“…Its mucous causes also unfavorable smell could prevent men and farm animals from direct feeding on crops (Sallam et al, 2009;Abo Zaid et al, 2021). Snails also have increased markedly and causing huge damage for different field crops in many Governorates of Egypt (Eshra, 2014;Eshra et al, 2015;Abou Senna et al, 2016;Fathey, et al, 2020).…”

Field experiments had been conducted using different pesticides commonly used on vegetable crops searching for suitable compound could be successfully used in controlling of the glassy clover snail, Monacha cartusiana, during the activity period at Sharkia Governorate. The obtained data clearly showed, the percent reductions of snail under field conditions were significantly differed from one pesticide to another and from vegetable crop to another more over the date of examination after application was also affected in addition to; densities of infestation, the crop cultivation rates, ecological behavior of the snails and types of dispersion in each crop. Since, the tested pesticides reduced snails' population in squash with varying degrees, the general means of percent reduction three days after application recorded maximum reduction with malathion and methomyl with 57.26 and 53.61% reduction, while the least effects were recorded with imidacloprid and acetamiprid with 31.25 and 27.07%. The same trend was observed two and three weeks after application with a slight increase or decrease in reduction percentages with all tested compounds. On the other site, the tested pesticides reducing populations on cabbage one week after application with maximum reduction by methomyl and malathion, 56.09 and 52.51%, while the least effects were recorded with acetamiprid and imidacloprid with 30.61and 26.51% reduction, respectively. When regarding reducing in snails' populations on eggplant three weeks after application, the highest effect was recorded with malathion; moderate effect was with fipronil while imidacloprid showed the least effect in reduction. As soon as, on tomato one week after application, the reduction recorded with malathion was 57.25% followed by methomyl 53.60%, while with imidacloprid 31.25% and acetamiprid 27.07% reduction percentages. On green pea the efficacy of pesticides after the third week of application reducing the populations with highest effect by methomyl; moderate effect with fipronil while the least effect recorded with imidacloprid. While in spinach one week after application the reduction percentages recorded 59.24% with methomyl, 55.47% with malathion, 32.33% with acetamiprid and 28.01% reduction, with imidacloprid moreover the same trend was observed two and three weeks after application. Generally, the molluscicidal determination of all tested pesticides in controlling the glassy clover snail, M. cartusiana infesting vegetable crops under field conditions at Sharkia Governorate could be arranged as; total general means of percent reduction, after four weeks of application as follows:

“…Snails have increased and became real pests, causing considerable damage especially for horticultural crops (Heikal, 2015). Several species of these snails were registered in many Governorates of Egypt (Eshra, 2014;Eshra et al, 2015;Abou Senna et al, 2016;Ali and Robinson, 2020).…”

The use of chemicals to control land snails can lead to environmental pollution, hazards to humans and toxic residues in agricultural products. Therefore, finding safer alternatives for managing these pests has become a priority. Field experiments were conducted to test different methods for controlling Eobania vermiculata snails infested navel orange trees in Dakahlia Governorate. These methods included ploughing during the egg-laying period in January, planting cabbage traps in February, applying attractive materials in March, using pesticides in April during the activity period, and hand collection during aestivation period in June. The ploughing process significantly (P≤ 0.05) reduced the populations of E. vermiculata. One week after ploughing, the number of snails per sample decreased from 29.22 to 11.76, representing 63.87% reduction. After six weeks, the overall reduction in population was 40.73%. Planting cabbage traps also decreased the snail populations, with a maximum reduction of 68.54% after six weeks. Attractive materials had a significant effect on attracting populations. Sugar-cane syrup and barley powder showed the highest effectiveness, with reductions of 66.05 and 54.12%, respectively. Boiled potatoes had a moderate effect, while vanilla powder was the least effective one, with a reduction of 39.92%. Biocides and plant extracts had a significant effect on the suppression of snail populations. Oikous and clove oil had the highest effect, with 46.05 and 42.56% reduction, respectively. Protecto showed a moderate effect, while eucalyptus oil was the least effective one with 28.21% reduction. The application of pesticides also reduced the snail populations to varying degrees. The molluscicidal efficiency of the tested pesticides could be arranged in descending order after three weeks of application as follows: methomyl < fenamiphos < deltamethrin < oxamyl, with reduction percentages of 60.30, 54.41, 48.81 and 39.03%, respectively. Hand collection during the aestivation period in June also significantly (P≤ 0.05) decreased populations, with a 46.41% reduction as a general mean during the six-week experimental period. Generally, all tested control methods significantly reduced the populations of E. vermiculata in navel orange orchard from January to July. Based on the general means of percent reduction, the tested methods can be arranged in descending order as follows: cabbage traps, pesticides, attractive materials, hand collection, ploughing, and using biocides besides plant extracts.
