Despite of the great healthy advantages of ol-ive crop whereas it protects human from arterio-sclerosis, heart diseases and blood cycle diseases, the interest of the Egyptian consumer to buy and use it is weak, except in its production regions. This is, because the Egyptian consumer is not used to it and because of its high prices which vary from L.E 12 to 18 per kilogram for the good varie-ties and from L.E 20 to 30 per kilogram for excel-lent varieties, and in the shadow of the decrease in the produced amounts from cotton seed oil due to the recent decrease in cotton production and there is no main source in enough degree to depend on, to restrict our imports from oil in general and from olive oil in particular. The problem of research is restricted in recognizing the nature of olive crop market in Egypt and also the status quo of food gap from it, and out of this standpoint, the re-search aimed at analyzing the current structure of production and consumption of olive crop and olive oil and also the structure of its foreign trade along with shading a light on the relative ad-vantages of this crop, and the competitive situation of the Egyptian olive in the international market. And for achieving research aims, the inductive method was depended on, in the economic analy-sis and also econometric methods were used, also the scientific references and obtaining the neces-sary data of analysis from different resources dur-ing the period (1991–2004) were depended on. The analysis results showed that there is a signifi-cant increase in evolution of total area, production area, productivity, and production of olive during study period. In regard to the most important gov-ernorates in olive production, it is shown that Fay-oum governorate occupied the first grade in re-garding cultivated area followed by Matrouh, North Sinai, Nobaria, Ismaelia and Cairo respec-tively during 2004, while Matrouh governorate occupied the first grade in regarding production area and followed by Fayoum, Nobaria, North Sinai, Giza and Ismaelia respectively, but from the productivity respect, El Behira occupied the first grade and followed by Bennisweef, Giza and Monofia respectively. And by studying some indi-cators of food gap of olive and olive oil in Egypt, it is shown from analysis that there is a significant increase in evolution of oil consumption and the increasing rate of the annual consumption is slightly equals its counterpart related to production evolution, i.e. more than 95% of national produc-tion is directed basically to consumption. In regard to studying some foreign trade indicators of olive crop and olive oil in Egypt during the period (1990 – 2004), it is shown from analysis that there is an oscillation in the amount and value of olive oil exports up and down during the first and sec-ond stages of the study and this appears from the suitability of the cubic figure to express the evolu-tion of both. By studying average export price of olive oil, it is shown that there was a statistical significant decrease during the study period. As for the import price, there was an oscillation along

Dithiocarbamate mancozeb, an organometallic fungicide, was administered orally to male Wistar rats in two forms, pure technical 85% and formulated 80% WP, at sublethal doses of 125, 250 and 500 mg/kg b.w. for 28 days. Clinical chemical endpoints were measured after 2, 3, and 4 weeks of treatment initiation.  Data disclosed that both compound formulations affected significantly serum enzyme activities particularly liver enzymes in a dose and time-dependent manner, compared with control. Such changes were accompanied with significant alterations in other parameters like; total protein, albumin, glucose, total lipids, triglycerides, cholestrol, urea, and creatinine.  Furthermore, histological examination of liver and kidney showed several histopathogenic ubnormalities in the examined tissues of rats exposed to mancozeb either technical or formulated.

Canino apricot trees received four sprays of magnesium sulphate at 0.5%, 1.0% and 3.0%, boric acid at 0.2, 0.5 and 1.0%, ascorbic acid at 250, 500 and 1000 ppm, Vitamin B complex at 100, 200 and 400 ppm and a combination of the medium concentrations of each substrate were evaluated during 2004 and 2005 seasons. Single or combined application of magnesium, boron, ascorbic acid or vitamin B complex was favourable for improving leaf area, leaf mineral content (N, P, K and Mg), yield as well as physical and chemical properties of the fruits compared to untreated trees. The promotion effect was associated with increasing the applied concentrations. Using magnesium, born, ascorbic acid and vitamin B complex, in descending order was very effective in improving growth, nutritional status, fruit quantity and quality. Carrying out four sprays at starting growth, after blooming, after fruit setting and at three weeks later with a combination of 1.0% magnesium sulphate, 0.5% boric acid, 500ppm ascorbic acid and 200 p.p.m vitamin B complex suggested to be beneficial in improving growth, nutritional status, yield and fruit quality of “Canino” apricot.

Bacterial angular leaf spot disease caused by Pseudomonas syringae pv. lachrymans is an important foliage disease of cucumber, under protected cultivation system. The present work was planned to control the disease using bio-agents and abiotic agents alone or combining, under greenhouse and commercial plastic house conditions. Data obtained indicated that application of bio- and abiotic agents decreased severity of bacterial angular leaf spot disease of cucumber, compared with the control. Fluorescent Pseudomonads (Pseudomonas aeruginosa, P. fluorescens and P. putida isolates) were more effectiveness than isolate of Bacillus subtilis to reduce the disease severity, when they were applied as soil drench treatment. Application of abiotic agents as foliar treatment was more effective than as seed treatment to decrease the disease severity. Isolates of P. fluorescens or P. putida as bio-agents and salicylic acid or ethephone as abiotic agents were the most effective against the disease. Disease severity was significantly reduced by increasing rates of abiotic agents. However, interaction between bio-agents (P. fluorescens or P. putida isolates) as soil treatment and abiotic agents (salicylic acid or ethephone) as foliar treatment greatly decreased severity of bacterial angular leaf spot disease of cucumber, under greenhouse and commercial plastic house condition, compared with the control. Combination between P fluorescens isolate as soil treatment and salicylic acid as foliar treatment were the most effective against the disease

Larval parasitoids of the potato tuber moth, Phthorimaea operculella Zell. were surveyed in potato and tomato fields in Menofyia Governorate in 2003. Three species were found to attack P. operculella larvae infesting potato plants; the endoparasitoids, Apanteles litae var. operculellae Nixon and Diadegma molliplum Hlmgrn. and the ectoparasitoid, Bracon instabilis Marshal. Meanwhile, only B.instabilis was found to attack the larvae infesting tomato leaves. Percentages of parasitism in potato fields averaged 10.8, 5.6 and2.6 % by B.instabilis, A.litae and D.molliplum, respectively. The total percentages of parasitism by the three species ranged from 11.0 to 28.6 % with an average of 19.1 % in potato field, while it ranged in tomato fields from 0.0 to 21.4 % with an average of 11.1 % by B. instabilis

Preparationof either Bacillus thuringiensis or Trichoderma harzianum  were used as seed coating or soil application for management of root-knot and root rot disease complex caused by the root-knot nematode, Meloidogyne javanica and the fungus Rhizoctonia solani on soybean plants. Number of galls, root galling, egg masses and disease severity were reduced sharply on plants treated with both biocontrol agents, either as seed or soil application compared with non-treated plants. Soil application with both biocontrol agents was the best method in reducing nematode and fungus disease severity. Plant growth parameters i.e. fresh shoot and root weight, dry weight and number of pods and bacterial nodules were markedly increased with all treatments of biocontrol agent either with seed or soil treatment compared to plants grown in infested soil with either pathogens alone or combined. Results show that plant survival was more affected when R. solani was alone or combined with M. javanica. Seed coating was considered the effective method in increasing survival plants. The biochemical analysis of treated plants with both biocontrol agents were affected compared to non-treated plants grown in pathogen infested soil. The biochemical parameters i.e. chlorophyll A and B, carotein, phenols and amino acids were enhanced in bioagent treated plants compared to non-treated plants

A promising cotton inbred line characterized by high yielding ability, earliness in maturity and better fiber quality was developed via pedigree selection from the subsequent segregating generations of a cross between the two long-staple cvs.; Giza 89 and Giza 86 by the Cotton Breeding Section of the Cotton Research Institute. The purpose of this investigation aimed at assessment of the superiority of the physical and fine structural properties of the promising line derived from the cross (Giza 89 x Giza 86) over its parents. The results indicated that: -  The promising line surpassed its parents in upper half mean length, uniformity index, fiber strength, fiber elongation, micronaire value, maturity ratio, hair weight, dry fiber ribbon width, swollen fiber diameter, convolution number / cm., reversals number/ cm. and yarn strength. - There were highly significant positive correlations between upper half mean length, uniformity index, convolution number/cm., fiber bundle strength and yarn strength. - Highly significant negative correlations exhisted between dry fiber ribbon width, swollen fiber diameter, reversals number and bundle strength.   The promising line is now under propagation for growing as a commercial cultivar and would replace both parents in their growing areas.

A field experiment was carried out for two seasons 2001 and 2002 at Ismailia Agric. Res. Station to study the comparative effect of farmyard manure (FYM) application, individually or in combination with natural minerals, as sources of micronutrients. Such effect was studied during successive growth stages of wheat (vegetative stage, flowering stage and harvest stage), as well as after maize harvesting, on plant growth, nutrients uptake and wheat - maize productivity. The experiment was designed in a randomized complete block design with three replications. Two levels of FYM (2 % and 3 %) and three natural minerals, i.e., magnetite (iron oxide, Mag.), basic slag (Bas.) and manganese dust (Md.) at three rates 0.02 %, 0.05 % and 0.07%, respectively. Obtained results revealed that, at vegetative stage, mineral fertilizers (MF) treatment positively affected the dry matter of both shoots and roots of wheat plants along with contents of nitrogen and potassium in both shoots and roots as well as shoot/root ratios. At flowering stage, obtained data showed that applied farmyard manure at the rate of 3 % (F2) significantly affected the dry matter of both shoots and roots as well as their contents of N, P and K. A similar trend was obtained for micronutrients uptake at the two indicated growth stages of wheat, which recorded high values when FYM, at a rate of 3 % (F2), was applied. On the other hand, obtained results indicated that applied FYM at the rate of 2 % (F1) with high rate (0.07 %) of each of the used natural minerals and FYM at the rate of 3 % (F2) in combination with the moderate rate (0.05 %) of such minerals recorded high values of all tested parameters. In addition, Basic slag (Bas.), generally, gave the highest values, over control, of dry matter content and macronutrients uptake during the studied two growth stages of wheat, (vegetative and flowering stages). The agronomic yield components of wheat (straw, grains and weight of 1000 grains) were increased when MF was applied; such significant increases were obtained in maize yield (residual effect) as a result of applied FYM individually or combined with natural minerals.

Random samples were collected from Giza Qualubyia and Minufyia Governorates during summer, autumn and winter 2001. The collected samples were litter, poultry food and feather from chickens, ducks, pekeeny ducks, geese, rabbits (as a domestic animals) and quails, rozella birds, zebra birds and kockteel birds (as a wild animals which were in captivity). Mites belonging to twenty-seven families of four suborders; viz., Gamasida, Actinedida, Acaridida and Oribatida plus the hypopal stage of family Acaridae, were collected. Out of 27 families, 24, 14 and 11 were found in Qaliobia, Giza and Minufyia Governorates, respectively. However, number of mites, percentage of occurrence and dominance differentiated families in and between localities. Number of mites during autumn season was the highest representing 21 families followed by summer then winter. Hypopal stage represented about 20% of mite population in autumn season while no hypopal stage in summer but nil in winter. Litter harbored mites of all 27 families and hypopal stage which was not found in feather and food. The percentage of mites and hypopal stage was 89.39% in litter, followed by feather (9.51%) then food (1.1%). Only 6 and 5 families were found in food and feather respectively. Feather of Pekeeny ducks harbored 49.5% of mites while chicken’s feather harbored 42.6%. The percentage of mites in leftover food was 89% while it was 11% in food before feeding. The most common mite families in this study were Acaridae, Glycyphagidae Pyroglyphidae, Cheyletidae, Ascidae and Dermanyssidae.  Declaration of the role of the animals under investigation and their habitat as a source of stored product mites also the dominance of occurrence of the recorded mite families were discussed in details

The study was aimed to shed light upon the factors affecting on the safety and health status of babies of young mothers. The study includes 60 young mothers of ages between 14 to 18 years in Mekka (El-mokarrama). The results showed that 53.33% of the studied cases having normal weights up to delivery and 40% of them were less than 16 years; a trend that make them suffering from several diseases. Results also showed that 60% of young mothers prefer the Governmental hospital for delivery and 83.33% of these cases had only one delivery that achieved normally, while 33.33% of the young mothers having two successive deliveries with a period in between of less than one year.  In spite of the importance of normal breast feeding, it was extended only for 6 months in 48.33% of the cases while 11.66% of young mothers extend breast feeding to one and halve years. A bortion case was occurred in only one case of the tested young mother representing 26.66% and some times it occurs in two cases with a level of 6.66% of the tested sample. Regarding the weight of the babies delivered for young mother they indicate less weight than the normal (2.5 Kg) representing 23.33%, and 73.33% of the babes realize good health status. On the other hand, hepatitis was found to occur with a level 50% and vomiting 21.66% and 11.66% of babies suffering from each of intestinal trends, food allergy and Bronchitis aspects. Food history proved that 66.6% of the young mothers prefer white bread followed by rice (31.67%). The normal bread (Balady) and potatoes showed a level of acceptance of 31.67% and 25% respectively. Young mothers prefer to consume sugars (71.67%) followed by chocolates (51.61) and 68.3% of them prefer to use vegetable oils, while 75% consume poultry / week. The consumption of dairy by young mothers was some what lowered (40%) than that of cheese which was 51.67%. The ratio for ready to eat foods that was found to be accepted by the investigated young mothers was 45% (Tea), 25% (Coffee), 18.3% (carbonated beverages), and 38.3% (Fruit Juices).
