Survey, Population Dynamics and Estimation of Damage of Common Land Snail Species on Some Vegetable Plants and Egyptian Clover at Some Regions at Kafr El-Sheikh Governorate

Abstract

Survey and population dynamics were carried out in two regions, Abu-Abdalla village, Sedi Salem District and Salait village, Quallen district at Kafr El-Sheikh Governorate during two successive seasons from 2015to2017 on egyptian clover, lettuce, and cabbage. The survey revealed the existence of four species of land snails, Monacha cantiana, Succinea putris, Theba pisana and Cochlicella acuta were predominant on egyptian clover and two vegetables crops. The population densities of these land snail species were studied on soil, stems and leaves of studied plants. The results showed that the highest population was recorded on leaves under field of vegetable plants during spring seasons except cabbage at Abu Abdalla, Sedi Salem district in 2015 and 2016. T.pisana presented in Lettuce and and Cabbage on Abu-Abdella village and was absent on all vegetable crops on the second village. while M. cantiana ,C.acuta and S.putris snails were recorded with highest numbers on Egyptian clover. On the other hand, S. putris was in heavy infestation on lettuce and cabbage in the two regions. The damage caused by different snail species M. cantiana and S. putris was studied on Egyptian clover.

Taxonomic Key as A Simple Tool for Identifying and Determining the Abundant Terrestrial Snails in Egyptian Fields (Gastropoda, Pulmonata: Succineidae, Geomitridae, Helicidae, Hygromiidae)

“…Generally, the species Succinea sp. documented in South district of Port Saied, Port Saied governorate (Awad, 2013), Ismailia and Sharkia (Rady, 2014), Qalyubia, Monufia, Sharkia, Damietta, and Dakahlia (Mohammed, 2015), and Kafr El-Sheikh governorate (Gazzy et al 2019).…”

“…Succinea sp. had been recorded on lettuce, Egyptian clover, rice, broad bean, pea and cabbage (Mohammed, 2015;Heiba et al, 2018;Gazzy et al, 2019) and also recorded mainly on field and vegetables, and not had recorded on ornamental plants or wood trees in Kafr El sheikh governorate (Heiba et al, 2018). In this study, Succinea (Amphibina) Cleopatra found on Chicory Cichorium pumilum and Egyptian clover Trifolium alexandrinum at El Qanater El Khayreya (coordinates 30°11.601' N 31°06.693' E) ( Fig.…”

“…The species is recorded in Qalyubia, Gharbia, Monufia, Damietta, Ismailia and Kafr El Sheikh governorate (Kassab and Daoud 1964;Mohammed, 2015;Heiba et al, 2018;Gazzy et al, 2019;Mostafa, 2020), Cairo (Mohamed and Ali, 2011), Beheria governorate (Eshra, 2013), and recorded in some desert spots in King Mariout and Borg El Arab, Alexandria (Ali, 2017).…”

“…The species had been recorded on grapes, mango and date palm in Qalyubia, Gharbia, Monufia, Damietta, and Ismailia (Mohammed, 2015) on lettuce, Egyptian clover, cabbage and broad bean in different governorates (Heiba et al, 2018;Gazzy et al, 2019) and on guava trees orchards in Kafr El Sheikh governorate (Mostafa, 2020).…”

“…Terrestrial gastropod surveys had been recorded around Egypt (Hashem et al, 1992;El-Deeb et al, 1996;Abd El-Aal, 2001;Mortada, 2002;Idress, 2003;Sallam and El-Wakeil, 2012;Mohammed, 2015). The species varied in level of infestation according to locality weather and environment and host type (Gazzy et al, 2019). The habitat characteristics such as vegetation, organic matter and soil structure can be important for species abundance.…”
