brassica oleracea var capitat), lettuce (Lactuca sativa),
egyptian clover (Trifolium alexandrinum) and orange (Citrus sinensis) plants. Besides, certain elements of
these plants were analytically assessed. Data showed that cabbage and lettuce were most attracting
compared to other plants [(63.3, 67.3) and (57.9, 42.9) individuals] for the two snails, respectively.
Cabbage and lettuce had, also, the highest quantity consumed by two species of snails with means (34.8,
41.5) and (30.9, 33.3) gm., for the two animals, respectively. Results cleared that cabbage has the highest
percentages of protein, sugar, carbohydrates, P and Na elements, while orange has the least percentages of
most elements. |
