A.  aVarroa destructor in Africanized honey bees in Brazilbgenetic and reproductive profile.h[electronic resource]  c2022  aThe mite Varroa destructor is one of the most studied parasites in apiculture, and its genotype variation is a key factor for the severity of infestation in bee colonies. Here we report the genetic and reproductive profile of mites from 14 Brazilian states with different geographic and climatic conditions. We performed PCR to amplify a fragment of the COI gene and differentiate the haplotypes using restriction enzymes. The K haplotype was widely prevalent in the studied sites, while the J haplotype was found only in four municipalities. We also observed both haplotypes (J and K) coexisting in the same colony, a fact unprecedented in Brazil. Infestation levels were low (0.33 to 15.3%). The reproductive potential showed wide variation (0 to 1.5), indicating that even with the massive presence of K haplotype, environmental and biotic factors related to Africanized honeybees may be responsible for maintaining the mite under low levels in Brazil.  aAcari  aApidae  aAbelha Africana  aParasita  aPatologia  aPerfil genético  aPerfil reprodutivo1 aTEIXEIRA, E.
