“…Morphologically, C. barbara can be distinguished from C. conoidea by shell heightless than 2x width, whorls more flattened, and sutures shallow with C. barbara, while in other species shell conical, whorls convex and shallow sutures (Ali and Ramdane, 2020), which represent a molecular difference from the results of the current study. In Clade (E), Rumina decollata (Fig.…”

Land snail identification researches in Iraq is limited. In Erbil-Iraq, a study was carried out to explore the identification of various land snails. In earlier studies, most species determination was based on shell morphology, anatomy of genitalia, and mantle color, these criteria are continuously applied to describe new species/new records. Species of similar morphology have ambiguous identities, especially juvenile specimens, due to the great level of morphological variation observed in some snail species. Five species of land snails belong to four families were found in different locations of Erbil City, Iraq, during November 2020 to April 2021, when average temperature was arranged (4-25 C°). Morphology and Cytochrome c oxidase subunit I (COI) gene were used to identify specimens, Rumina decollate (Linnaeus, 1758), found for the first time in Iraq. In addition to four species: Eobania vermiculata (Müller, 1774), Cornu aspersum (Müller, 1774), Cochlicella barbara (Linnaeus, 1758) and Polygyra cereolus (Megerle von Mühlfeldt, 1818) were previously registered in Iraq and have never been recorded in Erbil City, Kurdistan Region, Iraq. This study highlights the impotence of genetic analyses along with morphological analyses in identification of species. This finding suggests, for precise evaluation of species diversity, molecular tools should be included in future biodiversity researches.

This study reports the first occurrence of the terrestrial snail Cochlicella acuta in Assiut governorate, Upper Egypt during a survey carried out between March 2018 and February 2020. The conical snail, Cochlicella acuta is a species of terrestrial snails in the family Geomitridae. The individuals of C. acuta snail were found in two localities, Al-Muallimeen nursery, Assiut district and orchard fruits, Sedfa district at Assiut governorate, Upper Egypt. The specimens found were collected and transferred to the laboratory for examination to provide some data about the morphological features of these specimens and photographs to confirm the identification of this species. The snails were found on some ornamental plants, fruit trees and Egyptian clover were observed during the study period. Thus, this study contributes some information about the distribution and occurrence of this species on various plants in the studied areas of Assiut governorate, Upper Egypt was provided.

“…In Egypt, terrestrial gastropods have emerged as the most crucial agricultural pests, leading to substantial crop damage across different regions (Ali-Asmaa, 2014;El-Deeb et al, 1999;Ibrahim, 2017;Mahrous et al, 2002). Furthermore, Ali and Ramadane (2020) reported that clover land snails (Monacha sp. ), are a widely recognized species in Egypt, found in all governorates and observed on various crops and trees.…”

Land snails (Monacha obstructa) are commonly found in a variety of plant species, making them an important target for this study. Therefore, the opjective of this study is to compare eleven plant extracts and select the most efficient one to evaluate the acute toxicity of their extracts using the contact method against Monacha obstructa. The findings revealed that the plant extracts with the highest effectiveness against land snails were chinaberry (Melia azedarach), apple of Sodom (Calotropis procera), Nerium (Nerium oleander), and Basil (Ocimum basilicum) leaf extract. Consequently, the results indicated that the aqueous extracts from the leaves of M. azedarach exhibited high toxicity, with an LC50 value of 11.88 mg/L and a 100% mortality rate. Following that, C. procera leaves had an LC50 value of 16.82 mg/L and a mortality rate of 70.61%. The aqueous extracts from N. oleander (flowers and leaves) displayed a moderate mortality rate of 58.06% and 56.96% with LC50 values of 20.46 mg/L and 20.85 mg/L, respectively. The decoction of the leaves of the plants with O. basilicum leaf extract had the lowest death rate for individuals after 24 h which was 45.90%, and the toxicity rate for land snails was recorded at 25.88 mg/L. However, the rate of death of treated snails were decreased compared to that of control ones. These findings suggest the potential recommendation of utilizing a decoction of the extracted plants as an alternative to expensive and environmentally harmful pesticides for controlling clover snails.
