Development of Varroa jacobsoni in colonies of Apis mellifera capensis and Apis mellifera carnica
Honey bee colonies (Apis mellifera carnical, infested with Varroa jacobsonl were de-queened and divided into 2 subunits. Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen. The development of the mite population was monitored by determining the number of mites in samples of brood, and worker bees, and lhe number of dead mites on the bottom board of the h...
متن کاملA population model for the ectoparasitic mite Varroa jacobsoni in honey bee (Apis mellifera) colonies
The ectoparasitic mite Varroa jacobsoni Oud. presently poses one of the most serious problems faced by keepers of honeybees Apis mellifera L. To help understand why the mite has become such a serious problem a population dynamics model using recently published data has been constructed. The simulation model has been built by linking together various aspects of the mites’ biology using computer ...
متن کاملPractical sampling plans for Varroa destructor (Acari: Varroidae) in Apis mellifera (Hymenoptera: Apidae) colonies and apiaries.
The parasitic mite Varroa destructor Anderson & Trueman (Acari: Varroidae) is arguably the most detrimental pest of the European-derived honey bee, Apis mellifera L. Unfortunately, beekeepers lack a standardized sampling plan to make informed treatment decisions. Based on data from 31 commercial apiaries, we developed sampling plans for use by beekeepers and researchers to estimate the density ...
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 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...
