Behavioral defenses of honey bees against Varroa jacobsoni Oud . Otto
Two behaviors of honey bees, hygienic behavior and grooming, are mechanisms of defense against brood diseases and parasitic mites. Studies have shown that Apis mellifera colonies remove worker brood infested with Varroa jacobsoni mites from the nest (hygienic behavior), and groom the mites off other adult bees, but to a limited extent compared to the original host of V. jacobsoni, A. cerana. Re...
متن کاملThe transmission of deformed wing virus between honeybees (Apis mellifera L.) by the ectoparasitic mite varroa jacobsoni Oud
Under field conditions, Varroa jacobsoni were shown to be highly effective vectors of deformed wing virus (DWV) between bees. Adult female mites obtained from honeybee pupae naturally infected with DWV contained virus titers many times in excess of those found in their hosts and, beyond that, which might be expected from a concentration effect. It is therefore possible that DWV may be capable o...
متن کاملVarroa - 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 کاملImpact of Varroa Mite
Varroa mite infestation was first detected in Iraq in the mid 1980s (Food and Agriculture Organization). High level of the infestation was found in all apiaries of Dohuk region and may act as a risk factor to the bee health. The mite V. destructor feeds on the haemolymph of the developing and adult bees. The structures that may be directly affected by Varroa mite infestation are the bee glands....

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...
