Survey and population dynamics of land snails at Sharkia Governorate, Egypt

Abstract

Land snails are a destructive agricultural pest in economic crops, but the populations for that pest are highly influenced by temperature and humidity, therefore climatic changes affected their behavior, distribution and population dynamics, for these reasons researchers should follow up on the changes in their behavior, distribution, and population dynamics. In this study, a survey study was conducted to define land snail species existing at Sharkia Governorate, Egypt, from January 2019 to March 2022 in horticultural, vegetable, and field crops and study the population dynamics for the dominant land snail species. Results showed that there are six species of land snails, these species were, Monacha cartusiana, Succinea putris, Eobania vermiculata, Theba pisana, Helicella vestalis, and Cochlicella acuta. The population dynamics of two prevalent land snail species (M. cartusiana and S. putris), were conducted during two successive growing seasons, the Egyptian clover harbored the highest number of M. cartusiana followed by wheat, while the onion was the lowest one during the study period. In the same trends, the land snail S. putris recorded the highest numbers during the growing season of the Egyptian clover crop. Finally, it is concluded that the land snail M. cartusiana considered the first grade of infestation existed everywhere at Sharkia Governorate, and the population density of the land snail is increase gradually after winter till reach the maximum density in spring.

“…According to Ismail (1997Ismail ( ), 2004Bayoumi et al, (2023), Eobania vermiculata species (Mollusca-Helicidae) are one of the most dangerous pests of numerous crops, vegetables, orchards, and ornamental plants.…”

“…The clover land snail, Monacha cantiana (Montagu), and the garden brown snail, Eobania vermiculata (Muller), are two of Egypt's most common and serious pests, causing significant damage to a variety of agricultural crops across the country. They were observed with a comparatively high population density on the major economic crops' Egyptian clover (Trifolium alexandrinum), cabbage (Brassica oleracea), lettuce (Lactuca sativa), and guava, (Psidium guajava) in Dakahlia governorate (Bayoumi et al 2023).…”
