This laboratory study aimed to evaluate the efficiency of two biological agents Beauveria bassiana (Bals) and Bacillus thuringiensis (Kursaki) and four chemical pesticides Levo 2.4 SL, Aster 20 SL, Difuse 450 SC, and Matrixine Plus EC on four important main pests that infect tomato plants. The pests studied were whitefly Bemisia tabaci (Hemiptera: Aleyrodidae), Meyrick Tuta absoluta (Lepidoptera: Gelechiidae), Sulzer Myzus persicae (Hemiptera: Aphididae) and Koch Tetranychus urticae (Acari: Tetraanychidae). The results show that the pesticide Matrixine Plus recorded the highest average of mortality of both larval and adult stages of all four pests. The average of mortality for adults and larvae of whitefly were 96.67% and 86.67% respectively. The average of mortality for adults and larvae of Meyrick was 93.33% for both stages, while the percentages for adults and larvae of Sulzer and Kotch were 96.67% respectively after seven days of exposure. The lowest averages of mortality were recorded for Antario on whitefly adults and for Difuse on whitefly (both (16.67%). Difuse caused the lowest average of mortality (26.67%) on Meyrick adults, whereas Antario caused the lowest average of mortality of 20% on Meyrick larvae. The results show also that Antario caused the lowest average of mortality of 23.33% on adults and 16.67% on larvae. Similarly, Difuse was recorded the lowest average of 20% on adults while Antario caused the lowest average of mortality of 26.67% on larvae after one day of treatment.

This study aimed at identifying the most important factors affecting bee honey production, by performing a comparative study for the economic efficiency and the technical efficiency, data were obtained from field sources in light of a random sample constituted a percentage of 5% taken from honey producers from 51 apiaries at the season of 2018- 2019. The research, in estimating economic efficiency and dividing its components into technical and allocative efficiencies, adopted the data envelopment analysis using the model of entry orientation in light of fixed and variable returns in checking the technical efficiency, and in light of variable capacity return  in checking allocative efficiency and cost efficiency, where we note that technical efficiency varied between (0.1-1) with an average of 27%, i.e. the sample is capable of increasing its production by 73% to reach the optimal volume, whereas we note that 96.3% of beekeepers are working with increasing capacity return. The technical efficiency, in light of the variation in capacity return, has varied between 0.5 minimum and 1 maximum with an average of 0.60, and that the apiaries which fell on the possible production curve were 12%. The economic efficiency on the other hand, reached an average of 0.46 and that means the bee breeding farms could achieve the same production level in light of costs reduction of 54%, i.e. capable of producing the current amount using only 46% of the economic resources, and this is attributed to the inadequacy of the allocative efficiency and the improper use of resources. The study recommended the use of amounts that realize the economic efficiency and, the redistribution of resources in a way that guaranties achieving the same level of production or more in light of costs reduction.

The study was carried out using 405 chicks with a one-day-old, type Rose 308. The birds were randomly distributed to nine experimental treatments, with three replicates per treatment (15 birds/replicate). The birds were fed ad libitum during the 42-day trial period, 9 diets were used for study in the starter and 9 diets in the finisher period, as protein source used the Vetch 12.5% and 25% as an alternative to soybean meal, Vetch was treated by soaking in water or acetic acid (1% concentration) or by adding activated charcoal 50 gm / 100 kg diets. The results of the 21-day starter level showed a significant difference (P < 0.05) for live body weight, weight gain, consumed feed, and feed conversion ratio between control treatment and Vetch treatments 12.5% and 25% soaked water, acid and activated charcoal. While there were no significant differences in Mortality% in the period 21 days, in the finisher period (22-42 days), the results showed significant differences (P <0.05) between control treatment, Vetch seed and Vetch seeds treatments for body weight, weight gain, consumed feed and feed conversion ratio, Also, there was no significant difference between treatments for mortality% in this period.
