Significance Honey bees pollinate the majority of crops, but their survival is under threat. The bee parasitic mite Varroa destructor a major cause honey decline. successful control mites depends on small number in-hive acaricides. Species-specific activation chemical coumaphos powerful “pro-drug” approach to attain this selective toxicity and protect bees. We identified coumaphos-resistant population that escapes by down-regulating activating enzyme, P450 monooxygenase. Decreased rare...
Thyme honey is the most appreciated unifloral Greek in Greece as well around world. In an effort to investigate headspace composition of this type honey, 28 samples were analyzed by means solid-phase microextraction coupled a gas chromatography–mass spectrometry system. The botanical origin was ascertained pollen analysis, and displayed relative frequencies thyme between 18 41%. A total 62 compounds isolated, phenylacetaldehyde abundant (32.9% peak area). Possible markers are...
Abstract The analysis of the volatile fraction honey provides useful information for determination botanical and geographical origin. However, results obtained vary greatly upon extraction procedure employed. Four different isolation techniques were compared, that is hydrodistillation (HD), micro‐simultaneous steam distillation–solvent (MSDE), ultrasound‐assisted (USE) solid‐phase microextraction (SPME). From data obtained, USE SPME seem to be more suitable potent marker compounds. HD MSDE...
A new methodology for identification of pollen was developed based on FT-IR spectroscopy. Pollen samples twenty different plant species were collected and the diffuse reflectance infrared Fourier transform (DRIFTS) KBr pellet spectra recorded. Libraries created. Spectra unknown origin recorded compared with those corresponding library match value measured automatically using appropriate software (OMINC ver. 3.1). From same samples, microscopic slides prepared photographs grains used as a...
Abstract Finding marker compounds is a powerful tool in the determination of botanical origin honey. For this purpose flavour fraction Greek cotton honey was investigated. A striking characteristic type presence more than 35 phenolic extract, accounting for almost 60% total amount positively identified by gas chromatography/mass spectrometry. In comparison with honeys nine different origins, 15 could serve as potent markers honey, namely cinnamaldehyde (0.44%), cinnamyl alcohol (1.79%),...
A new method for mass percentage determination of fructose and glucose based on FT-Raman spectroscopy is evaluated with a standard HPLC-based method. spectra manipulation done via the spectrometer software, PLS (partial least squares) developed TQ Analyst software (Ver 1. 1a). The simultaneous quantitative uses an input range from 1700 to 700 cm(-1) without correction or baseline factors. standards used in are honey samples previously analyzed by HPLC obtain their concentrations glucose....
The use of Galleria mellonella as a model host to elucidate microbial pathogenesis and search for novel drugs therapies has been well appreciated over the past years. However, effect microorganisms with functional appeal in specific remains scarce. present study investigates treatment selected lactic acid bacteria (LAB) probiotic potential, potential protective agents by using live or heat-killed cells at 6 24 h prior infection Listeria monocytogenes Staphylococcus aureus therapeutic...
Protection of honeycombs from the Wax moth, Galleria mellonella, involves use physical, biological or chemical control methods. As may result in residues extracted honey, presence p-dichlorobenzene and naphthalene was investigated by solid-phase microextraction (SPME) coupled to gas-chromatographic/mass spectrometry (GC/MS). The method linear between 5 200 microg kg(-1) honey for 1 naphthalene. Limits detection were 0.1 kg(-1), respectively, naphthalene, while relative standard deviations...
SummarySummaryRoyal jelly protein degradation was monitored by Fourier-transform infrared (FTIR) spectroscopy. The samples of royal were stored at room temperature for 10 weeks 4°C and -20°C 31 weeks. FT-IR spectra then recorded the ratio peak area in 1545 (amide II) 1656 cm−1 I) calculated. areas associated with proteins. It observed that increased over time increasing storage temperature. is maintained three days temperature, seven 21 -20°C.ResumenSe ha supervisado la degradación de...
SummaryPealius machili (Takahashi, 1935), the mulberry whitefly Pealius mori 1932) and nesting Paraleyrodes minei (Iaccarino, 1990) were found infesting in Greece. The first species is reported for time outside China, second was recorded Greece, third represents a new association. A brief description, illustrations information on distribution potential damage control of each are provided. results showed that nymphs parasitized, although at low rate. developed high infestation levels thus may...
SummaryDiagnostic patterns using PCR—RFLPs analysis of two mtDNA gene segments (16s rDNA and CO I) were shown to discriminate Africanized honey bees from Greek Cypriot bees; high values net nucleotide sequence divergence observed among the other populations studied. The tree obtained by UPGMA method ensured that bee is discriminated Greece Cyprus. These results could be useful for early detection bees.
Background: The silkworm (Bombyx mori L.) and its cocoon are rich in bioactive proteins like sericin fibroin, as well enzymes such serrapeptase, which possess anti-inflammatory skin-healing properties. This study aimed to evaluate the vivo effects of various products, including patches extracts from body glands, on healing second-degree burns. Methods: Hairless, female SKH-2 mice were used model tested formulations containing 1%, 10%, or 20% gland extracts, cocoon-derived patches. In...
Melia azedarach L. extracts were studied in comparison with selected synthetic in-secticides against the mulberry whiteflies Pealiusma chili and P. mori under labora-tory conditions. Morus alba (cv. “Early Spring”) leaves infested by white-flies exposed to of green fruits, l-cyhalothrin (10% a.i.) con-trol. Also, white after treatment same insecticides provided silkworms for consumption. Results have shown that there signif-icant differences nymphal mortality among treatments. effective...
