The present study was carried out to evaluate the biochemical effects of four plants extracts (<em>D. stramonium</em> L., <em>Hyoscyamus muticus</em> L., <em>Nerium oleander</em> L. and <em>Eucalyptus camalulensis</em> Dehn.) on the late instar larvae of the greater wax moth <em>Galleria mellonella</em> L. The results showed that treatment of <em>D. stramonium</em> L. 4% gave the maximum total mortality percentage (73.33%), while the minimum total mortality percentage was (13.33%) which recorded by N. oleander L. 4%. Biological parameters were studied under laboratory conditions, the life cycle decreased by increasing plant extract concentrations. The life cycle could be arranged in ascending order as follow: 58.33, 56.67, 62.67 and 69.00 day for the larvae treated with<em> D. stramonium</em> L. 4%, Sakran 4%, <em>E. Camalulensis</em> Dehn., and N. oleander L. 4%, respectively.

Red Palm Weevil is the most dangerous palm pest in Egypt and the Middle East. This study was conducted to evaluate some plants essential oils for use in the control of this pest in egg and larval stages. five individual different oils (orange oil, lemon oil , eucalyptus oil , castor oil, and basil oil)and three mixtures of (chilli+ thyme + lavender =)k1, mixture of (Colocynth and neem) = k2,and mixture of (Radicchio + turmeric +Silene ) = k3 with 5 concentrations of 1%, 3%, 5%, 7% and 9% for each one was used as aqueous solutions. Each concertation contains three replicates with ten eggs or larva for each replicate. The eggs were sprayed with different solutions while the larvae were fed on the sugar cane pieces after being dipped in the solutions for 20 seconds. The results of statistical analysis showed superiority the plant oils from orange and lemon showed remarkable mortality (p≤ 0.05) in the number of dead larvae and non-hatched eggs followed by eucalyptus, basil and Castor while other treatments recorded low number of mortalities of larvae and non-hatched eggs. The L.S. D values (2.49 ,6.19) for eggs and larvae respectively, showed that there were significant differences between oils and significant differences between concentrations. orange and lemon oil showed the strongest effect at 9% followed by the other concentrations, while k1 and k2 oil had no significant difference with the control at 1%. The study showed that orange and lemon oils as well as eucalyptus, basil and castor can be used in the control of this pest in the stage of the egg and larva.

Oilseeds contain different constituents with antioxidant activity especially phenolic compounds and tannins, this study was conducted to evaluate the possible effects of some domestic processes such as dehulling, soaking, ordinary and pressure cooking, germination, fermentation and microwave heating on the contents of phenolic compounds and tannins in some oilseeds. The data revealed that oil seeds could be considered as a rich source of oils and proteins. Phenolic compounds contents of raw oil seeds were; 978.4, 968.0, 862.75, 915.0 and 1063.4 mg/100 g, while, tannin contents were; 510.0, 490.0, 457.0, 457.0 and 440.0 mg/100 g on dry weight basis in peanut, sesame, soybean, safflower and sunflower, respectively. All processing treatments reduced the phenolic compounds except dehulling of sunflower seeds which was increased by 9.6%. Dehulling of oil seeds reduced tannin content by 9-26.5%, while during cooking processes, tannin leaching out in cooking water resulted in a reduction in its content by 4.5-19.6% for ordinary cooking and 5.2-20.2% for pressure cooking. Germination and fermentation processes decreased tannin by 12.5-34.7 and 13.6-49.0%, respectively. Microwave heating treatment had an effect in removal of tannins from seeds than other cooking methods. The reduction ranged between 8.8-24.4% of its initial content in raw oil seeds. The study concluded that all processing treatments used in the study had an effect on the oilseeds content from both phenolic compounds and tannins.

Betaine (trimethylglycine) is a nontoxic methylamine compound contains the amino acid glycine with three chemically reactive methyl groups. This review gives an overview of the roles of betaine as a feed additive on the performance, carcass, meat quality in livestock production. Biological functions of betaine are defined as an osmolyte, methyl donor, and carcass modifier. As an osmolyte, betaine regulates the cellular hydration status and alleviates osmotic stress. As a methyl donor, betaine plays an important role in methylation reactions. Therefore, betaine may partly replace other methyl donors such as choline and methionine in the diet. Betaine is also supposed to play a significant role in lipid metabolism and has lipotropic effects also participating in the protein synthesis. A review of the results of this study suggests that betaine supplementation was effective to improve the average daily gain significantly, increased feed consumption and improved efficiency of food utilization of ruminants and monogastric animals. Betaine has been characterized as a carcass modifier by increasing the lean carcass percentage and decrease fat percentage by reducing lipid deposition. In conclusion, this study implies that dietary betaine supplementation was efficacious on growth performance and carcass characteristics of livestock.

One of the chronic problems that pose a serious threat for honey beesˈ continuity and survival is pollen and nectar deficiency caused by annual weather fluctuations. The current study aims to find an effective solution for this problem by providing honey bee colonies with diets characterized by appropriate cost, nutritional rich value, palatability and positive impacts on various biological activities. Three new artificial diets were prepared, diet W: based on wheat germ, diet S: based on soya beans and diet M: based on a mixture of equal proportions of wheat germ and soya beans. In the current study, several investigations have been performed including consumption rates of examined diets, sealed worker brood, stored honey areas, coloniesˈ strengths and pollen grainsˈ weights. Outstanding palatability rates were reported for examined diets, especially for diet S. Moreover, distinguished impacts for all investigated diets have been recorded by fed colonies, including sealed brood areas, produced honey areas, population densities and collected pollen. Consequently, the current study highly recommend diets W, S and M to be applied in apiaries due to their prominent results related to activity and strength development of honey bee colonies.

This investigation was conducted during the two successive seasons i.e. 2018 and 2019 on Early Sweet Seedless grapevines grown in Eiat vineyard, El-Odesate district, Luxor Governorate, Egypt. Five treatments of GA3 urea plus active dry yeast, roselle, lemongrass spraying and unsprayed one (control) at various stage of cluster and berry development were evaluated. The experimental vines were arranged in a complete randomized design with three replications. GA3, roselle and lemongrass were applied thrice, where urea twice followed active dry yeast once. From the results, it could be concluded that spraying either GA3, roselle or lemongrass at pre-bloom, full bloom and pea stage. In addition, spraying 1.5% urea at pre-bloom and full-bloom followed 0.4% yeast at pea stage gave heavy and less compact clusters and hastens the ripening with fairly good Early Sweet Seedless berries quality. In addition, it could be used urea plus yeast as well as roselle or lemongrass instead of GA3 in grape production to overcome the adverse GA3 effects.

Fruit color development in table grapes growth and fruiting are affected by hot weather mainly in warm regions. Here, 2-year field study, during 2017/2018 and 2018/2019 seasons in a factorial experiment in randomized complete block design were conducted to study the effects of some of tested materials and time/stage of spraying on Flame Seedless grapevines grown in Upper Egypt and harvested during 15<sup>th</sup> May to 10<sup>th</sup> June. In this time, global and domestic markets of table grape are affected by quality of fruits focusing color in colored varieties. Thus, prices decrease considerably in the market. On other contrary, harvesting early (before mid of May) leads to at least a 50% increase in the total income. In this experiment methyl jasmonate and ABA are used at verasion stage followed by ethephon one time compared to spraying ethephon twice. all tested treatments are sprayed at different time/stages at 25 and 50 % colored bunched and the findings did not affect significantly on the yield components while using ABA or methyl jasmonate followed by ethephon one time improved berry quality in terms of berry color and firmness compared by spraying ethephon twice , on the other hand using methyl jasmonate and ABA affect significantly on reducing the uncolored and the best results were when spraying at 95 % berry softening approximately and 50% bunch coloring especially the methyl jasmonate. It could be recommended to use methyl jasmonate followed ethephon at 50% bunch coloring to improve berry and more coloring and keeping the berry quality after harvesting.
