The study of the chemical and physical factors that induce egg-laying is important for understanding mosquitoes' ecology. These substances may also help assess and control mosquito populations. With this in mind, we have highlighted the attractiveness of Culex pipiens gravid females concerning the containers' color and surface, which has enabled us to show that females of this species are always attracted to large containers of yellow. The ethological tests were made with four biopesticides on the attractiveness of C. pipiens females. It has been observed that the highest densities of the eggs are deposited in the container which contains the biopesticides extracts compared to that which includes the spring water with a significant difference between the two environments (p: 1.00). This choice is due to the presence of odorous molecules which attract the mosquito.
The study aims to identify the third instar larvae of fly species (Order : Diptera) feeding on carcasses (Fishes and Rabbits). Two families (Calliphoridae and Sarcophagidae), were recorded with highest rate in Calliphoridae species. The following species had been registered in accordance with their prevalence respectively; Calliphora vicina Rob.-Desvoidy, Chrysomya albiceps (Wiedmann), Chrysomy megacephala (Fabricius), Sarcophaga sp. and Lucilia sericata (Meigen). The highest rate has been registered Calliphora vicina during February, November, December and January at rate 100%, the larvae of this fly have not been observed during July, August, September and October. The highest rate of Ch

Show MoreThe isolates of Staphylococcus aureus were isolated from patients with various infections in hospitals, the isolates were identified and accurately diagnosed by phenotypic examination and biochemical tests, as well Vitek-2, and then genetic detection and diagnosis of many of the pathogenic factors associated with Staphylococcus aureus using conventional polymerase chain reaction (PCR) and testing for association by antibiotic resistance and production of some toxins by Staphylococcus aureus. After performing analysis of statistical, it was set up that the correlation coefficient of the PCR technique using virulence genes, sensitivity test to antibiotics and other virulence factors were significant at p < 0.05, but was insignificant with the

Objective: The current study was aimed to detect the specific bacteria and predisposing factors that predisposed for the bacterial keratitis.
Material and methods: Retrospective study of the hospital records of 40 patients who were diagnosed as bacterial keratitis and treated at the Ophthalmology in-patient department of at Ibn Al- haithum Teaching Hospital from May 2015 to December 2015.Patients who don’t have corneal scraping, or culture and sensitivity findings
This research includes a study of the effect of four temperatures (25, 30, 35, 40m◦) with relative humidity 65% on some biological aspects of the Bean beetle Acanthoselides obtectus on the Bean seeds under laboratory conditions. The results showed that the effect of different temperatures is clear on biological of Bean beetle. Differed period necessary for the growth and development of each stage of the insect in different temperatures . The results of statically analysis showed a significant difference in the life cycle when all temperatures except the period between temperature 35 and 40m◦ , respectively. Where the average of those period, 60.75, 35.5, 20.34 and 19.27 days and also different temperatures significant effects is clea

The Oligocene-Miocene-succussion in western Iraq was selected as a case study, represented by the reefal limestone facies of the Anah Formation (Late Oligocene) deposited in reef-back reef environments, dolomitic limestone of the Euphrates Formation (Early Miocene) deposited in open sea environments, and gypsiferous marly limestone of the Fatha Formation (Middle Miocene) deposited in a lagoonal environment. The content of the rare earth elements (REEs) (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Ho, Tm, Yb, Lu, and Y) in reef facies appear to be much lower than of those in the non-reef facies. The open sea facies have a low content of REEs due to bein

Show MoreIn this paper, we attempt to predict the depositional environments with associated lithofacies of the main reservoir of the late Cretaceous Mishrif carbonate Formation, depending on the analysis of the created seismic isopach map by integrating seismic and well data. The isopach map was created from a 3D-seismic reflection survey carried out at the Dujaila oil field in southeastern Iraq, which is of an area of 602.26 Km2, and integrated with the data of the two explored wells. Based on the interpretation of the seismic isopach map, the diagram of the 3D-depositional environment model of Mishrif Formation was constructed. It showed three distinguished depositional environments, which were graduated from a back reef lithofacies of a shallo

Batch esterification of oleic acid was carried out at operating conditions; temperature from 40 to 70 °C, ethanol to oleic acid molar ratio from 1/1 to 6/1, H2SO4 as the catalyst 1 and 5% wt of oleic acid, reaction time up to 180 min. The optimum conditions for the esterification reaction were molar ratio of ethanol/oleic acid 6/1, 5%wt H2SO4 relative to oleic acid, 70 °C, 90 min and conversion of oleic 0.92. The activation energy for the suggested model was 26625 J/mole for forward reaction and 42189 J/mole for equilibrium constant. The obtained results s
