چکیده
Figure 1.—The three inhabitants of the hive: A, The ^vorker, a female with arrested development of the egg-laying organs; B, the queen, a female with completely developed egg-laying organs but with undeveloped secondary sexual characters such as those possessed by the worker for secreting larval food, for gathering nectar and pollen, for secreting wax, and the like; C, the drone, the male bee. During the height of the season, a bee colony may consist of several thousand workers and a few Inuidred drones, but it normally contains only one queen at any time.

Prevalence of Four Common Bee RNA Viruses in Eastern Bee Populations in Yunnan Province, China
Deformed wing virus (DWV), black queen cell virus (BQCV), sacbrood virus (SBV), Kashmir bee virus (KBV), acute bee paralysis virus (ABPV) and chronic bee paralysis virus (CBPV) are the most common RNA viruses in bee population worldwide. To determine the prevalence of these viruses in Apis cerana in Yunnan Province, China, 270 adult Eastern worker bee (A. cerana) samples have been collected fro...
متن کاملAn analysis of the energetic reward offered by field bean (Vicia faba) flowers: Nectar, pollen, and operative force
Global consumption of crops with a yield that is dependent on animal pollinators is growing, with greater areas planted each year. However, the floral traits that influence pollinator visitation are not usually the focus of breeding programmes, and therefore, it is likely that yield improvements may be made by optimizing floral traits to enhance pollinator visitation rates. We investigated the ...
متن کاملThe power and promise of applying genomics to honey bee health.
New genomic tools and resources are now being used to both understand honey bee health and develop tools to better manage it. Here, we describe the use of genomic approaches to identify and characterize bee parasites and pathogens, examine interactions among these parasites and pathogens, between them and their bee hosts, and to identify genetic markers for improved breeding of more resilient b...
متن کاملIn Vitro Infection of Pupae with Israeli Acute Paralysis Virus Suggests Disturbance of Transcriptional Homeostasis in Honey Bees (Apis mellifera)
The ongoing decline of honey bee health worldwide is a serious economic and ecological concern. One major contributor to the decline are pathogens, including several honey bee viruses. However, information is limited on the biology of bee viruses and molecular interactions with their hosts. An experimental protocol to test these systems was developed, using injections of Israeli Acute Paralysis...
متن کاملThree QTL in the honey bee Apis mellifera L. suppress reproduction of the parasitic mite Varroa destructor
Varroa destructor is a highly virulent ectoparasitic mite of the honey bee Apis mellifera and a major cause of colony losses for global apiculture. Typically, chemical treatment is essential to control the parasite population in the honey bee colony. Nevertheless a few honey bee populations survive mite infestation without any treatment. We used one such Varroa mite tolerant honey bee lineage f...
