“…Losses of Africanized honey bee colonies due to varroosis are not reported and possible negative effects on honey production seem to be negligible [160]. This is surprising, as in contrast to South Africa, viruses associated with Varroa like Deformed Wing Virus are widespread in South America [164][165][166] and Africanized bees are not resistant against the virus [167,168], although in one study, the rate of virus increase was lower in Africanized bees than in European bees [169].…”

We examine evidence for natural selection resulting in Apis mellifera becoming tolerant or resistant to Varroa mites in different bee populations. We discuss traits implicated in Varroa resistance and how they can be measured. We show that some of the measurements used are ambiguous, as they measure a combination of traits. In addition to behavioural traits, such as removal of infested pupae, grooming to remove mites from bees or larval odours, small colony size, frequent swarming, and smaller brood cell size may also help to reduce reproductive rates of Varroa. Finally, bees may be tolerant of high Varroa infections when they are resistant or tolerant to viruses implicated in colony collapse. We provide evidence that honeybees are an extremely outbreeding species. Mating structure is important for how natural selection operates. Evidence for successful natural selection of resistance traits against Varroa comes from South Africa and from Africanized honeybees in South America. Initially, Varroa was present in high densities and killed about 30% of the colonies, but soon after its spread, numbers per hive decreased and colonies survived without treatment. This shows that natural selection can result in resistance in large panmictic populations when a large proportion of the population survives the initial Varroa invasion. Natural selection in Europe and North America has not resulted in large-scale resistance. Upon arrival of Varroa, the frequency of traits to counter mites and associated viruses in European honey bees was low. This forced beekeepers to protect bees by chemical treatment, hampering natural selection. In a Swedish experiment on natural selection in an isolated mating population, only 7% of the colonies survived, resulting in strong inbreeding. Other experiments with untreated, surviving colonies failed because outbreeding counteracted the effects of selection. If loss of genetic variation is prevented, colony level selection in closed mating populations can proceed more easily, as natural selection is not counteracted by the dispersal of resistance genes. In large panmictic populations, selective breeding can be used to increase the level of resistance to a threshold level at which natural selection can be expected to take over.

“…With the exception of Apis mellifera filamentous virus (AmFV) and Apis iridescent virus (AIV), which are DNA viruses, the vast majority of bee viruses have an RNA genome, surrounded by an icosahedral capsid 20-30 nm in size. Taxonomically, almost all of them are members of the order Picornavirales [37]. Among the viruses present in Argentina, DWV and sacbrood bee virus (SBV) belong to the family Iflaviridae, and their virions contain a linear, positive-sense, singlestranded RNA molecule with a single large open reading frame (ORF) [77].…”

Viruses that affect Argentinian honey bees (Apis mellifera)

Beekeeping is a widespread activity in Argentina, mainly producing honey that has gained both national and international recognition. There are more than 3,000,000 hives in the country, mainly concentrated in Buenos Aires Province (approximately 1,000,000 hives). In recent decades, worrying rates of hive loss have been observed in many countries around the world. In Latin America, the estimated loss of hives is between 13% (Peru and Ecuador) and 53% (Chile). Argentina had annual losses of 34% for the period of October 1, 2016 to October 1, 2017. The causes of these losses are not clear but probably involve multiple stressors that can act simultaneously. One of the main causes of loss of bee colonies worldwide is infestation by the ectoparasitic mite Varroa destructor in combination with viral infections. To date, 10 viruses have been detected that affect honey bees (Apis mellifera) in Argentina. Of these, deformed wing virus, sacbrood virus, acute bee paralysis virus, chronic bee paralysis virus, and Israeli acute bee paralysis can be transmitted by mites. Deformed wing virus and the AIK complex are the viruses most often associated with loss of hives worldwide. Considering that bee viruses have been detected in Argentina in several hymenopteran and non-hymenopteran insects, these hosts could act as important natural reservoirs for viruses and play an important role in their dispersal in the environment. Further studies to investigate the different mechanisms by which viruses spread in the environment will enable us to develop various strategies for the control of infected colonies and the spread of viruses in the habitat where they are found.

“…Viruses spread in honeybees by two ways: vertical and horizontal transmission (de Miranda et al, 2012; Chagas et al, 2019;Beaurepaire et al, 2020). In vertical transmission route, viruses could spread from the infected queen by trans-ovarial transmission, through drones by trans-spermal transmission, or during their mating -known as venereal transmission to the off spring.…”

“…In vertical transmission route, viruses could spread from the infected queen by trans-ovarial transmission, through drones by trans-spermal transmission, or during their mating -known as venereal transmission to the off spring. In horizontal transmission route, the viruses spread amongst colony members of same age generation and between same and diff erent hives or apiaries via oral or contact route (de Miranda et al, 2012, Chagas et al, 2019;Ullah et al, 2021). In addition to this direct transmission routes, some viruses, like DWV, mainly spread among honeybees via Varroa destructor mites that become infected from infected bees and behave as a carrier to spread viruses to healthy bees when they feed on them (vector-borne transmission) that represents an example of indirect transmission (Ullah et al, 2021).…”

The honey bee Apis mellifera is an important beneficial insect recognized by production of honeybee products, having an important role in agricultural production through pollination, and play an equally crucial role in conserving the biodiversity in many natural ecosystems. According to available literature data, in the last more than 20 years, dramatic honey bee winter colony losses have been reported frequently all over the world that could have a direct influence on human food resources and can affect not only apiculture or agriculture, but also has an anthropological threats. One among many reasons for global bees-decline phenomenon is the influence of many viruses on honeybees’ health. Until today, in total, 36 viruses is detected in honey bees, and for many of them still without known pathogenicity on honeybees’ health. However, it is well known that some of these viruses like Acute Bee Paralysis Virus (ABPV), Chronic Bee Paralysis Virus (CBPV), Deformed Wing Virus (DWV), Black Queen Cell Virus (BQCV), Sacbrood Virus (SBV), Kashmir Bee Virus (KBV), Israeli Acute Paralysis Virus (IAPV), Slow bee paralysis virus (SBPV), Varroa destructor virus (VDV1) and some others has direct or indirect influence on individual honeybee or on whole honeybees colony health. In this paper the review of existing literature data on the presence, prevalence and characterization of honeybee viruses detected in honeybee colonies and apiaries from different regions in Serbia from first detection of their presence in 1986 till nowadays is presented and discussed.
