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. Some use surgical or methylated spirits, but see earlier comment. Click the button below to add the Thymol Crystals Bulk to your wish list. The information is published here is a matter of public record. 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. Both solid and liquid thymol can pass to the gaseous stage, which is necessary to reach the, When it is correctly used, thymol is a highly efficient and safe treatment against the, CATCH THE BUZZ- Honey Bees, Early to Bed, Early to Rise, CATCH THE BUZZ- Gut Bacteria Key to Honey Bee ID, CATCH THE BUZZ – Scientist Find Clues to Queen Bee Failure. Thymol crystals have three distinct uses in beekeeping, these being:-Prevention of mould and fermentation. 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). It remained under 4µg/l hive air, which explains the only low efficacy on cooler sites. Therefore, the duration of the treatment and any other indications given on the label are important to get the best results. The ideal range for thymol treatments is 20-25°C (68-77°F). Put jar into a water bath of boiling water to speed up the dissolving process. Thymol is also used as a rapidly degrading, non-persisting pesticide. The most widely used and popular products all over Europe with thymol as a main ingredient are: Apiguard, ApiLifeVar and Thymovar. The concentration in the hive air must be high enough to kill the, From all three products, ApiLifeVar was the most independent from environmental conditions. Comparison of the three products under different environmental conditions. 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. The other two products did not have this problem. This increases storage life and In the North, however, Apiguard was less reliable. Choose a currency below to display product prices in the selected currency. Thymovar and ApiLifeVar in this short period already killed 30-35% of the mites in Italy and 30-40% in Germany. In addition to the final efficacy, both studies measured the course of the efficacy during the treatment period, i.e. Thymol is administered in a number of ways, including proprietary products and slow evaporation. When it is correctly used, thymol is a highly efficient and safe treatment against the Varroa mite. 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. when it becomes liquid). how fast the products kill most of the mites. This is by increasing the concentration of thymol in syrup above the amount required to prevent mould and fermentation. Interestingly, the hive air concentration decreased during this week in treatments with Thymovar, while it slightly increased using ApiLifeVar.

In Germany, the same occurred: all three products were tested in Hesse (with cooler climate) and in the Rhine region (with milder climate). Thymol is a natural substance, but as every medicinal or pesticide product, it has to be handled with care and responsibly. In the Italian study, Thymovar in addition also showed some problems in tolerability: the bees removed brood and honey from beneath the strips. Mixing thymol with other aromatic substances decreases its melting point (i.e. Mixing thymol with other aromatic substances decreases its melting point (i.e. when it becomes liquid). The bee institute in Liebefeld (Switzerland) compared Thymovar and ApiLifeVar, finding high and similar efficacy for both products (around 90%). An interesting property of this blend is that it remains liquid at colder temperatures. Pure thymol is solid until a temperature of 49-51°C (105-124°F), therefore also under hive conditions of 35°C (95°F). It has long been known that thymolised syrup prevents the forming of mould and fermentation. 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. The efficacy remained over 90% at all sites. Sitemap | This increases storage life and reduces the chance of dysentery during the winter when bees are confined. or may not be approved in your geographic State or Country. ApiLifeVar is a blend of thymol with eucalyptol, menthol and camphor, while Apiguard and Thymovar rely on pure thymol. 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. Method of Application: Thymol has been applied to beehives world wide by various methods; strip, crystal, powdered and liquid Thymol are used. I neither endorse nor condemn this product. Pure thymol is solid until a temperature of 49-51°C (105-124°F), therefore also under hive conditions of 35°C (95°F). Harmful if swallowed, inhaled or absorbed through the skin. 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. Only these products were tested under different conditions and provide the data to make informed decisions about the right product to use. 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). At one of the two apiaries in this region, the study had to be interrupted because of the severity of the effects. An interesting property of this blend is that it remains liquid at colder temperatures. reduces the chance of dysentery during the winter when bees are confined. This antibacterial activity is caused by inhibiting growth and lactate production, and by decreasing cellular glucose uptake. Thymol is one of the alternative treatments in late Summer, or even in Spring according to the temperatures of the year or area. Thymovar worked better, though also this product was less efficient at the cooler site in Hesse. Add 5ml of isopropyl alcohol to the crystals. Eye, skin and respiratory irritant. 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. Not many studies are available comparing the three products by means of their efficacy under different environmental conditions. 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. The efficacy remained over 90% at all sites. 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. The details given above however show that a variety of factors influence the efficacy. The information is By this, the gel surface dried, impeding the evaporation. 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. Thymol—named after the herb itself—is the primary volatile oil constituent of thyme, and its health-supporting effects are well documented. 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. ApiLifeVar finally, was equally efficient at all sites and no problem with the safety for the bees happened. 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. It has long been known that thymolised syrup prevents the forming of mould and fermentation. Further information on all of the above can be accessed by the buttons on the top left. As already mentioned, this substance acts by its vapors. Manley. Again, under the warm conditions in Central and Southern Italy, all three products reached many mites already in the first week.
