How to increase bees immunity to varroa? 


Best insight from top research papers

To increase bees' immunity to varroa, several strategies have been explored. One approach is to allow honey bee colonies to develop resistance or tolerance to the mite by leaving them untreated in isolated locations . Another method involves supplementing bee larvae's diet with l-Arginine or abscisic acid (ABA), which enhances the immune activation of granulocytes in response to wounding and injection of lipopolysaccharide (LPS) . Additionally, certain traits such as varroa sensitive hygiene (VSH) behavior have been studied for their involvement in acquired resistance to varroa mites . These strategies aim to enhance bees' fitness and ability to confront the threats posed by varroa mites and other stressors .

Was uv light used to kill varroa mites?5 answersUV light has been utilized as a method to control Varroa mites in bee colonies. Research has shown that UV radiation, specifically in the UVB and UVC range, can have a harmful effect on Varroa mites, impacting their physiological functions. Additionally, UVA radiation has been proven effective in eradicating murine mites, demonstrating the potential of UV light in pest control. While UV light has been explored for its pest control capabilities, other methods such as oxalic acid treatments have also been studied. Oxalic acid, when administered through various methods like trickling and vaporization, has shown good control over Varroa mites in central Italy, highlighting different approaches to mite management. Overall, UV light, along with other treatments like oxalic acid, presents promising avenues for combating Varroa mites in beekeeping practices.
What is the latest Bee breeding reseach for varroa resistance?4 answersBreeding efforts for varroa resistance in honeybees have focused on identifying traits that can be easily measured and have high heritability. Two promising traits for selection are suppressed mite reproduction (SMR) and recapping of infested cells (REC). High-throughput qPCR assays have been developed to genotype eight single-nucleotide variants associated with suppressed mite reproduction, allowing for marker-assisted selection in breeding programs. Hygienic behavior, specifically the ability to detect and remove Varroa-infested brood, has also been identified as a potential tool for predicting colony-level Varroa resistance. Bee infestation rate in summer, adjusted for natural mite fall in spring, is a suitable trait for selective breeding for Varroa resistance. However, the mite non-reproduction (MNR) trait, which is commonly used in field studies, has low repeatability and lacks correlation with other resistance traits, suggesting caution in its interpretation and use for selection.
What are the methods used to control Varroa?4 answersVarroa mite control methods include chemical treatments such as formic acid, oxalic acid, and synthetic compounds, as well as organic methods like powdered sugar and heat. Laboratory rearing systems have been developed to obtain mites of known age and life cycle for experimental purposes. Hyperthermia, the use of heat, has been shown to effectively control Varroa mites within an integrated pest management (IPM) approach. Beekeepers in Europe commonly use monitoring of Varroa infestations, drone brood removal, and various acid applications for Varroa control. Mathematical models have been used to study the dynamics of mite-infested honey bee colonies and evaluate mite-control strategies, highlighting the importance of factors such as queen bee egg laying rate and worker bee grooming behavior.
How to stimulate immune response invivo?5 answersTo stimulate an immune response in vivo, several approaches have been explored. One method is the use of magnetic hyperthermia (MH) with superparamagnetic iron oxide nanoparticles (SPIONs). Another approach involves the use of mesoporous silica (MS) nanospheres doped with Ca, Mg, and Zn, which have shown potential as cancer immunoadjuvants. Additionally, adjuvant RNA complexed to cationic lipid DOTAP has been found to induce a cytotoxic T cell and humoral response. Photodynamic treatment (PDT) using a PS coupled with folate receptor has also been shown to activate an anti-tumoral immune response. Finally, microbial stimuli and danger signals have been investigated for their ability to re-programme dendritic cells (DCs) and macrophages to an immuno-stimulatory phenotype, leading to enhanced anti-tumour responses.
What are the best foods to boost immunity?5 answersThe best foods to boost immunity include a variety of plants and fruits such as Curcuma longa, Withania somnifera, Phyllanthus emblica, Azadirachta indica, Panax ginseng, Rhododendron spiciferum, Caesalpinia bonducella, Tinospora cordifolia, Capparis zeylanica, Asparagus racemosus, Nelumbo nucifera, Arnica montana, Calendula officinalis, Echinacea purpurea, and Euphorbia tirucalli. Other foods that have been found to boost immunity include Nigella sativa (black seed) oil, silverberry, date, grape, Asphodelus aestivus, Rheum ribes, and carob. Additionally, a Mediterranean-style diet rich in essential fatty acids, fruits, vegetables, whole grains, nuts, and olive oil has been shown to increase immunity. Functional foods and nutraceuticals have also been found to have immune-boosting activities, with biological activities including antioxidant, anti-inflammatory, antimicrobial, and immunomodulatory effects. Therefore, incorporating these foods into the diet can help strengthen the immune system and promote overall health.
How to increase antibody or immune system to children with allergic?5 answersTo increase antibody or immune system response in children with allergies, several approaches can be considered. One approach is sublingual immunotherapy (SLIT), which has shown clinical improvement and modulation of mucosal/systemic antibody responses in allergic children. Another approach is to implement dietary and environmental control measures early to decrease sensitization and appropriately treat the signs and symptoms of allergic disease. Additionally, exposure to natural environments rich in species and beneficial protective microbes has been found to be strongly related to immunotolerance and immune development. Understanding the distinctive patterns of IgE production and cytokine synthesis during the development of allergic diseases can also provide insights into enhancing the immune response. Overall, a combination of targeted therapies, environmental control measures, and promoting contact with natural environments may help increase antibody or immune system response in children with allergies.
