Feral honey bee populations have been reported to be in decline due to the spread of Varroa destructor, an ectoparasitic mite that when left uncontrolled leads to virus build-up and colony death. While pests and diseases are known causes of large-scale managed honey bee colony losses, no studies to date have considered the wider pathogen burden in feral colonies, primarily due to the difficulty...
The potential impact of varroa (Varroa destructor, Anderson & Trueman) on Australian beekeeping and agriculture depends in part on the levels of resistance to this parasite expressed by Australian commercial honeybees (Apis mellifera). The responses of seven lines of Australian honeybees to V. destructor were compared with the responses of a stock of Italian honeybees from the United States kno...
Varroa destructor is a well-known ectoparasite of the honey bee Apis mellifera. Amitraz and fluvalinate are highly effective miticides used against V. infestation in colonies A. Though bees more resistant to miticides, there side effects these chemicals on reproduction, olfaction, production bees. We showed negative impact amitraz reproduction colonies. Also, we assumed reduction olfaction by d...
The beekeeping sector is facing many challenges. One of the greatest maintaining healthy colonies that produce high-quality products without any residues veterinary medicines and with low environmental impact. main enemy ectoparasitic mite Varroa destructor, most significant honeybee pest a key factor in high colony losses worldwide. In previous four decades, three pillars control have crystall...
Voltage-gated sodium channels are essential for the generation and propagation of action potentials in most excitable cells. They are the target sites of several classes of insecticides and acaricides. Isolation of full-length sodium channel cDNA is a critical and often difficult step toward an understanding of insecticide and acaricide resistance. We previously cloned and sequenced two overlap...
