Canola plants were sprayed with three rates of K and SA separately and together. The concentrations of SA with a surfactant triton 0.1% and concentrations of K sprayed after 30 days of sowing by one week interval for three times using hydraulic sprayer. Results indicated that K and SA provided good nutrition and resistance for pathogens, enhanced plant height (cm), number of branches/plant, fruiting zone (cm), seed yield/plant (g), seed yield/fed and oil percentage of canola cultivar (Serw 4) in the reclaimed land. K and SA separately or in combination at the rate of (6.0 cm−1 + 300 mg−1 SA) provided the best nutrition for enhancing resistance of plants against biotic and a biotic...

The isolates were identified using the conventional methods. The virulence of nine entomopathogenic fungi Metarhizium anisopliae isolates (M1, M2, M3, M4, M5, M6, M7, M8 and M9) were tested against Tenebrio molitre L. Results proved that (M1) was more effective against larvae compared with all other isolates. the highest concentration of 1×10 spores/g revealed 71,56,47,31,37,52,41,46 and 64% mortality percentage for M1, M2, M3, M4, M5, M6 M7, M8, and M9, respectively at tenth day after treatment.

The present work aimed to perform the nutritional and chemical profiling and biochemical characterization of bee pollen (BP), bee bread (BB), and royal jelly (RJ) and study their applications in the fortification of functional fermented dairy products. Their effects on starter cultures and the physicochemical and sensorial quality of products were monitored. A molecular networking analysis identified a total of 46 compounds in the three bee products that could be potential medicines, including flavonoids, fatty acids, and peptides. BB showed the highest protein and sugar contents (22.57 and 26.78 g/100 g), which cover 45.14 and 53.56% of their daily values (DVs), with considerable amounts of the essential amino acids threonine and lysine (59.50 and 42.03%). BP, BB, and RJ can be considered sources of iron, as 100 g can cover 141, 198.5, and 94.94% of DV%, respectively. BP was revealed to have the h...

The study was carried out at an experimental farm, Faculty of Agriculture, Suez Canal University, Ismailia. The results revealed that 21 species of insect pollinators belonging to 14 families under four orders visited canola flowers. The abundance of Hymenoptera insects reached the maximum of 67.90%, followed by Diptera 14.97%, Coleoptera 13.61%, then Lepidoptera 2.26% as average of both seasons. In open pollination, Colletes lacunatus had the maximum percent abundance in the two seasons (30.45 and 29.34%, respectively) followed by Apis mellifera (12.34 and 17.73%, respectively), compared to other bees and different pollinators. Peaks of foraging activity of both C. lacunatus and A. mellifera were mainly observed from 1:00 to 3:00 pm and they corresponded to the number of flowering plants. Open pollination increased the number of pods per plant, seeds per ...

Insect pests, such as aphids, are major threats in terms of yield reduction. Induced resistance in wheat using salicylic acid as a foliar application was tested on the farm of the Faculty of Agriculture, Suez Canal University during 2012/2013 and 2013/2014 seasons. Three wheat cultivars, Gemeza 9, Sakha 93 and Giza 168, were sprayed three times with two concentrations of salicylic acid (SA), 200 mg/l and 100 mg/l, after early detection of aphid infestation by infrared thermal imaging. The infrared thermal imaging technique is based on significant differences in surface temperature between infested and healthy leaves. Imaging data are digital, and a computer program can be used to detect infestation rapidly. The results showed that aphid infestation raised the temperature of infested leaves, compared to healthy leaves. The range temperature difference between maximum and minimum temperatures (At) was 1.1 ...

Experimental observations were made during four periods of the day: 9:00-11:00 am, 11:00 am-1:00 pm, 1:00-3:00 pm and 3:00-5:00 pm, starting from initial flowering until the final session. Observation time was five minutes during each period and four bee species were observed visiting each square meter area. Five spots of 1 m2 area were selected randomly, and the number of different species of bees visiting was counted for five minutes by using electronic stopwatch, voice recorder and digital video camera. The results of the study indicated that the four bee species were most abundant on sesame flowers between 11:00 am and 1:00 pm, and between 1:00 and 3:00 pm. Among the bees, Apis mellifera was the predominant species, followed by Ceratina tarsata, in the season of 2011, while a r...

Different samples of bee venom had an inhibitory effect against all types of investigated bacteria. The minimum inhibitory concentration of bee venom was determined. From these data, we can report that, when increasing the concentration of bee venom give more effectiveness against both bacterial strains "Gram-positive and negative bacteria".
