Aspects of the disclosure relate generally to controlling parasites. More specifically, aspects of the disclosure relate to controlling parasites by providing hosts with one or more compounds that reduce or eliminate parasite populations.
The Varroa destructor mite (also known as the Varroa destructor and the Varroa mite) is an external parasitic mite that attacks and feeds on various honey bees including the Apis cerana (the Asian honey bee) and Apis mellifera (the western honey bee). The disease caused by the mites is called varroosis. The Varroa mite can reproduce only in a honey bee colony. It attaches to the body of the bee and weakens the bee by sucking fat bodies. The Varroa destructor species is a vector for at least five debilitating bee viruses, including RNA viruses such as the deformed wing virus (DWV). A significant mite infestation often leads to the death of a honey bee colony, usually in the late autumn through early spring. The Varroa mite is the parasite with possibly the most pronounced economic impact on the beekeeping industry. Varroa is considered to be one of multiple stress factors contributing to the higher levels of bee losses around the world.
Aspects described herein may address these and other problems, and generally reduce issues associated with mite infestations in bee colonies. The following presents a simplified summary of various aspects described herein. This summary is not an extensive overview and is not intended to identify key or critical elements or to delineate the scope of the claims. The following summary merely presents some concepts in a simplified form as an introductory prelude to the more detailed description provided below.
Aspects described herein may allow for an improved composition of ingredients to help reduce or eliminate mite infestations in bee colonies. An artificial bee pollen patty (or cake) may be formulated with Artemisia as an anti-parasitical ingredient. In some aspects, the Artemisia is allowed to infuse into water and then filtered out. In other aspects, the Artemisia is combined into the patty with other ingredients.
These features, along with many others, are discussed in greater detail below.
The present disclosure is illustrated by way of example and not limited to the accompanying figures in which like reference numerals indicate similar elements and in which:
Various aspects relate to the creation of an artificial bee pollen patty with sugars and Artemisia (commonly known as wormwood). As described herein, two species of Artemisia are described herein (Artemisia annua and Artemisia afra). Other species of Artemisia having anti-parasitic compounds may be used in addition to Artemisia annua and/or Artemisia afra or in lieu of Artemisia annua and Artemisia afra. Other aspects relate to creating an artificial nectar with Artemisia annua and/or Artemisia afra. The difference in weight between bees and parasitic mites may be used to adjust the concentration of Artemisia in an artificial pollen patty and/or in the artificial nectar. For instance, if Artemisia is toxic to bees at a concentration greater than or equal to 88 mg/kg and a bee weighs, on average, 0.11 g to 0.2 g, then bee toxicity would range from 0.00968 mg to 0.0176 mg. Keeping the concentration of Artemisia between 10 to 20 mg/kg (one-eighth to one-quarter of bee toxicity) is desired.
As described here, a patty or cake is designed to rid the colony of mites in the brood cells. The patty is made available outside a hive for worker bees. The worker bees feed on the patty (full of protein and sugar and infused with Artemisia) and in turn, feed the bee larva by filling the brood cell with this food. As such, the patty is designed to address the issue of mites in the brood cell.
Also, another embodiment relates to a nectar comprised of one or more sugars infused with Artemisia. The nectar is intended to be ingested by workers, drones, and queen bees as food to kill the Varroa mite that is attached to them. The nectar-related embodiment may be beneficial in preventing the mites from attaching to them. The nectar is specifically designed to treat the mature bees in the colony.
In the following description of the various embodiments, reference is made to the accompanying drawings, which form a part hereof, and which are shown by way of illustration of various embodiments in which aspects of the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present disclosure. Aspects of the disclosure are capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. Rather, the phrases and terms used herein are to be given their broadest interpretation and meaning. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
By way of introduction, aspects discussed herein may relate to methods and techniques for providing an artificial bee pollen patty and/or nectar with sugars and Artemisia. The sugar may be used to attract bees. The Artemisia is ingested by the bee and functions as a miticide to eradicate the mites that may be on or in the bee and/or in the bee colony. The consumption of the Artemisia may provide three antiparasitic benefits to bees.
A first benefit may include direct coating of its mouth and digestive components with Artemisia. To the extent that any mites are in or around the mouth of the bees, the Artemisia may be concentrated in those areas and increase the exposure of mites to the Artemisia.
A second benefit may include the ingestion of the Artemisia and eventual storage in the bee's fat cells. To the extent that the mites attempt to feed off the bee's fat cells, the mites would have exposure to the Artemisia at a higher concentration than that experienced by the bee. If the Artemisia is in the fat cells, the Artemisia may prevent the mite from attaching at all.
A third benefit may include how bees feed bee larvae. As adult bees feed bee larvae by regurgitating food, the food may be mixed with Artemisia and fed directly to the larva. Mites may be capped in the brood comb with the bee larva, attach to, and feed off the bee larva. To the extent bees cap the brood comb with beeswax, the beeswax may contain residual amounts of Artemisia as well as any other material used to form or line the cocoons or food placed within the cocoons. Allowing sufficient Artemisia to be placed into the brood comb may kill the mites or prevent the mites from attaching to the bee larva. As such, any mites present in the hive may be controlled by residual Artemisia from outside the hive.
Further, there is also a possibility that the Artemisia may modulate the bee's pheromones to the extent that they would be less of an attractant to mites.
A process for forming the artificial bee pollen patty 101 may include the steps shown in
In step 203, the mixture is allowed to cool. Once this simple syrup is made the Artemisia is allowed to soak and infuse the syrup. The percentage of Artemisia is adjusted for the purpose of killing the Varroa mite but protecting the honey bee from toxicity. The percentage of Artemisia may be adjusted in the final product from 0.025% to 40% as needed. The anatomy of the bee will allow the absorption of the sugar molecules during normal digestion. Similarly, the antiviral properties of Artemisia may further protect bees from viral infections brought into a hive via Varroa mites. The Varroa mites find the bees through the detection of the bees' pheromones. There is an opportunity to further prevent mites from attaching to bees and/or entering a hive by masking or disrupting the mites' sensory attraction to bees.
In step 204, the Artemisia is added to the water/sugar solution. The Artemisia added in step 204 may include leaves and/or twigs in their natural state or having been ground into a powder to increase their surface area. In step 205, the Artemisia is allowed to infuse into the water over a period of time (e.g., 24-48 hours or longer). In step 206, protein and lipids may be added to the infused solution. In step 207, the pH of the mixture may be checked and adjusted with an acid (e.g., citric acid or other acid) to around 7 pH (e.g., within a range of 6.0 pH to 7.5 pH or 6.9 pH to 7.1 pH, for instance). In step 208, the compound is shaped into a patty and allowed to dry.
