In the fight against the bee parasite Varroa Destructor...there will be a new, easy and effective weapon to support state of the art therapies.The app "Varroa Counter" helps to early recognize critical mite live stock andto estimate optimal treatmentment points in time.The Varroa Counter is the worlds first professional mobile counting application forthe Varroa Destructor mite, a bee vermin causing serious problems in the last years.The abilities to count a whole hive tray per single button press and to esteem the affection are easing beemasters lifes.Due to mild winter temperatures caused by climate change the mites proliferate almost all-yearand the breed seasing is not ceaseing during winter. Thus critical damages to bee colonies are observed even before honey harvest. Classical therapies fail and cannot be applied in thistime window. With the provision of this smartphone app it becomes possible to count naturally perished mites withcomputer vision. Opposite to manual counting the time consumed is less, increasing working efficiency.A photo is made and an intelligent algorithm identifies and counts individual mites.If an action limit of dead mites is reached a recommedation to administer a therapy is made.This is realized by an integrated population model which estimates the overall mite population duebasis of natural mortalitiy rates.Without periodical counting of dead mites, which fall down into bins on bottom of bee hives, itis difficult to determine optimal points in time for counter measures.The mite population grows exponentionally and if bee masters treat too late thereare irreversible damages of bee colonies. This means less honey and less pollination in agriculture.In worst cases whole bee colonies are lost. The damages - direct and indirect - are considerable.
