Abstract Colony losses, including those induced by the colony collapse disorder, are an urgent problem of contemporary apiculture which has been capturing attention both apiculturists and research community. CCD is characterized absence adult dead bees in hive few workers a queen remain, ratio between brood quantity number heavily disturbed favor former, more than enough food present. Robbing behavior pests usually attacking weakened do not occur. In present paper, causes emergence this...
During their lifetime honey bees (Apis mellifera) rarely experience optimal conditions. Sometimes, a simultaneous action of multiple stressors, natural and chemical, results in even greater effect than any stressor alone. Therefore, integrative investigations different factors affecting have to be carried out. In this study, adult exposed thiamethoxam larval and/or stage infected with Nosema ceranae were examined. Newly emerged from colonies, non-treated or treated thiamethoxam, organized...

The main signs apathy, anorexia, fever, brown/red discoloration of urine, pale mucous membranes, icterus, splenomegaly, vomiting. clinicopathological Babesia infections slight to severe...
West Nile virus (WNV) is continuously spreading in Eastern and Southern Europe. However, the extent of vector competence Aedes japonicus (Theobald, 1901) controversial. In this work, we elucidated dynamics growth invasive mosquito species. Females Ae. were reared from eggs collected field Switzerland fed on bovine blood spiked with two WNV lineage 1 strains (FIN, Italy; NY99, USA). Fully engorged females incubated for 14 days under a fluctuating temperature regime 24 ± 7 °C (average °C),...
Nosema ceranae is the most widespread microsporidian species which infects honey bees of Apis mellifera by causing weakening their colonies and a decline in productive reproductive capacities. The only registered product for its control antibiotic fumagillin; however, European Union, there no formulation use beekeeping. Thymol (3-hydroxy-p-cymene) natural essential-oil ingredient derived from Thymus vulgaris, has been used Varroa decades. aim this study was to investigate effect thymol...
Among numerous factors that contribute to honey bee colony losses and problems in beekeeping, pesticides Nosema ceranae have been often reported. In contrast insecticides, whose effects on bees widely studied, fungicides did not attract considerable attention. Prochloraz, an imidazole fungicide used agriculture, was detected pollen stored inside hives has already proven alter immune gene expression of at different developmental stages. The aim this study simulate the realistic conditions...
Depending on the infection level and colony strength, Nosema ceranae, a microsporidian endoparasite of honey bee may have significant consequences health, reproduction productivity colonies. Despite exerting some side effects, fumagillin is most often used for control. In this study, in cage experiment, N. ceranae infected bees were treated with or extract Agaricus blazei mushroom, possible alternative Bee survival, spore loads, expression levels immune-related genes parameters oxidative...
Agaricus bisporus water crude extract was tested on honey bees for the first time. The part of cage experiment set selecting one concentration A. extract. Concentration 200 µg/g further in second where bee survival and food consumption were monitored together with Nosema infection level expression five genes (abaecin, hymenoptaecin, defensin, apidaecin, vitellogenin) that evaluated sampled days 7 15. Survival rate Nosema-infected significantly greater groups fed bisporus-enriched syrup...
First identified in 1947, Zika virus took roughly 70 years to cause a pandemic unusually associated with virus-induced brain damage newborns. is transmitted by mosquitoes, mainly Aedes aegypti, and secondarily, albopictus, both colonizing large strip encompassing tropical temperate regions. As part of the international project ZIKAlliance initiated 2016, 50 mosquito populations from six species collected 12 countries were experimentally infected different viruses. Here, we show that Ae....
Protection of honey bees is great economic importance because their role in pollination. Crucial steps towards this goal are epidemiological surveys pathogens connected with bee losses. In study deformed wing virus (DWV), chronic paralysis (CBPV), acute (ABPV) and sacbrood (SBV) were investigated colonies different strength located five regions Serbia. The relationship between colony occurrence/infection intensity assessed as well the genetic sequences from Serbia worldwide. Real-time RT-PCR...
Abstract Varroa destructor is the most important honey bee parasite. There are various methods used in control of this mite, but none them meets all requested criteria, to be safe, effective and easy apply. The objective study was evaluate varroacidal efficacy newly created plant-derived formulation Argus Ras (mixture extracts Sophora flavescens, Ginkgo biloba , Gleditsia chinensis Teucrium chamaedrys ) a field trial. investigation conducted on 240 Apis mellifera colonies equalized respect...
Abstract The most common types of beta-casein in cow’s milk are A1 and A2, which differ one amino acid. During the gastrointestinal proteolysis humans this difference results release beta-casomorphin-7, an opioid may lead to severe effects on human health, causing various ailments (type-1 diabetes mellitus, ischemic heart disease, arteriosclerosis, sudden infant death syndrome, autism, schizophrenia, digestive discomfort, as well increased transit time). By contrast, A2 cannot exert these...
To improve the genomic evaluation of milk-related traits in Holstein-Friesian (HF) cattle it is essential to identify associated candidate genes. Novel SNP-based analyses, such as genetic mapping inherited diseases, GWAS, and selection, have led a new era research. The aim this study was analyze association each individual SNP Serbian HF with milk production inbreeding levels. 60 K chip Axiom Bovine BovMDv3 deployed for genotyping 334 cows. obtained results, together collected phenotypic...
The honey bee is an important insect pollinator that provides critical pollination services for natural and agricultural systems worldwide. However, inadequate food weakens colonies, making them vulnerable to various biotic abiotic factors. In this study, we examined the impact of supplementary feeding on bees’ genes antioxidative enzymes vitellogenin, oxidative stress parameters, hygienic grooming behavior. colonies were divided into two experimental groups (with ten hives each): a...
Commercially and traditionally managed bees were compared for oxidative stress (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) malondialdehyde (MDA)), the prevalence of parasites (
Abstract The hygienic behavior in honey bees is a complex polygenic trait that serves as natural defense mechanism against bacterial and fungal brood diseases Varroa destructor mites infesting cells. aim of this study was to evaluate the effect dietary amino acids vitamins supplement “BEEWELL AminoPlus” on Apis mellifera colonies combating microsporidial viral infections. experiment performed during one-year period 40 alloted five groups: one supplemented infected with Nosema ceranae four...
Abstract Honey bee mite Varroa destructor and microsporidium Nosema ceranae are currently considered the most important threats to honey bees beekeeping. It has been believed that both N. apis invade exclusively epithelial cells of ventriculus. However, some fi ndings suggest these microsporidia may infect other tissues bees. There indications pathogens could be found in haemolymph, as medium for its distribution anatomically distant tissues. Knowing V. being an ectoparasitic feeds on bee’s...
The influence of various diets on the quality Apis mellifera queens was assessed. Colonies intended for queen cell production were assigned to four groups fed (1) sugar-only, (2) mix sugar, honey and fresh pollen, (3) sugar pollen substitute (FeedBee®), (4) natural sources. In addition, a fifth group had cells obtained naturally, by swarming. Sugar-only diet exerted significant (p < 0.05) stimulating effect acceptance weight newly emerged queens, not affecting mated queens. Among those...
