Varroa - Bee Relationships – What They Tell Us about Controlling Varroa Mites on the European Honeybee
Until recently, only three species of Varroa mites had been recorded: Varroa jacobsoni, V. underwoodi and V. rindereri. Of these, V. jacobsoni had received the most attention from researchers, primarily because it was believed to have switched host from the Asian bee (Apis cerana) to the European honey bee (A. mellifera) some 40-50 years ago, then spread to become a serious parasite of A. melli...
متن کاملThe effect of temperature and humidity on grooming behaviour of honeybee, Apis mellifera (Hym.: Apidae) colonies against varroa mite, Varroa destructor (Acari: Varroidae)
رفتار نظافت‌گری یکی از مهم‌ترین مکانیزم‌های دفاعی زنبور عسل علیه کنه‌ی واروآ می‌باشد که در طرح‌های اصلاح‌نژادی برای بهبود این صفت تلاش می‌شود. علاوه بر خصوصیات ژنتیکی کلنی، شرایط محیطی نیز در بروز چنین صفات رفتاری مؤثر است. هدف این تحقیق، تعیین تأثیر دما و رطوبت نسبی روی رفتار نظافت‌گری کلنی‌های زنبور عسل علیه کنه‌ی واروآ در دو لاین مقاوم و حساس به این کنه بود. برای این منظور، صد زنبور عسل ک...
متن کاملCombating Varroa destructor in Honeybee Colonies Using Flumethrin or Fluvalinate
Gregorc A. , M. I . Smodi‰ ·kerl : Combating Varroa destructor in Honeybee Colonies Using Flumethrin or Fluvalinate. Acta Vet. Brno 2007, 76: 309-314. Mite mortality in two apiaries, one with 32 and the other with 15 honeybee (Apis mellifera carnica) colonies, was recorded prior to and after flumethrin or fluvalinate treatments and after a control, oxalic-acid application. During the 42and 51-d...
متن کاملPropolis chemical composition and honeybee resistance against Varroa destructor.
Propolis is known as honeybee chemical defence against infections and parasites. Its chemical composition is variable and depends on the specificity of the local flora. However, there are no data concerning the relationship between propolis chemical composition and honeybee colony health. We tried to answer this question, studying the chemical composition of propolis of bee colonies from an api...
متن کاملA selective sweep in a Varroa destructor resistant honeybee (Apis mellifera) population.
The mite Varroa destructor is one of the most dangerous parasites of the Western honeybee (Apis mellifera) causing enormous colony losses worldwide. Various chemical treatments for the control of the Varroa mite are currently in use, which, however, lead to residues in bee products and often to resistance in mites. This facilitated the exploration of alternative treatment methods and breeding f...
