The present study was carried out for survey and identication for ran-dom land snail in 11 districts, i.e.  (Tema, Tahta, Gehyena, El - Maragha, Saqultah, Sohag, Akhmim, El - Monshah, Gerga, El - Balyana, and Dar El - Salam) at Sohag Governorate, Egypt. Samples were collected from 5 different locations in each district during 2016 - 2017 seasons. The monthly samples were taken from winter and summer crops (areas were cultivated with the eld crops such as wheat, Egyptian clover, and vegetables crops. The results showed that found two spe-cies of land snails, Monacha obstracta  (Montagu) and Eobania vermiculata  (Muller). It was also observed that the occurrence of the spread of land snails was increased from the previous peri-ods. The results further indicated that land snails were recorded in Sohag for a second time more widespread and may be that this pest moved to these governorates with transportation, passengers from places spread these new places and happened to her adaptation and after have transferred from infestation regions so, have adapted under weather factors of new re-gion also, several factors e.g., the presence of more preferable food, shelter, intra - specic com-petition, fecundity increasing, several hosts or habitat in the new ecosystems. Therefore, this study gives an interesting indication of the development of a plan in effective strategy for land snail’s management program in agro ecosystems in Upper Egypt. ©2018 Agriculture and Environmental Science Academy   Keywords   Egypt   Eobania vermiculata   Land snails   Monacha obstracta   Terrestrial gastropods   Citation of this article: Desoky, A.S.S.

Land snails cause heavy damage was manifested in chewing soft veg-etative growing, the owers and fruits, also eating seeds, roots and tubers after the sowing or during repining. (El - Okda, 1980; Imevore and Ajayi, 1993; Ismail et al ., 2003; Ramzy, 2009). In addition, the movement of snails causes an unwanted smell which avoids men and even animals from feeding on these pol-luted plants (Sallam et al ., 2009). Furthermore, some gastropods work as intermediate hosts for many parasitic worms infesting man and his domestic animals (Barker, 2001).   In Egypt, the land snails dispersing in northern Governorate, Alexandria, El - Beheira, Kafr El - Shikh, and Domietta (Kassab and Daoud, 1964; El - Okda, 1980; Hashem et al ., 1993; and Eshra, 2103 ) At the present time these snails distribute in Ismaellia, Sharkia, Monoa, Gharbia, Minia, and Assiut Governorates (El - Deeb et al ., 2004; and Shoieb, 2008). Nine terrestrial snail species in Upper Egypt region has been identied by Assiut Governorate. All the species recorded belong to order: Pulmo-nata from eight families   (Ramzy, 2009). Keeping in view the signicance of gastropods in agricultural elds, the present study was undertaken for the identication of terrestrial snail species in Sohag Governorate, Egypt.   MATERIALS AND METHODS   The present study was carried out for survey and identication for random land snail in 11 districts, i.e.  (Tema, Tahta, Gehyena, El - Maragha, Saqultah, Sohag, Akhmim, El - Monshah, Gerga,     A    C    C    E    P    T    E    D    M    A    N    U    S    C    R    I    P    T  46   districts).   In the past years were land snails distributed in North Delta, where suitable climatic conditions (temperature - humidity - plant cover) and with climate change began to distribute in the gover-norates of southern Egypt recorded an in (Giza, BeniSuef, Minia, Assiut). In this study, land snails were recorded in Sohag for a second time more widespread and may be that this pest moved to these governorates with transportation, passengers from places spread these new places and happened to her adaptation and after have transferred from infestation regions so, have adapted under weather factors of new region also, several factors e.g., the presence of more preferable food, shelter, intra - specic competition, fecundity increasing, several hosts or habi-tat in the new ecosystems. This nding is in agreement with El - Okda (1979) recorded individuals of E. vermiculata  at Shatby and SediBechr districts, Alexanderia. While, M. obstructa  was recorded in Behera (El - Deeb et al ., 1999). Metwally et al . (2002) recorded six terrestrial snails include  M. cartusiana , E. vermicula-ta , C. acuta , O. alliarus ; the slugs, L. avus  and Deroceras reticula-tum  on different crops at 23 localities representing 10 districts at Monoa and Gharbia Governorates.   E. vermiculata  and M. obstructa  were recorded in the coastal area of the Nile Delta by El - Deeb et al . (1996 )and (2003) measured altered earthly snails on the eld crops, vegetables, ornamental plants and the orchards at different Governorates of Egypt. Re-sults showed that M. cartusiana , E. vermiculata , C. acuta , Cepaea nemoralis , Oxychilus aliavus  and Helicella  sp. were recorded on different host plants in Demietta Governorate while M. cartusiana , E. vermiculata , C. acuta , C. nemoralis and  S. putris were found in Dakahlia Governorate. However, E. vermiculata , C. nemoralis and  S. putris were common species in Kafr El - Sheik Governorate . While, M. obstructa  was recorded in Kafr El - Sheikh (Gabr et al ., 2006) and in Ismailia Governorate (Shoieb, 2008).   Ramzy (2009) surveyed nine land snail species in Assiut Gover-norate namely, E. vermiculata , M. obstructa , O. elegans , Vallonia pulechella , T. pisana , Vitrea pygmaea , Helicodiscus singleyanus inermis , Pupoides coenopictus  and Cecilioides acicula . The rst three species are accessory species while the accidental species include the other six snail species. In addition, O. elegans , V. pygmaea , P. coenopictus  and C. acicula  were recorded for the rst time in Egypt. Abo - El - Naser (2013) found that four terrestrial snails include three land snails and slugs were found in the main investigated sites in Assiut Governorate. The three land snail Abd El - Aleem Saad Soliman Desoky    /   Arch. Agr. Environ. Sci., 3(1): 45 - 48 (2018)   El - Balyana, and Dar El - Salam) at Sohag Governorate, Egypt. Samples were collected from 5 different locations in each district during 2016/2017 season. Monthly samples were taken from winter and summer crops (areas were cultivated with the field crops such as wheat, Egyptian clover, and vegetables crops. The other, was cultivated with fruit and ornamental trees). Snails collected from each sample were drowned overnight in water to facilities extension of the foot from the shell in any snails collected live. Snails were considered to have been alive at collection when the foot extended from the shell during drowning. Snails from each host plant in each surveyed areas were transferred in muslin cloth bags to the laboratory and identied according to the keys given by Smith and Kershaw (1979) and Godan (1983). After 24 hours, the water was decant- ed and replaced with 70% ethanol for preservation. The snails with complete soft parts were identied. To morphology study of the collected shell of the snail species respectively, shell was prudently washed and the visceral mass was removed according to the method of Frandsen (1983). After that, the shell of each species was photo graphed. The following references, beside others cited in the text, were used in the documentation of the collected snails: Pilsbry (1948); Horst (1958); Cameron and Radfern (1976); Godan (1983); Dindal (1990); Neubert (1998); Ibrahim et al . (1999); Barker (2001); Genena (2003); Yildirim (2004) Ramzy (2009).   RESULTS AND DISCUSSION   Mollusca are the second largest phylum of the animal kingdom, forming a major part of the world fauna. The gastropoda is the only class of mollusks which have successfully invaded land. They are one of the most diverse groups of animals, both in shape and habit. Amongst the gastropods, land snails (sub class: Pulmonata) are one of the maximum frequent with almost 35.000 described species of the world.   Data in Table (1), the terrestrial snail species were identied in many different sites at Sohag Governorate, during the study period 2016 - 2017 seasons. Through the table, the results showed the identication of two lands and their distribution was as follows Monacha obstracta  was recorded in the following areas (Tema, Tahta, Gerga, El - Balyana and DarEl - Salam districts) . While the Eobania vermiculata  was recorded in the following areas (Tema, Tahta, Saqultah, El - Maragha, Akhmim (Sohag, S.N.   Crops   Sites (districts)   Monacha obstracta   Eobania vermiculata   1   Egyptian clover   Wheat   Orchards   Ornamental trees   Vegetables   etc…,   Tema   +   +   2   Tahta   +   +   3   Gehyena  - - 4   Saqultah  - +   5   El - Maragha  - +   6   Akhmim  - +   7   Sohag  - +   8   El - Monshah  - - 9   Gerga   +  - 10   El - Balyana   +  - 11   DarEl - Salam   +  - Table 1. Survey of land snails collected from different districts in Sohag Governorate, Egypt, during 2016 - 2017.   + Found; -  Unfound    47   species are Monacha obstructa  (Montagu); Eobania vermiculata  (Muller) and Oxyloma elegans  (Risso) while a slug is Limax avus  (Muller). All terrestrial snails,  M. obstructa , E. vermiculata , O. elegans  and L. avus were recorded in the Exp. Farm, Fac. Agric., Assiut Univ., while M. obstructa  was recorded only in El - Wasta in Assiut Governorate, during the investigation period. L. avus  was recorded for the rst time in Assiut Governorate. These results can be used for future studies as follows: future work plan in an effective strategy for the implementation of snail’s management programs at varying environmental regulations in Egypt. Desoky et al . (2015) the results showed that found rst record and identied of two land snail species in Sohag Gover-norate. They are as follows Monacha obstracta and  Eobania vermiculata.   Conclusion   The present study concluded the occurrence of two species of land snails, Monacha obstracta  (Montagu) and Eobania vermicula-ta  (Muller) in the Sohag Governorate, Egypt. It was also noted that the spread of land snails was increased from previous peri-ods. The results also indicated that land snails were recorded in Sohag for a second time more widespread and may be that this pest moved to these governorates with transportation, passen-gers from places spread these new places and happened to her adaptation and after have transferred from infestation regions so, have adapted under weather factors of new region also, sev-eral factors e.g., the presence of more preferable food, shelter, intra - specic competition, fecundity increasing, several hosts or habitat in the new ecosystems. Therefore, the present investi-gation provides an interesting development plan for the effec-tive strategy for land snail’s management program in agro eco-systems in the Upper region of Egypt.   Open Access:  This is open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the srcinal author(s) and the source are credited.   REFERENCES   Abo - El - Naser, H.A.K.
