The genus Serratia harbors opportunistic pathogenic species, among which marcescens is for honeybees although little studied. Recently, virulent strains of S. colonizing the Varroa destructor mite’s mouth were found vectored into honeybee body, leading to septicemia and death. also occurs as an pathogen in honeybee’s gut with a low absolute abundance. population seems controlled by host immune system, but its presence may represent hidden threat, ready arise when are weakened biotic abiotic...
Nosema ceranae is a widespread microsporidium of European honeybee Apis mellifera L. affecting bee health. The ban Fumagillin-B (dicyclohexylammonium salt) in the Union has driven search for sustainable strategies to prevent and control infection. gut microbial symbionts, associated intestinal system vertebrates invertebrates its impact on host health, are receiving increasing attention. In particular, bifidobacteria lactobacilli, which normal inhabitants digestive bees, known protect their...
Honey bees are important pollinators of several crops and ecosystems, having a great ecological economic value. In Europe, the restricted use chemicals therapeutic agents in beekeeping sector has stimulated search for natural alternatives with special focus on gut symbionts. The modulation microbiota been recognised as practical successful approach entomological field management insect-related problems. To date, only few studies have investigated effect bacterial supplementation health...
Pollinators, including solitary bees, are drastically declining worldwide. Among the factors contributing to this decline, bee pathogens and different land uses of relevance. The link between gut microbiome composition host health has been recently studied for social pollinators (e.g. honeybees), whereas information related bees is sparse. This work aimed at characterization Xylocopa augusti, Eucera fervens Lasioglossum attempted correlate microbial with presence load uses. Solitary were...
Abstract The research aims to give new insights on the effect of administering selected bacterial strains, isolated from honey bee gut, and/or a commercial plant extract blend (HiveAlive ® ) Nosema ceranae . Analyses were first performed under laboratory conditions such as different infective doses N. , single strains and their mixture influence pollen administration. Daily survival feed consumption rate recorded pathogen development was analysed using qPCR microscope counts. Biomarkers...
Fungicides, insecticides and herbicides are widely used in agriculture to counteract pathogens pests. Several of these molecules toxic non-target organisms such as pollinators their lethal dose can be lowered if applied a mixture. They cause large unpredictable problems, spanning from behavioural changes alterations the gut. The present work aimed at understanding synergistic effects on honeybees combined in-hive exposure sub-lethal doses insecticide thiacloprid fungicide penconazole. A...
Several studies have outlined that a balanced gut microbiota offers metabolic and protective functions supporting honeybee health performance. The present work contributes to increasing knowledge on the impact of three most common veterinary drugs (oxytetracycline, sulfonamides, tylosin). study was designed with semi-field approach in micro-hives containing about 500 honeybees. Micro-hives were located an incubator during day moved outdoors late afternoon, considering restrictions use...
Several studies have outlined that changes in the honeybee gut microbial composition may impair important metabolic functions supporting honeybees' life. Gut dysbiosis be caused by diseases like Nosema ceranae or other anthropic, environmental experimental stressors. The present work contributes to increasing knowledge on dynamics of microbiome acquisition caged honeybees, an condition frequently adopted researchers, with without infection N. ceranae, and fed a bacterial mixture control...
Nosema ceranae is a major pathogen in the beekeeping sector, responsible for nosemosis. This disease hard to manage since its symptomatology masked until strong collapse of colony population occurs. Conversely, no medicaments are available market counteract nosemosis, and only few feed additives, with claimed antifungal action, available. New solutions strongly required, especially based on natural methods alternative veterinary drugs that might develop resistance or pollute honey bees...
Apis mellifera evolved mainly in African, Asian, and European continents over thousands of years, leading to the selection a considerable number honey bees subspecies that have adapted various environments such as hot semi-desert zones cold temperate zones. With evolution bee subspecies, it is possible environmental conditions, food sources, microbial communities typical colonized areas shaped gut microbiota.In this study microbiota two distinct lineages (mitochondrial haplotypes) ruttneri...
Bombus pauloensis is a native bumble bee species widely distributed over South America and key pollinator for plants commercial crops. This affected by pathogens such as Nosema ceranae, Crithidia bombi Apis mellifera Filamentous Virus (AmFV). work aims to document the presence intensity of exogenous on B. in different periods year during spring summer. Bumble bees were sampled four study areas with contrasting land uses preliminary evaluate if anthropization levels can be related pathogens....
The role of a balanced gut microbiota to maintain health and prevent diseases is largely established in humans livestock. Conversely, honeybees, studies on perturbations by external factors have started only recently. Natural methods alternative chemical products preserve honeybee been proposed, but their effect the has not examined detail. This study aims investigate administration bacterial mixture bifidobacteria Lactobacillaceae commercial product HiveAliveTM microbiota. was developed 18...
Abstract Intensive conventional farm management, characterized by high agrochemicals input, could alter the composition of microbial communities with potential negative effects on both functional traits and ecosystem services provided. In this study, we investigated gut a ecological relevance carabid Pseudoophonus rufipes , sampled in two fields subjected to organic management practices. Carabids’ microbiota was analyzed via qPCR NGS. Profound differences between samples were detected:...
Pollen collected by pollinators can be used as a marker of the foraging behavior well indicate botanical species present in each environment. intake is essential for pollinators' health and survival. During activity, some pollinators, such honeybees, manipulate pollen mixing it with salivary secretions nectar (corbicular pollen) changing chemical profile. Different tools have been developed identification origin pollen, based on microscopy, spectrometry, or molecular markers. However, up to...
Soil respiration is a critical process that regulates key ecosystem functions such as climate control, nutrient cycling, and plant productivity. texture, availability, microbial communities can all influence soil respiration, yet our understanding of their relative importance remains limited. This study aimed to investigate how different factors—like additions, communities—contribute define specific roles in its variability. Using microcosm experiment with various fertilizers two types...
AbstractThe first occurrence of Leptus mites parasitizing different species stingless bees is reported. The samples were collected in the Argentinian province Misiones on flowers and managed bee colonies. Although frequency registered was very low, current report relevant as it will drive research efforts understanding parasite-host dynamics, consequences at community level, disease management wild productive contexts.Keywords: Argentinabee healthmiteswild Disclosure statementThe authors...
Abstract Several studies have outlined that a balanced gut microbiota offers metabolic and protective functions supporting honeybee health performances. The present work contributes to increasing knowledge on the impact of administration three different veterinary drugs (oxytetracicline, sulphonamides tylosin). trial was designed with semi-field approach in micro-hives containing about 500 bees, i.e. experimental conditions as close possible real hives considering restrictions use...
A pot experiment was carried out to evaluate the remediation potential of Brassica juncea and Sorghum bicolor in decontamination soil polluted with heavy metals such as copper, lead, tin, zinc along polychlorinated biphenyls, polycyclic aromatic hydrocarbons, hydrocarbons. Two composts obtained from different composting processes were tested biostimulating agents. At end trial, effect plant/compost combinations on microbial composition, contaminant removal, biochemical indicators, plant...
