I have the impression that, for most people, use your brain, in addition to basic vital functions, even to think and reason action is highly impractical. I firmly believe that the reproductive success of Varroa has three powerful allies beekeepers the foolishness, ignorance of the researchers, the interest of many who have played with varroa lucrative business.
control Varroa requires basic knowledge that can be briefly summarized as follows:
- knowledge of the life cycle of bees and compared the vaoora
- implementation of early diagnostic methods
- understood as the correct application, method and timing of the most popular on the market antivarroa
- application, even intermittently, physical control methods such as block brood, the removal of the male brood, and so on.
and finally
- application of space mussi
How is it that, faced with a arsenal of this kind, the mite continues to lord it, if the news is true, in large Part of the Italian farms?
Use wrong and what's more sequentially in the same apiary, acaricides of a different nature, has led to the emergence of cross-resistance to most common active ingredients to useless to them.
Experience on the fight against varroa, since 1979 (January 2011), leads me to say that no beekeeper will never be able to control the pest if acting in isolation and this is more true than ever with increasing densities of hives in the area, one of the open secrets is "to act in a coordinated manner within a regional control plan."
The development of a drug whether veterinary or human use of the following protocols that over the years to identify the activity of the active against the pathogen also its physiological mechanism of action. Knowing the mechanism of action is crucial to establish methods of administration, dosage, time of administration.
in the fight against varroa, bee-keepers in general, relying on an excess of self-esteem, have ventured in the application of economic solutions, not always effectiveness, and in the search for a solution capable of miraculous free of the varroa , often eschewing the pretext of reducing operating costs, duly registered and licensed products, but then, in the grip of desperation move in sequence from one to the atrium without respect of times and dosages.
This authentic madness was the main cause of the damage from varroa which are now visible to everyone.
The beauty of this whole story is that all the inventions that have been shown to be effective they also had endorsed a pseudo science that has, to some extent, promoted the use, someone remembers:
- amitraz administered microdiffusore
- strips of poplar fluvalinate
- thymol menthol mixture
- acids organic lactic, formic and oxalic then
Not to mention the methods of administration, an encyclopaedia.
Take for example the last case in chronological order sublimed oxalic acid. By adopting this method, all believe they are working against varroa oxalic acid as the active ingredient instead is not true. Sublimation is the direct change from solid to gas without passing from the liquid state. Well not sublimate all the oxalic acid at a temperature of 189.5 ° C decomposes producing carbon dioxide and formic acid, formic acid and it is acting against varroa, the smoke you see is largely due to ' water contained in the acid crystals that evaporate suddenly, like an explosion causes condensation and suffered as a result of the expansion and for contact with the air temperature considerably lower.
Does anyone remember that you have ever read, or be aware of scientific studies that investigate biological mechanisms of action of many antivarroa, common and recommended, such as organic acids and aromatic substances? And not knowing the mechanisms of action, on what basis are recommended dosages and methods of administration? Eye? Then it is justifiable, even if not shared, if beekeepers have made their personal recipes, the most serious aspect, however, is not the proliferation of recipes but the spread of the DIY mentality that, no doubt, is one of the causes of survival to the bitter end of the varroa.
