Ultrastructure of the flight muscle of worker honey bees heavily infested by the tracheal mite Acarapis woodi

An Easy Dissection Technique for Finding the Tracheal Mite, Acarapis Woodi (rennie) (acari: Tarsonemidae), in Honey Bees, with Video Link*

Since the introduction of varroa mites (Varroa destructor Anderson and Trueman, 2000), the impact of tracheal mites on bees has been largely overshadowed or ignored. Tracheal mites are still present in bees, and may be responsible for some unexplained colony losses. If they cause bee mortality, it is important to be able to identify their presence and at what levels. This paper illustrates a qu...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

APICULTURE AND SOCIAL INSECTS Infestation of Tracheal Mites (Acari: Tarsonemidae) in Feral and Managed Colonies of Honey Bees (Hymenoptera: Apidae)

J. Econ. Entomol. 86(3): 712-714 (1993) ABSTRACT We tested a population dynamics model that predicts that swarming of honey bees, Apis mellifera L., is a regulatory process of tracheal mites, Acarapis woodi (Rennie), parasitism. If the model is correct, then feral colonies that are free to swarm should have fewer numbers of infested worker bees, infested workers should have fewer numbers of mit...
