Resumo(s)
Polymerase chain reaction (PCR)-ampliÞed mitochondrialDNA(mtDNA)assays have
been used in studies of the Africanization process in neotropical feral and managed honey bee
populations. The approach has been adopted, in conjunction with morphometric analysis, to identify
Africanized bees for regulatory purposes in the United States such as in California. In this study, 211
Old World colonies, representing all known introduced subspecies in the United States, and 451
colonies from non-Africanized areas of the southern United States were screened to validate a rapid
PCR-based assay for identiÞcation of Africanized honey bee mtDNA. This PCR-based assay requires
a single enzyme digestion (BglII) of a single PCR-ampliÞed segment of the cytochrome b gene. The
BglII polymorphism discriminates the mitochondrial haplotype (mitotype) of Apis mellifera scutellata
L. (ancestor of Africanized bees) from that of A. m. mellifera, A. m. caucasia, A. m. ligustica, A. m.
carnica, A. m. lamarcki, A. m. cypria, A. m. syriaca, and some A. m. iberiensis, but not from that of
A. m. intermissa and some A. m. iberiensis. Nonetheless, given the very low frequency ( 1%) of African
non-A. m. scutellata mitotype present before arrival of Africanized bees in the United States, cytochrome
b/BglII assay can be used to identify maternally Africanized bees with a high degree of
reliability.
