Effect of different compounds against some principle calcium precipitation parameters in shell was studied on two terrestrial snails, Eobania vermiculata and Monacha obstructa. The tested compounds were Newmyl (the recommended compound), Lambada, Actra as synthetic compound, Tracer (bioinsecticide) and Tannic acid (natural product). Animals of each species were treated with LC50 of each compound using contact technique. The calcium precipitation parameters (Alkaline phosphatase (ALP), Acid phosphatase (ACP), Total protein (TP), Total lipid (TL) and cholesterol) were measured after one, three and seven days post treatment.
Results showed that all tested compounds caused vacillated effects for the two snail species. Tannic acid and tracer were the most effective compounds on the all parameters in both species. While the recommended compound (newmyl) came in the last rank in the most of parameters. E. vermiculata was more susceptible to tannic acid than M. obstructa for ALP, ACP enzymes, total protein and cholesterol, while both species had the same response to total lipid. The fluctuation effects of tested biochemical parameters may be due to damage of cells under the impact of treatment with compounds.

Mites are part of important functional groups inhabiting arboreal parts of plants and soil food webs. Recognizing these mites and understanding their function in the ecosystem as well as when they are active is essential to understand their roles. The present work studied the abundance and diversity of mites associated with date palm, olive and citrus trees in Sakaka, Kingdom of Saudi Arabia during winter and spring seasons (December 2013 to May 2014).The recorded species associated with date palm, olive and citrus trees are classified according to the type of nutrition into three trophic groups: phytophagous, predaceous and miscellaneous mites. In total, 12 families, 13 genera and 13 mite species belonging to the four sub-orders Actinedida, Acaridida, Oribatida and Gamasida were recorded. The phytophagous mites were numerically dominant of three species belonging to two families. Whereas five species are predaceous mites belonging to five families. Moreover, the miscellaneous five species belonging to five families. Results obtained from this study revealed data about species recorded for the first time in Sakaka, Kingdom of Saudi Arabia where there is a need for such information to support future environmental programs in integrated pest management to attain good and healthy agricultural product.

Coprological samples of captive mugger Crocodiles (Crocodylus palustris) were randomly collected (102 Nos) from Snake Park, Guindy (36 Nos), Arignar Anna Zoological Park, Vandalur (44 Nos) and Amaravathy Crocodile farm (22 Nos) and screened for evidence of parasitic fauna using fecal sedimentation technique. Parasitic fauna evidenced trematode egg, Renifers which were predominant in Snake Park, Guindy and Amaravathy Crocodile farm and nematode eggs, Dujardinascaris sp. in samples from Arignar Anna Zoological Park, Vandalur. Among the study, Dujardinascaris sp. was predominant and mixed infections of Renifers and Ophiotaenia sp. were limited. However Polydelphis sp. was observed only in Amaravathy farm. Renifers and Dujardinascaris sp. were found in mugger crocodiles from all these three locations. No ectoparasites were encountered in mugger crocodiles during this study. Snake Park, Guindy and Amaravathy Crocodile farm had the habit of feeding fishes to this reptile encountered the presence of trematode and cestode eggs in these areas. Captivity provides the condition in such a way that ectoparasites could not be ruled out in this study unlike free-ranging habitat.

Like all other decapods, the grapsid crab, Metopograpsus messor has mouth parts composed of six pairs of modified appendages. The present study revealed the structural significance of this complexity and the feeding habits of this species. Scanning electron microscope was used for examination of the mouth parts of the specimens collected from two different habitats. No differences were found neither in the structure of mouth parts nor in food analyses. The feeding habits showed that M. messor is opportunistic omnivore feeding on a wide variety of benthic organisms including algae, epifaunal animals as well as dead fish and other decayed animals in addition to higher plants particularly decomposed sea grass leaves and mangrove.

Background: Technology advancement in the agricultural production which prompted the use of herbicides to control weeds is found to be potentially harmful to the environment and human health.
Method: lethal and sub-lethal effect of glyphosate on some biochemical parameters and growth responses of African catfish, Clarias gariepinus were investigated using static renewal bioassays and continuous aeration for a period of 96 h and 28 days using varying concentrations (20.0 mg/l, 30.0 mg/l, 40.0 mg/l, 50.0 mg/l and 60.0 mg/l) and (1.0 mg/l, 2.0mg/l, 3.0mg/l, 4.0mg/l and 5.0mg/l) respectively. At the end of the experiments, the fish were sacrificed and the blood samples were collected. The gill and liver of the fish were removed for biochemical bioassay.
Result: During the exposure period, the fish showed different abnormal behaviours such as restlessness, loss of balance, respiratory distress, grouping together, darting movements, and loss of equilibrium, mucous secretion and erratic swimming. Compared with the control, the result showed a significant increase (P < 0.05) in the activities of alanine aminotransferase (ALT), and aspartate aminotransferase (AST), superoxide dismutase (SOD) and lactate dehydrogenase (LDH) in the gill, liver and blood of Clarias gariepinus exposed to glyphosate for 96 h while the activities of enzymes ALT, and AST in both the blood and the gill of fish exposed to glyphosate for 28 dsys, except in liver where it showed a significant reduction. However the values of SOD and LDH showed significant increase in the blood with a noticeable decrease in both the gill and liver of fish. Growth rate was insignificantly different (p˃0.05) as the concentration increased compared to the control experiment. The highest percentage weight gain (12%) was observed in the control, while the lowest percentage weight gain (7%) was observed in the highest concentration. The specific growth rate of the fish reduced (p˃0.05) insignificantly as the concentration increased.
Conclusion: The study showed that sub-lethal concentrations of glyphosate are harmful to Clarias gariepinus. The implication of these results in rational exploitation and conservation of fishery resources and the public health risk of consuming glyphosate-exposed fish are highlighted.
