Evaluation of Some Attractive Materials in The Management of Red Palm Weevil, Rhynchophorus ferrugineus Oliv. (Coleoptera: Curculionidae by The Pheromone Lure-Food Based on Trapping System
The obtained results explained that the higher or lower density of red palm weevil populations in each of inspected date palm orchards is mainly attributed to the old and the numbers of growing date palm varieties in particular, Zaghloul and Sammany ones, the old and density of interplanted fruit trees within the rows of growing palms, the followed agrotechnical practices and the prevailing agroclimatic conditions, which all in combination more or less affect on the increased or decreased population density of developing weevils that correspond to the occurring infestation level and in sequence reflects on the rate of catch weevils. The calibrating delayed emergence of the insect pest during most months of the growing season was detected. The higher rates of catch weevils occurred during the periods of March-April, May-July and October-November in both investigated orchards. The determined efficiency of used aggregation pheromone lure with or without the tested chemical material or food baits in the tested traps proved that the utmost efficient one was the food baited pheromone trap with treacle + yeast + tap water, with total catch weevils reached to 279 and 565 insects; resembled 26.1 and 31.6% of the grand total of captured adults per year in 1st & 2nd orchards, respectively. The nextly ranked pheromone traps were those supplied by date fruits + yeast or ethyl acetate in respect, and/or the aggregation pheromone alone. The supplemented traps with diluted treacle + yeast, date fruits + yeast and ethyl acetate alone were to more extent unefficient and gave rather decreased rates of catch weevils. Moreover, the data showed that the same detected higher or lower efficieny of evaluated pheromone lure food based trapping system was proved also for the determined monthly periodic intervals of efficient captures all the year round and the calculated annual means of catch adults of both sexes in the inspectd orchards.

Storage Temperature and Storage Duration Affect Fruit and Oil Quality of Coratina, Manzanillo and Picual Olives
During 2008 and 2009 seasons, Coratina, Manzanillo and Picual olive fruits were stored at 5, 10 and 20˚C with 85 - 90 % relative humidity.All olive cvs were stored only for one week at 20˚C with the loss of fruit appearance. Coratina fruits were the most tolerant to chilling injury and no internal browning was observed in fruit flesh of all cvs during the storage period. Storage temperature had significant effect on fruit weight loss where the stored fruits at 10˚C lost more than 3 folds of those stored at 5˚C. By the progress of the storage period, fruit weight loss increased while the moisture values declined and the stored fruits at 5˚C had significantly higher moisture content. Coratina olives significantly contained the highest oil content (26.81 and 28.10 %) followed by Picual (25.21 and 26.44 %) then Manzanillo fruits (24.25 and 25.55 %). Oil content decreased significantly with increasing the storage temperature and time. Palmitic, arachidic, oleic, palmitoleic and linoleic fatty acids were not affected by the storage temperature. Myristic fatty acid increased in Coratina fruits stored at 10˚C. Stearic acid values of Coratina and Manzanillo declined by the end of the storage period while that of Picual increased. Myristic, palmitoleic and linoleic fatty acids increased with the progress of the storage period while arachidic and oleic fatty acids decreased. Linolenic acid content of Coratina fruits increased in the third week at 5 and 10˚C then decreased with the progress of the storage period. Coratina had the highest linolenic content at the third week while Manzanillo had the highest content after 4 weeks at 5˚C. There was no effect of the storage temperature or period on fruit lipids content but generally, the fruits that were stored at 20˚C contained lower values.

Effect of Seeding Rate and Ga3 Application on Hybrid Rice Seed Productivity under Seed Production Plots
Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station, Kafr El–Sheikh Governorate, Egypt, during the two successive summer seasons of 2007 and 2008.The field experiments were conducted to study the effect of seeding rate and GA3 doses in the hybrid rice seed production plots on growth characters, yield and its components of F1 hybrid rice plants. The material under this study included the parental lines IR 69625 A as (female line) and Giza 182 (restorer line) to produce the seeds of F1 hybrid rice (SK 2058 H). A split-plot design with three replication was used. The main plot was devoted to seeding rate of 20, 24and 28 kg seeds/ha, while the GA3 doses were assigned in the sub plots. Four doses of GA3 (BERLEX) 300, 350, 400 g/ha and a control treatment (spraying with water) in two spraying times. The results showed that, Plant height and flag leaf angle were highly significantly affected by the different doses of GA3 and different seeding rate. The female parent of the hybrid, SK 2058 H, had a wide variation for panicle exsertion. The hybrid seed yield was highly significantly affected by GA3 application. It was increased by using 300g GA3/ha, indicating the positive effect of application. The1000-grain weight was decreased with increasing the doses of GA3 while the application of high doses of GA3 increased the seed set percentage, but reduced the grain filling rate. The grain yield of the IR69625A was highly affected by the seeding rate and GA3 applications. Results also showed that using 20 or 24 kg seeds/ha from IR69625A and GA3 application by the rate of 350 g/ha may be the best combination for hybrid rice seed production. ased with the progress of the storage period. Coratina had the highest linolenic content at the third week while Manzanillo had the highest content after 4 weeks at 5˚C. There was no effect of the storage temperature or period on fruit lipids content but generally, the fruits that were stored at 20˚C contained lower values.

Effect of slow release fertilizers application on growth and chemical composition of some indoor plants
The present study was carried out during two successive seasons (2008 and 2009) at the Nursery of the Alexandria University, Somoha, Alexandria, Egypt to determined the optimum rate of application of two types of slow release fertilizers [Hydro complex (HC) and PG-Mix (PG)] on growth and chemical composition of some indoor plants (Dracaena marginata and Beaucarnea recuvata) growing in pot experiments. With respect to the Dracaena marginata experiment, it was found that applying 15 g/plant of HC at four-month intervals resulted in the highest significant values of plant height, leaf number/plant, leaf length and width, stem diameter, root volume and root dry weight. Moreover, applying the above mentioned treatment gave the highest significant values of leaf NPK contents, leaf total chlorophyll contents and total carbohydrates. Whereas, fertilizing the plants with PG at rate of application of 15 g/plant at four-month intervals resulted in the highest significant values of fresh and dry weights of leaves. On the other hand, the results indicated that there were no significant differences detected due to applying 15 g or 10 g/plant at four-month intervals of HC on leaf number/plant , leaf length and width, stem diameter, root dry weight, leaf phosphorus and total carbohydrates contents. Regarding the Beaucarnea recuvata experiment, the results indicated that fertilizing the plants with HC at rate of application of 15 g/plant at four-month intervals resulted in the highest significant values of leaf number/plant, leaf length and width, fresh and dry weights of leaves, stem length and stem diameter, root volume, as well as gave the highest significant values of leaf NPK contents and total carbohydrates. Whereas, fertilizing the plants with PG at rate of application of 15 g/plant at four-month intervals resulted in the highest significant values of total leaf chlorophyll contents. On the other hand, it was found that there were no significant differences detected due to applying either 15 or 10 g of PG on leaf number/plant, leaf length, stem length and diameter, root volume and leaf nitrogen and potassium contents. Whereas, applying with 10 g/plant of PG at four-month intervals resulted in the highest significant values of leaf total chlorophyll contents. The study recommends applying the slow release fertilizer Hydro complex at rate of application of 15 g/plant at four-month intervals to get the most quality of the characters study of Dracaena marginata and Beaucarnea recuvata plants grown in pots.

Evaluation of low Fat Ice Cream Influenced by Oat Flour Fiber Addition as a Milk Solid Replacer
The objective of thisstudy was planned to evaluate the possibility of using Oat flour as partially replacement of milk solid not fat at levels, 20, 40, 60 and 80 % of skim milk powder (SMP) comparing with control without oat fiber on the physical and rheological characteristics of low fat ice cream formula in relation to their sensory attributes. The obtained results are shown as following: a significant effect in pH and viscosity (p < 0.01) between the low fat levels and the among Oat flour treatment. Meltdown characteristics of low fat ice cream demonstrated a clear relationship between increased Oat flour replacement and improved melting properties. The fat levels and Oat flour replacement had a significant effect (p < 0.01) on the texture properties including: hardness, adhesiveness, gumminess, and chewiness. Organoleptic results of flavor, body and meltdown showed an improvement toward increasing Oat flour replacement comparing with control. Generally ice cream blends of 40 and 60% replacement ratio were the preferred mixes.

Effect of Detergent and Antibiotic Residuals on Proteolytic Activity of Plasmin on Beta Casein
Plasmin plays a significant role in cheese ripening and characteristics of dairy products. The antibiotic could be presented in milk as residuals from animal treated by antibiotic, while presence of detergent could be as residuals from cleaning of milking machines, tanks during transpirations, storage tanks and pasteurization equipments etc. The effect of detergents and antibiotic residuals on proteolytic action of plasmin on β-casein in model solution was determined by Urea-polyacrylamide gel electrophoresis. The results suggested that plasmin followed the proteolytic pathway on cow b-casein to produce g1, g2 and g3 as the degradation fragments. The proteolytic pathway has been affected by presence of sodium hydroxide and nitric acid, while was not affected by presence of antibiotic. The results also indicated that the presence of sodium hydrioxid increased the plasmin activity, while plasmin hydrolysate of B-casein slightly inhibited by nitric acid. The proteolytic activity of plasmin on b-casein was broader and higher at the end of incubation period, to yield low-sized fragments as evidenced with polyacrylamide gel electrophoresis. Increased plasmin activity by sodium hydroxide residual could affect cheese making characteristics such as the rennet coagulation time, curd strength, and curd syneresis, produce off-flavor and bitterness in cheese. Since the plasmin is heat stable enzyme, increasing its activity in UHT milk could case gelatoin and produce off-flavor and bitterness.

Effect of Putrescine, GA3, 2, 4-D, and Calcium on Extending Harvest Season of Navel Orange
The present study was conducted in 2007/2008 and 2008/2009 seasons in order to extend harvest season and maintain fruit quality for better marketability of Washington navel oranges growing in clay soil by preharvest foliar sprays (at color break stage) with GA3, 2,4-D, putrescine and calcium either alone or in combinations. Trees were harvested at mid- February (late in the season). All sprayed substances delayed fruit softening, peel ageing and fruit color break and decreased creasing and preharvest fruit drop. Also, fruit TSS, sugars and V.C. contents were increased. The treatments had positive influence on extending harvest season without any deterioration in fruit characteristics. In general, spraying the different substances in combinations gave better results, especially for putrescine and 2,4-D.

Measuring the Long Run Impact of Loans on Agricultural Gross Domestic Product in Saudi Arabia Using Co-integration and Error Correction Models
This study was designed to measure the impact of loans provided by the Government of Saudi Arabia on the total output of the agricultural sector during the time period 1971-2008 AD. The study relied on secondary data published and used modern methods of analysis of recent tests in the Co-integration Test and models of Error Correction Models (ECM), which reflects the dynamic relationship in the short term since the use of standard conventional methods of analysis may often leads to inaccurate results.
The results obtained that the degree of auto regression of the output of the agricultural sector gross capital of the loans in Saudi Arabia is the second differences of the variables. By studying the direction of causality between the two variables show that the GDP of the agricultural sector does not Granger cause capital formation for loans, while significant relationship was confirmed that the composition of capital for loans Granger cause the concept of levels of GDP of the agricultural sector and in conformity with reality in Saudi Arabia due to the support of the agricultural sector through the gross domestic product, which depend on the oil revenues. The co-integration equation explain the relationship between the total output of the agricultural sector and capital formation for the loans that the contribution of capital formation for the loans to a change in the gross agricultural output in the long run amounts to 69.3%, while the results show that the model error correction rate of growth of total agricultural sector output in the long short equals 7.9%.

Factors Associated With Level of Knowledge and Practices Among Rural Women Regarding Waste Usage and Environmental Conservation in Several Villages, Behaira Governorate
Research was conducted to study the level of knowledge and practices among rural women regarding the use of waste and conservation of the environment in the province of Behera and some of the some of its related factors. The study was based on form and personal interview for the collection of field data of the selected rural women sample which was composed of 260 in number. Then from the total recipients, 5% of the rural women with their husbands were randomly selected out of the eight villages of the four centers of the province of Behera, namely: Kafr El-Dawar, Abu Homous, Damanhur and Itay El-Baroud. frequency and table presentation, percentages, arithmetic mean and standard deviation, simple correlation coefficient ,were used to present and discuss results . The following are most important findings: 1. Level of knowledge of the rural women in the preservation of the environment showed that the largest proportion of rural women was from the middle-class section; it was in 45% proportion. Whereas the proportion of women with limited level of knowledge was 31.5% and with a high level of knowledge was 23.5% from the total number of women. 2. The majority of rural women (74.5%) belong to the categories of women with level of practices that are most harmful and produced medium damage to the environment. 3. There is a direct correlation between the level of knowledge related to the use of waste and conservation of the environment and the total educational attainment of the rural women and their husbands, the degree of urban cultural receptiveness, and the number of information sources. Whereas the relationships were not significant with the rest of the independent variables studied. 4. There is a correlation between the level of practices of rural women related to the use of waste and conservation of the environment and the total educational attainment that were studied together with their husbands, the degree of urban cultural receptiveness, and the number of sources of information. 5. The most important reasons that limit the ability of rural women, from their own point of view, to protect the environment is the lack of a healthy means to get rid of waste, the backward traditional methods of waste disposal, and the lack of knowledge about the correct methods of waste disposal.
