thymol crystals for bees
Mixing thymol with other aromatic substances decreases its melting point (i.e. When it is correctly used, thymol is a highly efficient and safe treatment against the Varroa mite. Apiguard in this trial had the lowest efficacy on both sites, with 43.1% in Hesse and 71.5% in the Rhine region. Thymovar and ApiLifeVar in this short period already killed 30-35% of the mites in Italy and 30-40% in Germany. Eye contact Method of Application: Thymol has been applied to beehives world wide by various methods; strip, crystal, powdered and liquid Thymol are used. Thymol (also known as 2-isopropyl-5-methylphenol, IPMP) is a natural monoterpene phenol derivative of cymene, C10H14O, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris (common thyme) and various other kinds of plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. This may be due to the different composition of this product: differently to the other two, it is a blend of thymol with menthol, eucalyptol and camphor. The researchers attributed this low efficacy to the lower temperatures and low activity of the bees: under these circumstances, the workers did not “work” on the gel to remove it.

The ideal range for thymol treatments is 20-25°C (68-77°F). how fast the products kill most of the mites. may cause serious harm. Odor Description: Thymol has a sharp, clean odor reminiscent of Thyme Essential Oil.Appearance: White to slightly yellow crystals.Soluble In: Alcohol and Oils.Insoluble In: Water and DPGFlash Point: 93deg CCRC Kosher Certified.

It is important to note that thymol does not reach reproducing Varroa mites in the brood and only kill the mites on the adult bees. Pure thymol is solid until a temperature of 49-51°C (105-124°F), therefore also under hive conditions of 35°C (95°F). The most widely used and popular products all over Europe with thymol as a main ingredient are: Apiguard, ApiLifeVar and Thymovar. Only these products were tested under different conditions and provide the data to make informed decisions about the right product to use. Mixing thymol with other aromatic substances decreases its melting point (i.e. This may have been due to a higher dose of thymol in Thymovar than in the other products and may have been released too fast. Therefore, the duration of the treatment and any other indications given on the label are important to get the best results. This increases storage life and In the table below, you can find a summary of the results of these studies. Pure thymol is solid until a temperature of 49-51°C (105-124°F), therefore also under hive conditions of 35°C (95°F).

Add 5ml of isopropyl alcohol to the crystals.

Comparison of the three products under different environmental conditions. Thymol has antimicrobial activity because of its phenolic structure, and has shown antibacterial activity against bacterial strains including Aeromoans hydrophila and Staphylococcus aureus. Thymol has been used in alcohol solutions and in dusting powders for the treatment of tinea or ringworm infections, and was used in the United States to treat hookworm infections. However, the step from liquid to gaseous (evaporation) is much more constant and reliable than the step from solid to gaseous (sublimation), especially under cooler temperatures. In the North, however, Apiguard was less reliable. Add 1 … This increases storage life and reduces the chance of dysentery during the winter when bees are confined. It is also used as a preservative in halothane, an anaesthetic, and as an antiseptic in mouthwash. The other two products did not have this problem. Put 30g thymol crystals in a clean honey jar. Not intended for internal use. However, these products are not exactly the same: Apiguard is a gel with thymol, while the other two products are strips saturated with it. Tests in Switzerland showed that Apiguard, under cooler conditions, did not reach this therapeutic concentration. Again, under the warm conditions in Central and Southern Italy, all three products reached many mites already in the first week.

In Northern Italy, the colonies decreased significantly in strength. It has long been known that thymolised syrup prevents the forming of mould and fermentation. Sitemap | When used to reduce plaque and gingivitis, thymol has been found to be more effective when used in combination with chlorhexidine than when used purely by itself.

Like formic acid, thymol acts by its vapors. This antibacterial activity is caused by inhibiting growth and lactate production, and by decreasing cellular glucose uptake. As already mentioned, this substance acts by its vapors. In addition, the external temperature is important: the efficacy is highest when the temperature ranges between 15-30°C (59-86°F) and never falls under 12°C (54°F).

ApiLifeVar is a blend of thymol with eucalyptol, menthol and camphor, while Apiguard and Thymovar rely on pure thymol. Under the cooler conditions in Northern Italy and Germany though, Apiguard started only very slow and killed only about 10% of the, In this context, it is important to understand the conditions for treatment success with thymol. For having best results by using thymol, some background knowledge is useful. In this context, it is important to understand the conditions for treatment success with thymol. In studies on aging in rats, thymol has been found to protect and significantly increase the percentage of healthy fats found in cell membranes and other cell structures.Thyme also contains a variety of flavonoids, including apigenin, naringenin, luteolin, and thymonin. An interesting property of this blend is that it remains liquid at colder temperatures. Other preparations do not offer this security: they may not have sufficient efficacy or the thymol concentrations in the hive air may get too high and harm the bees.

The bee institute in Liebefeld (Switzerland) compared Thymovar and ApiLifeVar, finding high and similar efficacy for both products (around 90%). The efficacy remained over 90% at all sites. Therefore, it is crucial to use registered products for Varroa treatments. Further information on all of the above can be accessed by the buttons on the top left. In the Centre and the South, all three products showed high efficacy, killing more than 90% of the, In addition to the final efficacy, both studies measured the course of the efficacy during the treatment period, i.e. Interestingly, the hive air concentration decreased during this week in treatments with Thymovar, while it slightly increased using ApiLifeVar.

Copyright 2020 myworldhut. Eye, skin and respiratory irritant. Product characteristics influence efficacy. The bees distribute them in the hive by their activity, like ventilation or removal of the product. Thymol has been used to successfully control varroa mites and prevent fermentation and the growth of mold in bee colonies, methods developed by beekeeper R.O.B. Thymol crystals have three distinct uses in beekeeping, these being:-. This may be the explanation for the more consistently high efficacy of ApiLifeVar under cooler climatic conditions. when it becomes liquid). A first extensive comparison of all three products was made in Italy: the scientists performed a study at three different locations in Northern, Central and Southern Italy. Handle with care and use suitable protective clothing.

Harmful if swallowed, inhaled or absorbed through the skin. Thymol also provides the distinctive, strong flavor of the culinary herb thyme.

At one of the two apiaries in this region, the study had to be interrupted because of the severity of the effects. By this, the gel surface dried, impeding the evaporation.

The information is published here is a matter of public record. reduces the chance of dysentery during the winter when bees are confined. when it becomes liquid).

Thymol is also the active antiseptic ingredient in some toothpastes, such as Euthymol.There is evidence supporting the belief that thymol, when applied two to three times daily, can eliminate certain kinds of fungal infections that affect fingernails and toenails. In Germany, the same occurred: all three products were tested in Hesse (with cooler climate) and in the Rhine region (with milder climate). The concentration in the hive air must be high enough to kill the Varroa mites, but low enough not to harm the bees. European beekeepers use thymol for several years, having three different registered treatments.

These flavonoids increase thyme's antioxidant capacity, and combined with its status as a very good source of manganese, give thyme a high standing on the list of anti-oxidant foods. Thymovar worked better, though also this product was less efficient at the cooler site in Hesse. when it becomes liquid). In the Centre and the South, all three products showed high efficacy, killing more than 90% of the Varroa mites in the colonies. It remained under 4µg/l hive air, which explains the only low efficacy on cooler sites.

As already mentioned, this substance acts by its vapors. The efficacy dropped to 66.9%, which is insufficient for protecting bee colonies until the Winter treatment. In the Italian study, Thymovar in addition also showed some problems in tolerability: the bees removed brood and honey from beneath the strips. Thymol is one of the alternative treatments in late Summer, or even in Spring according to the temperatures of the year or area. Under the cooler conditions in Northern Italy and Germany though, Apiguard started only very slow and killed only about 10% of the Varroa mites within the first week of the treatment. In addition to the final efficacy, both studies measured the course of the efficacy during the treatment period, i.e.
