Significance Most hypotheses explaining the evolution of sociality in insects assume that positive selection drives worker traits. Yet we know little about extent natural acting on social insects. We produced a map for honey bee through analysis 40 individual genomes. found strong evidence genes and regulatory sequences, discovered mutations worker-biased proteins tend to have greater fitness effects than queen-biased proteins. also many instances influence traits, suggesting phenotypes...
In addition to color, ash and electrical conductivity (EC), the levels of 14 minerals were investigated in 23 varieties honey from Saudi Arabia six other countries. The quantities macrominerals obtained as follows (in ppm): K (298.60–491.40), Mg (80.70–199.30), Ca (60.75–99.95), P (21.10–33.29), Na (15.69–26.93). trace Fe (67.18–98.13), I (12.61–94.68), Mn (4.15–6.04), Zn (3.44–5.72), Li (1.15–4.26), Co (1.00–1.32), Ni (0.15–0.67). heavy metals Pb Cd found be 0.06–0.23 0.00–0.16,...
In 23 types of honey from Saudi Arabia and six other countries, the levels some minor components floral pigments as well physicochemical characteristics were investigated. Most tested honeys, e.g. Acacia Seder showed high values density total soluble solids low water content compared to exotic ones. Some Manuka samples had higher HMF contents than permitted levels. All honeys acidic; however acidity over those levels, while most remainding comparable or acceptable. Also, Egyptian contained...
The contribution of a bee plant species to honey production depends on the plant's nectar secretion quality and quantity, which is mainly governed by biotic abiotic factors. aim current study, was investigate dynamics potential 14 major target area. We examined quantity sugar per flower five times day using washing technique direct measuring with calibrated capillary tubes. average amount varied from 0.41 mg/flower 7.7 (P < 0.0001). used extrapolate hectare land. Accordingly observed vary...
Apis mellifera jemenitica Ruttner (= yemenitica auctorum: videEngel 1999) has been used in apiculture throughout the Arabian Peninsula since at least 2000 BC. Existing literature demonstrates that these populations are well adapted for harsh extremes of region. Populations native to Saudi Arabia far more heat tolerant than standard races often imported from Europe. Central highest summer temperatures Peninsula, and it is this region where only survives, while other subspecies fail persist....
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed the Code has already been discussed Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; 2009a-b; Dubois Gentile Snell Minelli Cianferoni Bartolozzi 2016; Amorim et al. 2016). This was again raised a letter supported 35 signatories published journal Nature (Pape 2016) on 15 September 2016. On 25 2016,...
The western honey bee originated in Asia before adaptively radiating into Africa and Europe.
Heat stress elicits the expression of heat shock proteins (HSPs) in honey bee subspecies. These highly conserved have significant role protecting cells from thermal-induced stresses. Honey bees subtropical regions face extremely dry and hot environment. The HSPs nurses foragers indigenous (Apis mellifera jemenitica) imported European ligustica Apis carnica) subspecies after treatment were compared using SDS-PAGE. Hsp70 Hsp82 equally expressed all tested when exposed to 40 °C 45 for 4 h....
Abstract Honeys originating from Sidr ( Ziziphus spina‐christi L.) and Talh Acacia gerrardii Benth.) trees in Saudi Arabia exhibited substantial antimicrobial activity against pathogenic gram‐positive bacteria Bacillus cereus , Staphylococcus aureus ), gram‐negative Escherichia coli Salmonella enteritidis a dermatophytic fungus Trichophyton mentagrophytes ). The diameter of zones inhibition represents the level potency honey samples. Precisely, showed significantly higher antibacterial all...
The compliance with honey standards is crucial for its validity and quality. present study evaluated the botanical origin (pollen analysis) physicochemical properties: moisture, color, electrical conductivity (EC), free acidity (FA), pH, diastase activity, hydroxymethylfurfural (HMF), individual sugar content of forty local imported samples. exhibited low moisture HMF (14.9% 3.8 mg/kg, respectively) than (17.2% 23 respectively). Furthermore, showed higher EC activity (1.19 mS/cm 11.9 DN,...
The impact of agrochemicals on pollinators, especially honey bees, has drawn significant attention due to its critical implications for worldwide food stability and ecosystems. Given the potential threat insecticides bees may encounter multiple simultaneously during foraging. This study investigated toxic effect an insecticide mixture (IM) containing acetamiprid (neonicotinoid) deltamethrin (pyrethroid) survival cognitive appetitive performance Apis mellifera jemenitica, a vital native...
Ascosphaera apis is one of the major fungal pathogens honey bee broods and causative agent Chalkbrood disease. The factors responsible for pathogenesis disease are still not fully understood, increasing resistance A. to commonly used antifungal agents necessitates a search new control this in vitro activities 27 plant essential oils against two isolates (Aksu-4 Aksu-9) were evaluated. Out tested, 21 found be effective killing both apis. Based on their minimum fungicidal concentration (MFC)...
The uncommonly encountered bee tribe Tarsaliini (Apinae) is recorded from the Arabian Peninsula for first time, and based on a new species of genus Tarsalia Morawitz. tribes Ancylaini are diagnosed their differences highlighted. kindahensis Engel, species, described figured eastern portion Najd central-eastern Saudi Arabia (Qassim Riyadh regions). most similar to T. mimetes (Cockerell), known only Egypt Sudan, as well larger persica (Warncke) Iran. These three morphologically largely...
Abstract For decades, the American palm weevil (APW), Rhynchophorus palmarum , has been a threat to coconut and oil production in Americas. It recently spread towards North America, endangering ornamental palms, expanding date production. Its behavior presents several parallelisms with closely related species, R. ferrugineus red (RPW), which is biggest palms Asia Europe. both semiochemicals have used for management. However, their control far from complete. We generated an adult antennal...
This study was conducted in the Assir region of southwestern Saudi Arabia to compare activities honeybee colonies indigenous Apis mellifera jemenitica (AMJ) and imported carnica (AMC) during late summer autumn 2009 2010. The results showed that workers two races exhibited relatively similar forage timings throughout period (August-November). highest numbers foraged were recorded at 6:00 am, 10:00 am pm, while lowest 8:00 12:00 pm 4:00 pm. Although foraging activity negatively affected by...
Abstract The nectar secretion of Ziziphus flowers was studied by removing and measuring the every four hours, for two consecutive days, from 88 trees (‘repeated sampling’). In another 120 same trees, accumulated sugar measured at end flowering stage. mass determined following washing technique. total amount per tree calculated multiplying number average secreted flower. produced flower in repeated sampling 0.79±0.54 mg/flower (range 0.09 - 2.48 mg). each investigated 1.43±0.53 mg, 0.72±0.27...
Apis mellifera jemenitica is the indigenous race of honey bees in Arabian Peninsula and tolerant to local drought conditions. Experiments were undertaken determine differences associative learning memory bee workers living arid zone Saudi Arabia, utilizing proboscis extension response (PER). These experiments conducted on (A. m. jemenitica) along with two introduced European races carnica A. ligustica). The data revealed that amenable PER conditioning may be used within olfactory behavioral...
This study investigates how storage conditions (temperature and duration) may affect the physicochemical parameters, especially free acidity (FA), of Talh honey originating from Acacia gerrardii that have naturally high FA levels. Fresh samples were kept at 0, 25, 35, 45 °C, analyzed monthly over a period eight months. The was monofloral with 69% A. pollen content. (FA) freshly harvested higher (93 ± 0.3 meq/kg) than standard limits (≤50 remained stable 0 °C throughout period. A...
The large carpenter bees (Xylocopinae, Xylocopa Latreille) occurring in central Saudi Arabia are reviewed. Two species recognized the fauna, (Koptortosoma) aestuans (Linnaeus) and (Ctenoxylocopa) sulcatipes Maa. Diagnoses for keys to of these prominent components Arabian bee fauna provided aid their identification by pollination researchers active region.
