“…Ruijter, 1987 (Liebig, 1994;Boot et al, 1995;Mar-tin, unpublished data) that suggested a strong correlation between levels of falling mites and the emergence of honeybee brood. The level of mite drop from naturally infested worker cells was nearly twice as high as that from the drone cells, despite drone cells being more attractive to the mite (Fuchs, 1990 (Martin, 1994) (Nation et al, 1992). This may also explain why proportionally more live mites were found to fall from emerging worker than drone cells.…”

Summary — In a naturally infested colony a strong correlation between levels of falling mites and the emergence of honeybee brood was found. When comparing the number of mites falling between emerging worker and drone brood with known infestation levels, the mite fall was 2-3 times higher from worker than from drone cells. It was estimated that around half of the falling mites originate from mites that died within the sealed cell with the other half dying shortly after bee emergence. About 50% of the fallen mites were still alive and found to be able to reproduce when artificially introduced into sealed brood cells. The implications of mite mortality associated with brood emergence on the mite population dynamics and of using numbers of falling mites as a monitoring tool are discussed.

“…Therefore, an effect of mite scent cannot be completely excluded. However, this polar fraction could be the only source for mite specific cues as the unpolar cuticular hydrocarbon pattern of mites is known to be similar to those of pupae (Nation et al, 1992). In the case of unusual brood cell intruders, odour cues might be more important as indicated by our experiments with dead ants.…”

“…In principle, both mechanical and chemical stimuli could be the source of the releasers, potentially originating from both the brood and from the parasite (Masterman et al, 2000;Nation et al, 1992). In the original host of V. destructor (Anderson, 2000;Anderson and Trueman, 2000), the Asian hive bee Apis cerana Fabr., alien scent adhering to mites was found to elicit hygienic behaviour (Rosenkranz et al, 1993).…”

“…Morphological (Grobov et al 1980;Delfinado-Baker & Houck 1989), allozymic (Issa 1989;Biasiolo 1992) and cuticular hydrocarbon (Nation et al 1992) analyses have evidenced some differences mainly between the two types, but very few, if any, within each type.…”

Varroa destructor , now a major pest of the Western honeybee, Apis mellifera , switched from its original host, the Eastern honeybee, A. cerana , ca . 50 years ago. So far, only two out of several known mitochondrial haplotypes of V. destructor have been found to be capable of reproducing on A. mellifera (Korea and Japan). These haplotypes are associated in almost complete cytonuclear disequilibrium to diagnostic alleles at 11 microsatellite loci. By contrast, microsatellite polymorphism within each type is virtually absent, because of a severe bottleneck at the time of host change. Accordingly, 12 mitochondrial sequences of 5185 nucleotides displayed 0.40% of nucleotide divergence between haplotypes and no intra haplotype variation. Hence, each type has a quasi–clonal structure. The nascent intratype variability is subsequent to the clone formation 50 years ago: in both types the variant alleles differ from the most common by one (in 10 cases), two (five cases) or three (one case) repeated motifs. In addition to individuals of the two ‘pure’ types, five F 1 hybrids and 19 recombinant individuals (Japan alleles introgressed into the Korea genetic background) were detected. The existence of F 1 and recombinant individuals in admixed populations requires that double infestations of honeybee cells occur in a high proportion but the persistence of pure types suggests a post–zygotic isolation between the two clones.
