Specifically, this study established to assess the molluscicidal effects of crude juice of Citrus limon fruit and Citrus limon peel on the developmental stages of Eobania vermiculata (chocolate band snail) and Monacha cartusiana (glassy clover snail). These juices were used individually against the three, six and nine-month-old and adult of both snails in the laboratory and also applied against adult individuals of each snail species in the field for 21 days. Results showed that the juveniles three months old were more susceptible to C . limon fruit and C . limon peel juices than the other ages of both snails. Moreover, C . limon fruit juice was more effective on the two snail species at all ages than the juice of C . limon peel. The crude suspension of C . limon fruit and C . limon peel caused 73.33& 46.66% and 60 & 46.66% mortality of adult snails of E . vermiculata and M . cartusiana respectively after 14 days of the laboratory experiment. While in the field assay, they were recorded 70.39 & 62.30% and 62.08 & 55.79% reduction of both snail adult individuals consecutively after the same period of application (14 days). Therefore, E . vermiculata snails were more affected by the two suspensions than the snails of M . cartusiana under both laboratory and field conditions. C . limon is a promising potential organic substitute to chemical molluscicide with no harmful impacts on humans and the environment.","PeriodicalId":513213,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, B.

Barriers that restrict the movement of animals allow for geographic isolation. In the present study, to investigate the evolutionary forces driving the differentiation of the Cairo spiny mice, Acomys cahirinus , particularly as related to the biogeographical relationship between the Western and Eastern Deserts of Egypt, thirty-eight skulls of male specimens of the Cairo spiny mouse from four different regions of Egypt that were kept in Al-Azhar University Zoological Collection in Cairo, Egypt were examined. Five of these skulls came from Bahariya Oasis, seven from Dakhla Oasis, five from Helwan region, and twenty-one came from Eastern Desert. Based on sixteen absolute cranial and dental measurements and seventeen ratios used here, A. c. helmyi from Dakhla Oasis differ greatly from those from Bahariya Oasis ( A. c. cahirinus ), Helwan region ( A. c. cahirinus ), and Eastern Desert ( A. c. hunteri ) populations. There were many cranial and dental characteristics correlated with each other. Most of these characteristics are highly positively correlated with body mass, condyloincisive length, and mastoid width. Despite the presence of this natural ecological barrier (the Nile Delta and Valley), a great similarity was found between the Cairo spiny mouse populations from Bahariya Oasis (Western Desert) and from Eastern Desert, noting the great difference between the Cairo spiny mouse populations from Dakhla Oasis (Western Desert) from the other populations in the present study.","PeriodicalId":513213,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, B.
