“…Despite an increase in mite fertility or the presence of the Korean mite haplotype, the Africanized honeybee population remains stable in Brazil and there have been no reports of increased mite infestation rates (Carneiro et al 2007;Garrido et al 2003;Vandame and Palacio 2010). This suggests that mite resistance in this population is (a) based on host factors rather than parasitic virulence and (b) probably owing to a combination of traits additively reducing the mite population growth rather than a single trait alone, such as reduced mite fertility.…”

“…Carneiro et al 2007 reported an increase of mite fertility in Brazil from 56 % in the 1980s to 86 % in [2005][2006]. Mite haplotype virulence could also explain the higher mite fertility rates found in Africanized honeybees in Mexico since only the Korean haplotype has been found there (Medina and Martin 1999;Mondragon et al 2005;.…”

Natural Varroa mite-surviving Apis mellifera honeybee populations

-The Varroa destructor mite is the largest threat to apiculture worldwide and has been responsible for devastating losses of wild honeybee populations in Europe and North America. However, Varroa mite-resistant populations of A. mellifera honeybees have been reported and documented around the world with a variety of explanations for their long-term survival with uncontrolled mite infestation. This review synthesizes the work on naturally occurring survival to Varroa mites and discusses what these honeybee populations can signify for apiculture.Varroa destructor / mite resistance / host-parasite adaptations / natural selection / apiculture

“…However, fertility rates can change over time, as was found in Brazilian honeybees where mite fertility was low before the late 1990's but increased after this period (Corrêa-Marques et al 2003;Garrido et al 2003;Carneiro et al 2007). Even though most of the evidence obtained so far points towards Varroa mite tolerance in both sub-species of South Africa, Martin and Kryger (2002) found that Varroa mite reproductive rates were similar in A. m. scutellata and European honeybees, thereby suggesting that Varroa mites should have the same negative effect in A. m. scutellata as in European honeybees.…”

“…A significant amount of research has been done on the genetic and behavioural composition of the invasive Africanised honeybee, with most of the research indicating that a high percentage of African characters are conserved within these populations (Schneider et al 2004;Moritz et al 2005;Whitfield et al 2006;Kraus et al 2007). In Brazil, Varroa mite infestation rates of Africanised honeybee colonies have remained very low over the years, from when the mite was first observed in the late seventies up until recent times (Rosenkranz 1999), with no reports of large scale honeybee mortality (De Jong et al 1984;Camazine and Morse 1988;Carneiro et al 2007;Calderón et al 2010). In general, tolerance to Varroa mites in Africanised honeybees has been attributed to the presence of a large number of infertile female mites (Camazine 1986;Rosenkranz and Engels 1994), the uncapping and removal of mite infested brood (Corrêa-Marques and De Jong 1998;Guerra et al 2000;Vandame et al 2002) and the mortality of both male and female mite offspring, which decreases the reproductive output of the mites (Medina and Martin 1999;Mondragón et al 2005;Mondragón et al 2006).…”

Impact of Varroa destructor on honeybee (Apis mellifera scutellata) colony development in South Africa

The devastating effects of Varroa destructor on European honeybee colonies (Apis mellifera L.) have been well documented. Not only do these mites cause physical damage to parasitised individuals when they feed on them, they also transmit viruses and other pathogens, weaken colonies and can ultimately cause their death.Nevertheless, not all honeybee colonies are doomed once Varroa mites become established. Some populations, such as the savannah honeybee, A. m. scutellata, have become tolerant after the introduction of the parasite and are able to withstand the presence of these mites without the need for acaricides. In this study, we measured daily Varroa mite fall, Varroa infestation rates of adult honeybees and worker brood and total Varroa population size in acaricide treated and untreated honeybee colonies. In addition, honeybee colony development was compared in order to measure the cost incurred by Varroa mites to their hosts. Daily Varroa mite fall decreased over the experimental period with different dynamics in treated and untreated colonies. Varroa infestation rates in treated adult honeybees and brood were lower than in untreated colonies, but not significantly so. Thus indicating a minimal benefit of treatment thereby suggesting that A. m. scutellata have the ability to maintain mite populations at low levels. We obtained baseline data on Varroa population dynamics in a tolerant honeybee over the winter period. Varroa mites appeared to have a low impact on this honeybee population, given that colony development was similar in the treated and untreated colonies.

“…17 Since worker brood rearing and thus Varroa reproduction occurs all year round in 18 tropical climates, it could be expected that the impact of the parasite would be even 19 worse in tropical regions. But Varroa destructor has been present in Brazil for more 20 than 30 years and yet no collapses due to this mite, have been recorded [3]. It is worth 21 noting that the dominant variety of bees in Brazil is the Africanized honey bee (AHB) 22 which since its introduction in 1956, has spread to the entire country [4].…”

Colony Collapse Disorder has become a global problem for beekeepers and for the crops which depend on bee polination. Multiple factors are known to increase the risk of colony colapse, and the ectoparasitic mite Varroa destructor that parasitizes honey bees (Apis melifera) is among the main threats to colony health. Although this mite is unlikely to, by itself, cause the collapse of hives, it plays an important role as it is a vector for many viral AbstractColony Collapse Disorder has become a global problem for beekeepers and for the crops which depend on bee polination. Multiple factors are known to increase the risk of colony colapse, and the ectoparasitic mite Varroa destructor that parasitizes honey bees is among the main threats to colony health. Although this mite is unlikely to, by itself, cause the collapse of hives, it plays an important role as it is a vector for many viral diseases. Such diseases are among the likely causes for Colony Collapse Disorder.The effects of V. destructor infestation are disparate in different parts of the world. Greater morbidity -in the form of colony losses -has been reported in colonies of European honey bees (EHB) in Europe, Asia and North America. However, this mite has been present in Brasil for many years and yet there are no reports of Africanized honey bee (AHB) colonies losses.Studies carried out in Mexico showed that some resistance behaviors to the miteespecially grooming and hygienic behavior -appear to be different in each subspecies. Could those difference in behaviors explain why the AHB are less susceptible to Colony Collapse Disorder?In order to answer this question, we propose a mathematical model of the coexistence dynamics of these two species, the bee and the mite, to analyze the role of resistance behaviors in the overall health of the colony, and, as a consequence, its ability to face epidemiological challenges.
