Three haplotypes were identified among 470 colonies samples at 47 Japanese sites. All isolates from the main Japanese Islands of Honshu, Shikoku, and Kyushu belonged to a single haplotype, a previously reported Japan 1 haplotype. Two new haplotypes were found on the far southern Japanese islands of Amami-Oshima and Tsushima (the Japan 3 and Japan 4 haplotypes, respectively). -

Since the 1980s, A. cerana has been introduced to areas outside its natural range (namely New Guinea, the Solomon Islands, and Australia), which sparked fears that it may become a pest species that could compete with, and negatively affect, native Australian fauna and flora, as well as commercially kept A. mellifera and commercial crops. This literature review is a response to these concerns and reviews what is known about the ecology and behaviour of A. cerana. Differences between temperate and tropical strains of A. cerana are reviewed, as are A. cerana pollination, competition between A. cerana and A. mellifera, and the impact and control strategies of introduced A. cerana, with a particular focus on gaps of current knowledge.

Introduction Apis cerana Fabricius (also known as the Asian honeybee, Asiatic bee, Asian hive bee, Indian honeybee, Indian bee, Chinese bee, Mee bee, Eastern honeybee, and Fly Bee) is endemic to most of Asia where it has been used for honey production and pollination services for thousands of years. -
A Saliva Protein of Varroa Mites Contributes to the Toxicity Toward Apis Cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A
www.nature.com/scientificreports OPEN A Saliva Protein of Varroa Mites Contributes to the Toxicity toward Apis cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A. mellifera Published: xx xx xxxx Yi Zhang & Richou Han Varroa destructor mites express strong avoidance of the Apis cerana worker brood in the feld. The molecular mechanism for this phenomenon remains unknown. We identifed a Varroa toxic protein (VTP), which exhibited toxic activity toward A. cerana worker larvae, in the saliva of these mites, and expressed VTP in an Escherichia coli system. We further demonstrated that recombinant VTP killed A. cerana worker larvae and pupae in the absence of deformed-wing virus (DWV) but was not toxic to A. cerana worker adults and drones. The recombinant VTP was safe for A. mellifera individuals, but resulted in elevated DWV titers and the subsequent development of deformed-wing adults. RNAi- mediated suppression of vtp gene expression in the mites partially protected A. cerana larvae. We propose a modifed mechanism for Varroa mite avoidance of worker brood, due to mutual destruction stress, including the worker larvae blocking Varroa mite reproduction and Varroa mites killing worker larvae by the saliva toxin. The discovery of VTP should provide a better understanding of Varroa pathogenesis, facilitate host-parasite mechanism research and allow the development of efective methods to control these harmful mites. Varroa destructor Anderson & Trueman (Acari: Varroidae) was originally identifed as an ectoparasite of the Asian honeybee Apis cerana. Before the year 2000, V. destructor was miscalled V. jacobsoni. In fact, these two species are diferent in body shape, cytochrome oxidase (CO-I) gene sequence, and virulence to honey bees1. -

Population Growth of Varroa Destructor (Acari: Varroidae) in Commercial Honey Bee Colonies Treated with Beta Plant Acids
Exp Appl Acarol DOI 10.1007/s10493-014-9821-z Population growth of Varroa destructor (Acari: Varroidae) in commercial honey bee colonies treated with beta plant acids Gloria DeGrandi-Hoffman • Fabiana Ahumada • Robert Curry • Gene Probasco • Lloyd Schantz Received: 3 September 2013 / Accepted: 28 April 2014 Ó The Author(s) 2014. This article is published with open access at Springerlink.com Abstract Varroa (Varroa destuctor Anderson and Trueman) populations in honey bee (Apis mellifera L.) colonies might be kept at low levels by well-timed miticide applica- tions. HopGuardÒ (HG) that contains beta plant acids as the active ingredient was used to reduce mite populations. Schedules for applications of the miticide that could maintain low mite levels were tested in hives started from either package bees or splits of larger colonies. The schedules were developed based on defined parameters for efficacy of the miticide and predictions of varroa population growth generated from a mathematical model of honey bee colony–varroa population dynamics. Colonies started from package bees and treated with HG in the package only or with subsequent HG treatments in the summer had 1.2–2.1 mites per 100 bees in August. Untreated controls averaged significantly more mites than treated colonies (3.3 mites per 100 bees). By October, mite populations ranged from 6.3 to 15.0 mites per 100 bees with the lowest mite numbers in colonies treated with HG in August. HG applications in colonies started from splits in April reduced mite populations to 0.12 mites per 100 bees. In September, the treated colonies had significantly fewer mites than the untreated controls. -
Varroa Destructor, Varroa Mite Mesostigmata
Varroa destructor, Varroa mite (Mesostigmata: Varroidae) Christopher J. Fellows, Forest Huval, Chris Carlton and Gene Reagan internal fluids (haemolymph). The mites are visible to the naked eye. While they may sometimes be observed attached to adult honey bees within the colony, this is not an effective means of detection. Life Cycle Varroa mites reproduce on a 10-day cycle that is completely dependent on the life cycle of honey bees. A female mite, called the foundress, enters the honey bee brood cell just prior to capping and hides beneath the puddle of liquid food at the bottom of the brood cell. The foundress mite uses a pair of snorkel-like organs, called peritremes, to breathe while hiding Adult female Varroa destructor mites. Scott Bauer, beneath the brood food. Around five hours after the brood cell USDA Agricultural Research Service, Bugwood.org. is capped, the worker bee larvae will have eaten the remainder of this food, freeing the mite. The foundress mite may then begin feeding on the fat body and body fluid (hemolymph) of the developing bee. Around 70 hours after the brood cell is capped, the foundress lays her first egg, which is unfertilized and develops into a male mite. The foundress then lays three to four more eggs, all of which are fertilized and thus develop into females. After maturing, the virgin female mites will mate with their male brother within the cell of the still-developing worker bee. The male mite dies shortly after mating, and the foundress and newly mated female daughters exit the cell with the now- mature adult worker bee. -

Some honey bee populations are resistant to the mite, but most of the commercially used stocks are not and rely on chemical treatment. In this article, we describe known varroa-resistant populations and the mechanisms which have been identified as responsible for survival of colonies without beekeeper intervention to control the mite. We review traits that have potential in breeding programs, discuss the role played by V. destructor as a vector for virus infections, and the changes in mite and virus virulence which could play a role in colony resistance. -
Of the Red Honeybee Apis Koschevnikovi Von Buttel-Reepen, 1906 in Sabah, Borneo
Original article Expression of body and hair color in three adult castes of the red honeybee Apis koschevnikovi von Buttel-Reepen, 1906 in Sabah, Borneo J Woyke Bee Division, Agricultural University - SGGW, 166 Nowoursynowska, 02-787 Warsaw, Poland (Received 10 December 1996; accepted 15 July 1997) Summary — Apis koschevnikovi bees were collected in Sabah, Borneo. A total of 303 workers from ten colonies were measured in 1995, and 500 workers, 200 drones and ten queens were inves- tigated in 1996. Measurements were made of the width of the dark bands on terga II, III and IV. Drawings of the different body color patterns were made. The workers are light orange with dark brown bands on abdominal terga. Body color patterns were assigned to five groups. The successive groups are gradually darker. Queens and drones have different color patterns and are darker than the work- ers. The upper part of the head and the scutum are black, and the dark brown bands on terga are similar in all three bee castes. However, the light colored body parts such as clypeus, scutellum, and the light abdominal bands are light orange or orange in workers and light brown or reddish brown in the sexuals: queens and drones. The major gene responsible for body color in A koschevnikovi is proposed to be designated as Ko. Hairs covering the thoraces of workers, queens and drones are light orange, gold and gray, respectively. The gene responsible for the color of these hairs is proposed to be designated as Kh.

Controlling Varroa Mites in Honey Bee Colonies
Last updated 7/11/2019 Controlling Varroa Mites in Honey Bee Colonies Compiled by Jessica Sullivan, UF IFAS Extension, Osceola County, FL and J.R. Denman, UF Advanced Level Beekeeper, Osceola County, FL The varroa mite The varroa mite (Varroa destructor) is the most harmful pest that affects European honey bees. Native to Asia, it is now found throughout the U.S. It is an ectoparasite on pupal, larval and adult bees, feeding on bees. It weakens bees and also spreads destructive viruses in bee colonies. Monitoring for varroa mites Why monitor- Varroa mites are not easily visible in bee colonies. Therefore, it is necessary to monitor for varroa mites using at least one of the methods below so beekeepers can treat if mite populations become too high. Monitoring for varroa mites can give you an idea of how many mites are present in your colonies and help you decide whether treatment is needed. You may need a strong magnification hand lens to identify mites when using the following sampling methods. Adult female varroa mite on honey bee larva. Photos: J. Sullivan When to monitor-Monitoring for varroa mites may be done at any time and if using sticky boards, as often as you like. Varroa are present and may become problematic during any season in Florida. Suggested monitoring schedule for Osceola County, FL: February (jar method of sampling)- so you can treat if necessary before placing honey supers. June (sticky board) July- (sticky board) right after harvesting spring honey, so you can treat if necessary, before placing honey supers for the fall nectar flow. -

In drone brood, slightly higher JH III hemolymph con- centrations were recorded. These results do not agree with the hypothesis that reproduction of the parasitic bee mite Varroa jacobsoni is regulated by host-derived JH. After checking over a thousand capped brood cells containing pupae, it was confirmed that in Apis cerana colonies fertility of female mites is restricted to drone hosts.
