Red palm weevil, Rhynchophorus ferrugineus (Oliver, 1790), Order; Coleoptera, Family; Curculionidae, is considered as the biggest threat facing date palm cultivators. The larva feed on trunk tender tissue and can cause palm death within 6-8 months after infection. Insect gut harbors a community of bacteria that lives in an endosymbiotic relationship with the insect and it is strongly evident that it plays a key role in insect life. Deciphering and identification of insect microbiota could lead to the development of new symbiotiont-based control approaches. In this work we studied the diversity of the endosymbiont bacterial community of red palm weevil larval midgut in Egypt, by using Denaturing Gradient Gel Electrophoresis (DGGE), based on 16S rRNA genes PCR amplification. We used three groups of field caught larva sampled from two different places; El-Badrashin and Agricultural Research Center (ARC) in Giza governorate, Egypt. DGGE profiling patterns has shown the relative prevalence of bacterial phylotypes  affiliated to family Firmicute; Leuconostoc lactis, Lactococcus lactis, Lactobacillus nagelli and bacterial phylotypes affiliated to family Actinobaceria; Cellulomonas cellasea, Bifidobacterium minimum, which suggest that they have a potential role in nutrition, physiology and immunomodulation of the insect.

The mycelial growth rate of three oyster mushroom strains namely Pleurotus erengii, P. ostreatus and P. florida was examined on six different agar media (malt extract, Potato dextrose, rose bengal, corn meal, czapek’s dox and waksman’s glucose agar media) to select the most suitable one. Effect of pH was also examined at different values (5.0, 5.5, 6.0, 6.5 and 7.0) on the selected medium. Results indicated that Malt extract agar medium was the most suitable one for mycelium growth of all the tested mushroom strains, being the highest (9 cm ) for P. erengii and P. ostreatus at pH 7 and 9 cm at pH 6 -6.5 for P. florida after 6 days of incubation. The mycelia growth of the tested oyster mushroom strains was also examined at different temperatures (15, 20, 25, 30 and 35ºC) and different levels of relative humidity (50, 65, 75, 85, 95 and 100 %) on malt extract agar medium. The highest mycelial growth rate was obtained at 25°C and relative humidity of 65% after 6 days of incubation for the three tested oyster mushrooms.

The study was designed to evaluate the effect of barley grain etiolated sprouts mixture with faba bean, Egyptian clover, wheat and rice hays to improve fodder value. Hays were used as media to etiolated sprouts of barley with three seeding densities (10, 20 and 30% w: w). Growing conditions of the system can produce between 12.8 to 38.38Kg of fresh fodder and 3.18 to 9.10Kg of dry fodder in 4 days from one kilogram of dry barley grains. The dry fodder per unit seed volume (Kg/Kg grain) was decreased with increasing seed density. Since hays were decreased but the nutrient content of the fodder, especially protein was increased. Barley etiolated sprouts improved quality of hays fodder from faba bean, Egyptian clover, rice and wheat crop. Carbohydrate lipid, protein and total energy content were increased with increasing barley-seeding density while crude fiber was decreased. In vitro dry matter digestibility (IVDMD) was decreased with decreasing seed density especially with rice hays (39.92) and increased with increasing seeding density especially with faba bean hays (74.77). Fiber fraction (Neutral detergent fiber NDF, Acid detergent fiber ADF, Acid detergent lignin ADL), cellulose and lignin percentage were decreased with increasing seeding density of barley, Relative feed value (RFV) was increased with increasing seed density for barley grown on faba bean, Egyptian clover, rice and wheat hays.                      The barley etiolated sprout production system obtained a good quality fresh forage in small area all year around and low cost estimated per ton DM; total digestible nutrients (TDN) and crude protein (CP) compared with hydroponic barely green sprouts. Therefore, the system can recommended as cheap energy (TDN) and protein (CP). In addition, the system saving agricultural lands and partially water consumption for strategy crop production as wheat and corn since its fodder products can produced and grown in small dark area during absence of natural forage.

Inflation is meant the overall and continuing rise in prices by the impact of internal or external variables, produced by excess demand about supply capacity. Problem of the study: The Egyptian economy has a decline in overall economic indicators, most importantly is the overall growth rate, compared with a rise in inflation, poverty, unemployment, the low production and the continuing deficit in the trade balance, and in general budget, which are negative indicators for the Egyptian economy. Therefore, the study is trying to explain and study the problem of inflation, its direct and indirect effects on overall growth rates in the Egyptian economy. Research Objectives: Identify the reality of growth rate in the Egyptian economy; identify what are inflation types and methods of measurement, measuring interaction relationships between both of inflation rates and growth rates in the Egyptian economy, determine factors afficting of both inflation and growth rates in Egypt, to work on indirect effect in these phenomena by afficting on those factors.   Results and recommendations   1-To study the effect of the most important variables of affected GDP at current and real prices in Egypt during the period (2003-2014): It turns out that study variables give effects on growth rate in real GDP at real prices consistent with economic logic, on the contrary effects of the growth rate of GDP at current prices. 2- Study interrelationships between the local annual growth rate at real and current prices and the annual inflation rate in Egypt during the period (2003-2014): It was concluded that data will be relied on real growth rate of GDP in its relations with inflation, where it is more logical from the economic point of view than the results of the GDP growth rate of GDP at current prices. 3- The relation between the inflation rate and growth rate GDP in real terms is negatively slope. 4- The results of the current economic model show that: The most important factors affecting in inflation rate and real growth rate in GDP are: First: Annual inflation rate in consumer prices (X2), it has a negative significant statistically effect for both of annual growth rate of GDP at real prices% (X6), net cash reserve (X8), and the balance of current transactions and transfers (X13). And positive significant statistically effect for both of exchange rate of the dollar declared by the Central Bank (X10), and and the total surplus (deficit) (X21). Second: Annual growth rate of GDP at real prices% (X6), it has a negative effect from, annual inflation rate in consumer prices (X2), and the exchange rate of the dollar announced by the Central Bank (X10), while the effect was statistically significant positive for both of, net cash reserve (X8), and the total surplus (deficit) (X21). 5- Best method to forcast the main variables under study of inflation rate and the real growth rate of GDP is the use of the simutianeous equation model it takes into consideration all external variables affecting the internal variables under study. It was reached by forcasting both of the Inflation rates and real GDP growth rates, that the policies followed by floating exchange rate, which requires an impact on all variables to the hoped results of the floating of the Egyptian pound.   Therefore research recommends: to re-enter the Central Bank for determining the exchange rate of the Egyptian pound against other currencies, not directly to the currency exchange rate, but by indirect intervention through supply and demand control of the currency in Egyptian market against other currencies, by intervening in the market by selling and buying direct from banks, in addition to moving external variables affecting both inflation and real growth rates in Egypt to able to reach the resalts of simulitanuos equation model which takes into account all external variables related to the study variables.

Food is a vital necessity for humans. Providing food in quantity and quality is not only necessary to meet biological needs or to achieve a decent standard of living, it is also an essential step for civilizational leapfrogging. The results indicate that the total Egyptian fish production increased at a statistically significant annual rate estimated at 57.2 thousand tons per year. The quantity of fish consumption in Egypt increases annually at a statistical average of 62 thousand tons per year. At a statistically significant annual rate of 0.44 kg per year, and the fish gap shows its fluctuation between the rise and fall during the period considered and the most important results of the consumer spending functions of the animal protein group in Egypt and the expenditure elasticities of these groups according to the economic and social factors that the expenditure on the animal protein group is generally higher. The results also showed the effect of both urban and rural on the consumption patterns of the animal protein group. The results indicate that the consumption expenditure patterns on the animal protein group in both rural and urban areas will be affected. In addition, the expenditure on urban animal protein will decrease in general from 2013 to 2015, countryside. The results showed that the household expenditure in Egypt has different and significant differences according to the annual expenditure categories of the private household, income, expenditure and consumption 2012-2013-2015-2016.

A 7x7 half diallel cross along with their parental wheat cultivars were evaluated under two sowing dates (19th Nov. and 17th Dec.).The results revealed that mean squares due to sowing dates, genotypes and genotypes x sowing dates interaction were significant for most of the studied traits. Delaying sowing date to Dec. reduced all studied characters compared to the normal sowing date except electrolyte leakage which increased by delaying sowing date. Heterosis over better parents showed that, the best hybrids under stress condition were Misr 2 X Giza 168 and Sids 1 X Giza 168   for grain yield / plant and some of other studied traits.  General and specific combining ability mean squares indicated the importance of both additive and non-additive gene effects in the inheritance of the studied traits with few exceptions. However, the additive effect was more important than the non-additive effects in the inheritance of days to 50% heading, plant height, No. of spikes/ plant,No. of kernels / spike and 1000-kernel weight while, the non-additive effects were more important than the additive effects in the inheritance of electrolyte leakage and flag leaf area. The best general combiner parents for grain yield / plant and some of other studied traits were Gemmeiza 11 and Giza 168under stress condition. The best hybrids for SCA effects were Sakha 93 X Sids 1, Gemmeiza 11 X Giza 168, Misr 2 X Giza 168 and Sids 1 X Giza 168 under stress condition for grain yield / plant and some of other studied traits. The crosses Gemmeiza 11 X Giza 168   (HSI 0.36), Gemmeiza 7 X Giza 168   (HSI 0.58) and Sakha 93 X Giza 168   (HSI 0.60) have recorded the lowest values of heat susceptibility index (HSI), indicating their tolerance to heat stress (late sowing date).

This study was carried out to investigate the effect of saline water irrigation at 2000, 4000, 6000, 8000 and 10000 ppm by using a mixture of two salts (sodium chloride: calcium chloride, 2:1, w/w)  in addition to tap water  as control and foliar sprayings of Salicylic acid (SA) at 100, 200 and 300 ppm in addition to tap water as control on growth, flowering and chemical composition of pot marigold plants in the two successive seasons of 2014/2015 and 2015/2016 in the Faculty of Agriculture, Ain Shams University, Qalyubia Governorate, Egypt. Results revealed that all tested foliar applications of SA increased all vegetative growth characteristics (plant height, number of leaves /plant, leaf area, number of branches/plant, diameter of stem, fresh and dry weights of vegetative growth and roots, and roots volume), and flowering attributes (number of inflorescences/plant, diameter of inflorescence, fresh and dry weights of inflorescences). While, saline water irrigation decreased growth, flowering parameters, chlorophyll, carotene contents in flowers and some minerals contents of the vegetative growth, i.e. nitrogen, phosphorus and potassium percentages. However, saline water irrigation increased proline and some mineral contents, i.e. calcium, sodium and chloride percentages of the vegetative growth. In most cases, under the same saline water irrigation conditions spraying SA at 100 and 200 ppm concentrations alleviated the salinity effect on the plants, enhanced the plant growth and increased the flowering parameters. The most effective treatments which enhance growth, flowering parameters, chlorophyll content, carotene contents in flowers, proline and mineral contents were found to be 100 and 200 ppm SA spraying under nonsaline conditions.

Balanced nutrition plays an important role in preventing chronic diseases such as cardiovascular disease. The quality of fats and carbohydrates also have a protective effect compared to the consumption amount. The consumption of diets high in polyunsaturated fats, omega-3 fatty acids, vegetables, fruits, whole grains, nuts, and low in refined grains, processed red meat and sugary drinks, reduce cardiovascular disease. The aim of this research is to monitor the personal, nutritional, healthy and habitual risk factors related to cardiovascular diseases of female employees and students at King Faisal University in Al-Ahssa Province, Eastern Saudi Arabia. The descriptive analytical approach was used. Data were collected by distributing two forms included general questions about female employees and students (eg, age, socioeconomic status and place of residence), The two questionnaires were accompanied by two lists, the first included a range of risk factors for cardiovascular disease, and the other included 16 nutritional practice related to cardiovascular disease. Also some anthropometric measurements of the sample were recorded. The sample included 75 female employees and 425 female students volunteering in the study, from three colleges in the university, and data were statistical analyzed. The results showed that the level of nutritional practices associated with cardiovascular disease is "average" for most of the sample of the study, Which is better among university female employees compared to female students (P = 0.000). The mean number of risk factors for cardiovascular disease was 4.03 and 2.77, respectively. The risk factors for most of university's employees included age factor (82.7%), psychological stress (80%), overweight and obesity (69.3%) and the classification of waist circumference was a risk factor and high risk (66.7%). The risk factors for students were psychological stress and the presence of one smoker or more in the family. Based on the results, the study recommends that the university students and employees should carry on following good nutritional, healthy and habitual practices that reduce the risk factors for cardiovascular disease, as well as modify the bad nutritional practices with good ones. The study also recommends the university administration to provide nutrition education programs. This will increase the awareness of students and employees of the university about the importance of balance nutrition and encourage them to adopt good nutritional Habits and health lifestyle.

A total number of 120 nulliparous APRI and Baladi Black does (60 does for each breed) were mated at 5 months of age at the beginning of the breeding season (during September) to study the effect of re-mating interval after the first parturition on the litter parameters, milk yield per day and reproduction traits. All does were randomly divided into three equal groups according to reproductive rhythm: The 1st group: post partum (PP), the 2nd group: 11 days after parturition (P11), and the 3rd group: Post weaning (PW) .The body weight of P11 does were slightly higher than that of PP or PW groups. The re- mating interval groups during second parity had significant (P<0.05) effects on litter traits at weaning. Litter size and Litter weight at weaning age in PW group were higher significantly (P<0.05) than those in PP and P11 groups. Litter weight at 21 days of age in PW and P11 groups were higher significantly (P<0.05) than those in PP group. The PW group had significant higher litter size at weaning than those in PP group. Daily milk yield (DMY) after second parity was affected significantly by re-mating interval groups in the third and fourth week of suckling period. GL in PP group was higher significantly (P<0.05) comparing with P11 or PW groups. The values of litter size and weight traits were better for APRI does comparing with BB except litter weight at 21 days. The difference in results between the two breeds in daily milk yield showed generally higher trend of daily milk yield for APRI over BB. The Kindling interval and the gestation period were significantly (P<0.05) affected by interaction of re-mating interval group and breed. In conclusion, applying a lengthened period after the first kindling (by more than 10 days or after weaning) had a favorable effect on the does’ production.

The present study aimed to justify the effects of restricted feeding periods during last month of pregnancy and initiation of lactation on growth rate of Maghrebi she-camel and their offsprings. Sixteen pregnant she- camels with an average body weight 512.74 kg were divided randomly into three groups. The first group (G1) was fed 100% of their daily requirements concentrates. The second group (G2) was offered 75% of their daily requirement of concentrates after delivery for one month, while the third group (G3) was fed on 75% of  their daily of concentrate requirements for two months (one month pre and another one post-partum). New born calves were divided after one month of lactation to four groups as following; calves born  G1 dams were divided randomly to two subgroups. The first one (G11) suckled their dams naturally, while the other (G12) was artificial reared on a milk mixture (50% natural camel milk and 50% cattle milk replacer). Calves born to G2 and G3 dams were artificial reared on a mixture 50% natural camel milk and 50% cattle milk replacer. Results obtained showed that she-camels of G1 gained insignificant more live body weight than that of G3 during the pre-calving period 49.09 vs. 42.05 kg, respectively. There were insignificant differences among the 3 groups in calves birth weight 30.44, 32.8 and 29.73 kg, respectively. During lactation period, she-camels of G1 produced insignificantly more daily milk in compare with the corresponding she-camels of G2 and G3 (3.78 liter vs. 3.32 and 3.4 liter/ animal), respectively. She-camel of G3 lost significantly (P˂0.05) more LBW from the beginning of the experiment to the end of the study in compare with both of G1 and G2 she-camels. Calves of one month of age and born to G1 dams indicate faster (P˂0.05) daily gain (0.326 kg / h/ day) than those to both of G2 and G3 dams. Three months old age calves of different groups, indicated nearly similar growth, regardless of their dams feed restriction and type of calves rearing (natural vs. artificial). Data obtained showed also that neither she-camels feed restriction practice nor type of calves rearing have any significant effect on either calves daily gain or dams final LBW after 3 months of treatments.
