Due to the importance of Monacha cartusiana as a major herbivorous pest, a study was conducted in Kafr El-Sheikh to estimate its population density and damage to sugar beet fields, alongside evaluating pesticides to reduce its spread. Data revealed that the snail population density was lowest in mid-February, with a mean of 9.0 ± 1.41. The population gradually increased from late February to mid-March, reaching a peak density of 148.4 ± 11.16 by the end of March on sugar beet crops. The study observed that M. cartusiana snails caused increasing damage to sugar beet leaves, starting with a damaged area of 10.95 ± 0.85 mm² by mid-February. This damage escalated over the following weeks, peaking at 544.11 ± 81.36 mm² by late March, representing 22.57% of the leaf area. However, by mid-April, the damage significantly decreased to 25.40 ± 5.93 mm² due to a reduction in the snail population. The toxicity results indicated that the oxamyl compound was the most toxic, with a LC50 value of 0.26% and 495.80 ppm, compared to the rest of the compounds when using the baits and residual film methods under laboratory conditions, while in the field, the oxamyl compound gave the highest mortality rates, followed by Azoxystrobin, Sodium tripolyphosphate and Propiconazole with values of 97.35%, 92.01 and 74.12 and 64.96 after 21 days of treatment, respectively. Also, pathological symptoms clearly appeared in the treated individuals compared to the control.
