Use of natural products, especially nutraceuticals is gaining much importance in aquaculture practices for controlling the diseases, since they can be easily incorporated into the diet along with a low impact on the environment. Among many different nutraceuticals, propolis has drawn the attention of the researchers as it has several biological and pharmacological properties. Propolis is a dark-brown, resinous material collected by bees from exudates and buds of flowers, mixed with beeswax and β-gucosidase (Pietta et al., 2002). The word propolis (from Greek, pro = for or in defence, and polis = city) shows its importance to bees, since they use it to seal holes in the hives to protect the colony from infection and to cover carcasses of intruders who die inside the hive, avoiding their decomposition (Bankova et al., 2000 and Sforcin et al., 2011). Propolis has been used as medicine due to its diverse biological and pharmacological properties such as immunomodulatory, antitumor, antimicrobial, anti-inflammatory, antioxidant etc. (Bankova et al., 2000). Its chemical composition includes more than 200 constituents (Marcucci, 1995) for which its biological properties are diverse. Propolis generally consists of 50% vegetable balsams and resins, 30% wax, 10% essential oils, 5% pollen and 5% various other substances (Burdock, 1998). The major constituents of propolis are flavones, flavanones, cinnamic acid, diterpenic acid, polyprenylated benzophenones, caffeic acid esters,
Varroa mites originate from Asia were first introduced in America through Florida in the mid 1980’s. The Varroa mites are parasites which feed on the blood of bees. These mites transmit various diseases and viruses to the bee colonies that they infect. The also develop alongside bee larvae and lay their eggs in cells in the hive that contain developing baby bees. If left unchecked, these mites can easily take down whole colonies of bees. In order to counteract the effect of these mites, proper management of bee colonies must be present. By detecting the threat of mites early, they can be taken care of easily Apistan, a product that will take care of
The objective of this research is to gain knowledge and disseminate information in regards to the cultural practices in honey bee husbandry and the management of small hive beetles. The small hive beetle is known to be an occasional pest species to African honey bees, but they are more of a threat to European honey bees. The aim of this study is to investigate the potential effects of commercial pollen dough substitutes on the survivability and reproductive success of the small hive beetle. This new information will aid beekeepers through the process of selecting diets that are impactful in stopping the spread of SHB in honey bee colonies.
The best-known product is honey, yet the beekeeping sector is much wider and represents a relevant part of European agriculture. The other bees products we can find on the market are wax, propolis, royal jelly, pollen, and even poison that is used in cosmetics and pharmaceuticals. There is also an internal market for buying bees, queen bees, hives, and specific equipment. All these products generate revenue that guarantees economic benefits to a portion of agriculture.
According to the Centres for Disease Control and Prevention (CDC) a minimum of 2 million people become infected with antibiotic resistant bacteria and an estimated minimum of 23, 000 people die each year as a direct result of those infections . As an increasing number of infectious diseases are becoming resistant to numerous allopathic medicines , for example meticillin-resistant staphylococcus aureusis or MRSA, more research is being conducted into alternative treatments derived from naturally occurring substances. Having heard about the
The definition of aquaculture is simply the farming of fish, plants and shellfish as well as many more aquatic organisms. Aquaculture refers to the cultivation of freshwater and marine species, and includes land based and opens ocean production. Aquaculture can be compared with commercial fishing, aquaculture involves cultivating of fresh and saltwater populations under controlled conditions, while commercial fishing is the harvesting of wild aquatic creatures and can be seen more as a form of “hunting and gathering”.
An average bee colony produces 27.2-45.4 kg of honey each year. Colonies are grouped in a three-tier organization consisting of 50.000-70.000 workers, one queen, and 2.000 drones. Worker bees only live for three to six weeks, each one collecting about one teaspoon of nectar. One kilogram of honey requires 3.96kg of nectar, which requires approximately four and a half million flowers to collect. When worker bees are about 20 days old they leave the hive to collect nectar, the sweet recreation produced by flowers’ glands. Bees extract the liquid from various flowers using their long tube-shaped nose. The nectar is stored in bees’ extra stomach where the fluid is mixed with many enzymes which change nectar’s chemical composition and pH making
Rosonia, great post this week and you added some beneficial information for all the class. I have never really worked in a big company until recently so I can not give my insight on a reward system or their way of setting goals. I currently started doing some counseling services at Camelot Care Centers and they are a big organization. I have owned and operated my own business for fourteen years and I have set goals for my employees. We set down every month and discuss what has been accomplished, what needs to be accomplished, and how can we achieve these things within a decent time frame. To me and my business, it is important to have goals and reach them. This gives me and the employee's things to look forward to and how we can make the children’s
Biologists Antonina Rişcu and Marian Bura stand by the theory that pesticides play a large role in the endangerment of bee species in their article “The Impact Of Pesticides On Honey Bees And Hence On Humans.” The article includes other possible causes for the endangerment of bees, including parasites, disease, climate, and pesticides. However, the authors focus on the idea that beekeepers themselves could be poisoning the bees with the inappropriate use of pesticide products (Rişcu, 2013; Bura, 2013).
Thus, the approaches that we can take to showcase the beeswax and pollen from Ellie’s beehive are seemingly endless. Beeswax and or pollen have been used in everything from weight-loss drugs to firearms. Beeswax is a leading ingredient in many everyday products. Gummy bears, lip balm and candles are amongst the wide range of products that are made using beeswax. Although at a lesser degree than that of beeswax, there are also many products that are made from bee pollen. Bee pollen is often used in food or pill form and has been ascribed as a ‘miracle’ cure to a wide-variety of ailments. Bee pollen has been attributed to do many things, including increasing energy, curing addiction and solving fertility problems for women. Also, in recent years, it has became common for many a celebrity to attribute their weight-loss to bee pollen
The increase of fish meal and fish oil prices has urged aquaculture companies to use alternative ingredients for feed production. However, nutritional imbalances caused by the replacement of marine ingredients can reduce growth rates, and may also alter the immune response or reared fish. In this study we aimed to evaluate the effects of an extensive replacement of dietary fish meal and oil by plant and animal ingredients on the immune response of Atlantic salmon. During a 14-week trial, Atlantic salmon were fed a fish meal-fish oil based diet (FM), a diet based on plant protein and oil (VEG), and a vegetable oil-based diet with animal by-product meal as major protein source (ABP). At the end of the trial, salmon were injected with either phosphate-buffered
The Western Honey Bee can be severly hurt by Sacbroad, a disease caused by a virus, and Varroa mites (Moore, Wilson, et al). Western Honey Bees do tend to have medicinal purposes due to their ability to make honey. According to medical-dictionary.thefreedictionary.com, studies show that “since bees are as major cause of life-threatening anaphylaxis in sensitised individuals, homeopathy, a homeopathic remedy obtained from honey bees, can help treat bee stings and other insect bites, oedema, and other causes of burning and swelling, including cystitis, allergies and sore throat.” For commercial purposes, only A. mellifera and A. cerana have been used to gather honey. But, only A. mellifera has been used expansively for commercial pollination of plants and other crops. This honey helps consumers alleviate pain, allergies and naturally sweetens drinks. Honeybees have many adaptations for defense: Adults have orange and black striping that acts as warning coloration. Predators can learn to associate that pattern with a painful sting, and avoid them. Honeybees prefer to build their hives in protected cavities (small caves or tree hollows). They seal small openings with a mix of wax and resins called propolis, leaving only one small opening. Worker bees guard the entrance of the hive. They are able to recognize members of their colony by scent, and will attack any non-members that try to enter the
Environmentally safe?: Lora A. Morandin1 and Mark L. Winston found it was not safe for bees
Over the years as the population has grown the demand for food supply from the ocean has grown beyond the natural capacity of production. In attempt to produce more food as well as protect species from extinction caused by over fishing, the use of aquaculture began to multiply. Aquaculture seems like a reasonable solution to this problem as farms can produce mass amounts of food much faster than possible in the natural ocean ecosystem. However, there are problems with aquaculture, one major problem being disease and parasites that are being transferred within fish farms as well as into the wild fish population.
Material and methods; Capparis spinosa honey (1g/kg.b.wt), propolis (100 mg/kg.b.wt), honey/propolis mixture (100 mg/1g/kg.b.wt), distilled water (1 ml/kg.b.wt) and furosemide (10 mg/kg.b.wt) were orally administered to five groups of rats for 21 days. Urine volume, blood and urine sodium, potassium and chloride were measured. The antioxidant activity of propolis and the honey was assessed and their total phenols and flavonoids were determined.
Proteins and lipids play a crucial role in the individual`s survival and health. Bees can obtain these two macronutrients from most pollen sources, but in different ratio. Pollen protein and lipid concentrations vary from ∼2–60%
