Different Levels

Different levels of infestation with the mite Varroa jacobsoni have been observed in the various Apis mellifera races. In general, bees of European races are more susceptible to the mite than African honey bees and their hybrids. In Brazil honey bee colonies are not treated against the mite, though apparently both climate and bee race influence the mite infestation. Six mixed colonies were made with Italian and Africanized honey bees. The percentage infestation by this parasite was found to be significantly lower in adult Africanized (1.69 ± 0.44) than Italian bees (2.79 ± 0.65). This ratio was similar to that found in Mexico, even though the Africanized bees tested there had not been in contact with varroa, compared to more than 20 years of the coexistence in Brazil. However, mean mite infestation in Brazil on both kinds of bees was only about a third of that found in Mexico.

Host Parasite

We investigated the relationships between the honey bee, Apis mellifera, and the parasitic mite Varroa jacobsoni in Mexico. In an 18-month survey of European honey bees (EHB) and Africanized honey bees (AHB), we showed that EHB were highly compatible with V. jacobsoni, while AHB were not as compatible. Furthermore, mite infertility ("parasite infectivity" factor), suspected to be the main factor of low AHB/V. jacobsoni compatibility in Brazil, was not observed in Mexico. The "intrinsic rate of natural increase" of mites did not differ significantly between host subspecies, indicating that the cause of low compatibility appears only at high parasite densities. The "carrying capacity" was twice as high in EHB as in AHB, indicating that the cause of low compatibility is possibly linked to honey bees' behavior. We hypothesize that the reason why V. jacobsoni is highly fertile on Mexican AHB (whereas it has low fertility on Brazilian AHB) may be that different strains of V. jacobsoni exist in the two countries.
