Osmotic concentration in three races of honey bee, Apis mellifera L. under environmental conditions of arid zone

Abstract

Hemolymph osmolarity has great effect on honey bee health, especially in arid and semi-arid zones. It regulates water and nutrients in stressed tissues. Osmotic concentration in three races (, and) of was tested in central Saudi Arabia during spring and summer seasons in 2015. Newly emerged bee workers were first marked and later their hemolymph was extracted after intervals of 1, 5, 10, 15, 20 and 25 days. A significant positive correlation between age and osmolarity was found in all three races during spring and summer seasons. The lowest combined osmotic concentration for all three races was found after 1 day interval, while the highest osmotic concentration was recorded after 25 days. Among all races, showed significantly high osmotic concentration after 25 days in spring and summer seasons as compared to the other two races. Only showed similar osmotic concentration after 10 and 15 days in both spring and summer seasons compared to other two races. Mean osmotic concentration of all three races was significantly different after 20 and 25 days in spring and summer seasons. Overall mean recorded during summer was significantly higher than the mean of spring season. Combined osmotic concentration in young drones of all races was significantly lower than that of old drones during spring and summer seasons.

A Critical Review and Perspective of Honey in Tissue Engineering and Clinical Wound Healing

“…Due to the recent rise in antibiotic resistance, there has been an increased need for alternative treatment methods. 1,2 Honey offers a natural component that can be used directly in a clinical setting or incorporated into tissue-engineered scaffolds. 2 In this review, the overall properties of honey will be summarized, as well as its current use in wound healing and the potential of honey-based tissue-engineered products.…”

“…12 However, honey osmolarity varies greatly and consequently, as do the antimicrobial benefits, where an increased water content decreases these effects. 2 Honey is naturally acidic, generally possessing a pH ranging from 3.2 to 4.5. 6 Furthermore, the unique presence of methylglyoxal and dihydroxyacetone in Manuka honey has been observed, in vitro, to inhibit urease derived from jack beans.…”

“…The hemolymph osmolarity of bees can greatly affect their health and depends on factors such as geographic region, age, and weather season. 2 Once collected, the deposited nectar mixture is slightly dried, reducing water content and increasing the concentration, producing the viscous honey. 3 While honey composition can vary widely across varieties, it is generally considered to be primarily composed of sugar (40% fructose, 30% glucose, 5% sucrose, and other disaccharides in small quantities: maltose, isomaltose, nigerose, turanose, and maltulose) and water (up to 20%) with additional amino acids, enzymes, minerals, and vitamins.…”

Effect of season and behavioral activity on the hypopharyngeal glands of three honey bee Apis mellifera L. races under stressful climatic conditions of central Saudi Arabia

“…In Saudi Arabia, the summer temperature is extremely high and often exceeds 45 °C, and the humidity is very low; in winter, the temperature can fall below 0 °C. (Ali et al 2017;Alqarni 2006;Alqarni et al 2011;Iqbal et al 2018b). Apis mellifera carnica Pollmann (AMC) and Apis mellifera ligustica Spinola (AML) are exotic bee races imported annually by the beekeepers to boost agricultural production (Alqarni et al 2014).…”
