Toxicity results revealed that mustard oil has low toxicity versus the neem oil with LC50 values of 7.99 and 20.30 when tested against 2 nd and 4 th larval instars, respectively. The toxicity index were 0.0024% and 0.0014 against 2 nd and 4 th instar larvae, respectively. A similar trend was recorded for both neem and mustard oils in the biochemical changes of protein and transaminase enzymes activities [aspartate aminotransferase (AST), alanine aminotransferase (ALT)] which decrease in both tested 2 nd and 4 th instar larvae at all times intervals (1, 3, 5 and 7 days).

Results showed that, wheat flour showed higher moisture and total carbohydrate contents. Tomato pomace powder showed high crude protein, and crude fiber contents. Mango seeds kernel powder had the highest lipids content and pomegranate peels powder had the highest ash and crude fiber contents. For total phenolic and flavonoid content, TPP contain the highest total phenolic and flavonoid content followed by PPP and finally MSKP. Also, the partial replacement of wheat flour with TPP, MSKP and PPP increased chemical composition percentage (moisture, crude protein, lipids, ash, and crude fiber), minerals content (i.e., K, Ca, Mg, Na, Mn, Fe, and Zn) and dietary fiber content (i.e., total, soluble and insoluble dietary fibers) of biscuit samples. However, total carbohydrates were decreased in parallel with increasing the level of substitution compared with control biscuit samples.

The annual amount of imports from it in the average period (2014-2017). With regard to the free and private alternative to leaving the quantities of imported corn oil distributed freely in different countries according to the lowest prices and according to the exporting capacity of the countries, it was found that the quantities imported from corn oil were distributed in two countries, Saudi Arabia and the United States of America, with an estimated rate of 68.81% and 31.19% on the sequence is out of the total imported quantities, and this alternative has achieved an estimated cost of approximately 43721.35 thousand dollars, meaning that it saves about 4290.57 thousand dollars, which represents 8.94% of the current model. It is clear from the study that the (free) alternative to distributing imports of corn oil is the best proposed alternative, because this alternative has achieved an estimated cost of approximately 43721.35 thousand dollars, meaning that it saves about 4290.57 thousand dollars, which represents about 8.94%. Second: The geographical distribution of sunflower oil imports in Egypt. Alternative (European Union Countries Market): It clarifies that the quantity of Egypt's imports of sunflower oil from all countries of the European Union market is not less than the average amount that Egypt imported from each country during the study period, so that it does not exceed the average of its export capacity and not more than average of the total amount of Egypt's imports during the average period (2014-2017). It is clear from the study that an alternative (European Union countries) to distribute sunflower oil imports is the best proposed alternative, because this alternative has achieved an estimated cost of about 413076.06 thousand dollars, meaning that it saves about 17191.86 thousand dollars, representing about 3.99%. The study recommended the following proposals: Preparing sound model plans for the geographical redistribution of Egyptian imports of agricultural crops in general and oil crops in particular in the form that is in favor of the Egyptian balance of payments. Redistributing Egyptian imports of corn oil and sunflower oil from other countries, commensurate with the export capacity of these countries, that could be achieved by reducing the proceeds of imports under restrictions, and it is clear from the study that the first (free) alternative to distributing imports of corn oil is the best alternative and the exporting power of the exporting countries.

Four nanoparticles (chitosan, Hydroxyapatite, chitosan hydroxyapatite and silver hydroxyapatite), one bio-agent effective microorganisms (EMs) compared to one synthetic acricide (bifenzata) were tested against the female adults and eggs of Tetranychus urticae and its predatory mite Amblyseius gossipi using standardized method of bioassay under laboratory conditions. Effect of the tested agents on the activity of carbohydrates enzymes, total lipid and total protein content were determined. The results revealed that chitosan (NPs) showed significantly adulticidal activity against T. urticae. Furthermore, EMs was the most effective treatment on the eggs of T. urticae followed by bifenzata under laboratory conditions. Therefore, nanoparticles and EMs appeared to be highly safe and selective against Amblyseius gossipi. This study suggests the possible use of nanoparticles as safe alternatives to conventional acaricides and compatible with integrated pest management practices. They might be contribute to future applications in pest control for sustainable agriculture.","PeriodicalId":14975,"journal":{"name":"Journal of Agricultural Research","volume":"47 1","pages":"951-961"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48633338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
