Varroa destructor is an effective vector of Israeli acute paralysis virus in the honeybee, Apis mellifera.
The Israeli acute paralysis virus (IAPV) is a significant marker of honeybee colony collapse disorder (CCD). In the present work, we provide the first evidence that Varroa destructor is IAPV replication-competent and capable of vectoring IAPV in honeybees. The honeybees became infected with IAPV after exposure to Varroa mites that carried the virus. The copy number of IAPV in bees was positivel...
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...

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 کاملGene expression in honey bee (Apis mellifera) larvae exposed to pesticides and Varroa mites (Varroa destructor).
Honey bee (Apis mellifera) larvae reared in vitro were exposed to one of nine pesticides and/or were challenged with the parasitic mite, Varroa destructor. Total RNA was extracted from individual larvae and first strand cDNAs were generated. Gene-expression changes in larvae were measured using quantitative PCR (qPCR) targeting transcripts for pathogens and genes involved in physiological proce...
متن کاملHost Specificity in the Honeybee Parasitic Mite, Varroa spp. in Apis mellifera and Apis cerana
The ectoparasitic mite Varroa destructor is a major global threat to the Western honeybee Apis mellifera. This mite was originally a parasite of A. cerana in Asia but managed to spill over into colonies of A. mellifera which had been introduced to this continent for honey production. To date, only two almost clonal types of V. destructor from Korea and Japan have been detected in A. mellifera c...
