“…The degree of mite tolerance in Mexico seems to be lower compared to that of AHBs in Brazil (Guzmán-Novoa et al, 1999), but the system is also stable . However, the fertility of mites has been found to be slightly higher than in Brazil (88% Medina and Martin, 1999;83-96% Medina et al, 2002;82-97% Vandame et al, 1999).…”

-The relationship between fertility and haplotype was studied in Varroa destructor mites sampled from colonies of A. mellifera carnica and Africanized Honeybees (Apis mellifera) in Germany and Brazil respectively. Both in Germany and in Brazil, only the V. destructor Korea haplotype was found, though the Japan-Thailand haplotype was formerly thought to have been more abundant in Brazil. The fertility of Varroa mites in Brazil has increased since 1998 and is currently (2001) at European levels. Temporal changes in mite fertility and haplotype are not fully congruent.Varroa destructor / Apis mellifera / host-parasite relationship / reproduction / COI gene / RFLP

“…Observations in the original host, Apis cerana, suggest that its tolerance to Varroa is in part due to mechanisms of behavioral defense like grooming and removal of infested brood (Rosenkranz et al, 1993;Boecking and Spivak, 1999;Rath, 1999). Similar reactions have also been assumed for Africanized honey bees, reactions which have been considered less well expressed in non-Varroa-tolerant European honey bees (Guzman-Novoa et al, 1999;Guerra et al, 2000).…”

“…Comparative data on hygienic behavior in honey bees of different strain or origin are rare (Boecking and Ritter, 1993;Moretto et al, 1993;Guzman-Novoa et al, 1999;Guerra et al, 2000). Our study represents one of the first long-term surveys of tolerant and susceptible colonies which were kept side by side.…”

“…The Africanized honey bee of Brazil (De Jong et al, 1984;Moretto et al, 1991;Rosenkranz, 1999) is one of the few examples of long-term tolerance to varroosis in Apis mellifera (Boecking and Ritter, 1993;Guzman-Novoa et al, 1999;Rosenkranz, 1999). Although no treatment is carried out by Brazilian beekeepers, neither colony losses nor economic impact are recorded.…”

“…The testing of varroosis tolerant and susceptible honey bee strains should be done during the brood season in side-by-side experiments, using strong and normally breeding colonies. Because so far only a few experiments under such well-defined comparative conditions have been carried out with Africanized honey bees (Corrêa-Marques and De Jong, 1998;Guzman-Novoa et al, 1999), we studied the hygienic response of colonies at a site in tropical Brazil across three summer seasons, using local Africanized honey bees and non-tolerant Carniolan colonies. …”

A comparison of the hygienic response of Africanized and European (Apis mellifera carnica) honey bees to Varroa-infested brood in tropical Brazil

In order to examine the significance of hygienic behavior for the tolerance to varroosis of Africanized honey bees, they were compared with non-tolerant Carniolans in tropical Brazil. Capped worker brood cells were artificially infested with living Varroa mites, and inspected some days later. Uncapping, disappearance of the introduced mite and removal of the pupa were recorded in a total of manipulated 3,096 cells during three summer seasons. The hygienic response varied between Africanized and Carniolan colonies, but this difference was significant only in one year, during which Africanized honey bees removed a significantly greater proportion of Varroa mites than European honey bees. A high proportion of the mites disappeared from artificially infested brood cells without damage to the pupae. The opening of the cell and the removal of the bee brood are independent traits of a graded response by adult workers towards mite-infested brood cells. We found a higher between-colony variation in the reaction towards Varroa-infested brood of Africanized honey bees compared to Carniolans. The overall similar response of the two bee types indicates that hygienic behavior is not a key factor in the tolerance to varroosis of Africanized bees in Brazil.
Com o intuito de examinar o significado do comportamento higiênico na tolerância à varroose de abelhas africanizadas, elas foram comparadas com as não tolerantes Cárnicas no Brasil tropical. Células de cria de operárias operculadas foram artificialmente infestadas com ácaros Varroa vivos e inspecionadas alguns dias depois. Desoperculação, desaparecimento dos ácaros introduzidos e remoção da pupa foram anotados em um total de 3096 células manipuladas durante três verões. A resposta higiênica variou entre as colônias africanizadas e de Cárnicas, mas esta diferença foi significante apenas em um ano, durante o qual as abelhas africanizadas removeram uma proporção significantemente maior de ácaros Varroa que as abelhas européias. Uma grande porporção de ácaros desapareceram das células das crias artificialmente infestadas, sem danos às pupas. A abertura da célula e remoção das crias das abelhas são características independentes de uma resposta graduada por parte de operárias adultas com relação a células de crias infestadas por ácaros. Nós encontramos uma variação maior entre colônias na reação de abelhas africanizadas à cria infestada por Varroa, quando comparadas a abelhas Cárnicas. A resposta geralmente similar dos dois tipos de abelhas indica que o comportamento higiênico não é um fator importante na tolerância à varroose de abelhas africanizadas no Brasil

Reproduction of parasitic mites Varroa destructor in original and new honeybee hosts

The ectoparasitic mite, Varroa destructor, shifted host from the eastern honeybee, Apis cerana, to the western honeybee, Apis mellifera. Whereas the original host survives infestations by this parasite, they are lethal to colonies of its new host. Here, we investigated a population of A. cerana naturally infested by the V. destructor Korea haplotype that gave rise to the globally invasive mite lineage. Our aim was to better characterize traits that allow for the survival of the original host to infestations by this particular mite haplotype. A known major trait of resistance is the lack of mite reproduction on worker brood in A. cerana. We show that this trait is neither due to a lack of host attractiveness nor of reproduction initiation by the parasite. However, successful mite reproduction was prevented by abnormal host development. Adult A. cerana workers recognized this state and removed hosts and parasites, which greatly affected the fitness of the parasite. These results confirm and complete previous observations of brood susceptibility to infestation in other honeybee host populations, provide new insights into the coevolution between hosts and parasites in this system, and may contribute to mitigating the large‐scale colony losses of A. mellifera due to V. destructor.
