“…Second, as previously mentioned, the sheer numbers of Africanized drones and their predisposition for parasitizing colonies (Rinderer et al 1985) could account for a shift toward an Africanized nuclear genome in managed European colonies. Any positive assortative mating tendencies (Kerr and Bueno 1970) of Africanized bees would further enhance the Africanization process.…”

Abstract. Until recently, African and European subspecies of the honeybee (Apis mellifera L.) had been geographically separated for around 10,000 years. However, human-assisted introductions have caused the mixing of large populations of African and European subspecies in South and Central America, permitting an unprecedented opportunity to study a large-scale hybridization event using molecular analyses. We obtained reference populations from Europe, Africa, and South America and used these to provide baseline information for a microsatellite and mitochondrial analysis of the process of Africanization of the bees of the Yucatan Peninsula, Mexico. The genetic structure of the Yucatecan population has changed dramatically over time. The pre-Africanized Yucatecan population (1985) comprised bees that were most similar to samples from southeastern Europe and northern and western Europe. Three years after the arrival of Africanized bees (1989), substantial paternal gene flow had occurred from feral Africanized drones into the resident European population, but maternal gene flow from the invading Africanized population into the local population was negligible. However by 1998, there was a radical shift with both African nuclear alleles (65%) and Africanderived mitochondria (61%) dominating the genomes of domestic colonies. We suggest that although European mitochondria may eventually be driven to extinction in the feral population, stable introgression of European nuclear alleles has occurred.

“…The above differences between cruising altitudes of A. m. ligustica and A. m. carnica drones were discussed as a mechanism of assortative mating (i.e., incomplete reproductive isolation) [29]. Assortative mating has been reported to occur in a mixed population of A. m. ligustica and A. m. scutellata in South America [25].…”

“…The Africanized bees of Brazil, which originated from crosses of African bees (Apis mellifera scutellata) with European bees (Italian, Apis mellifera ligustica, and German, Apis mellifera mellifera), have been studied in terms of the most diverse aspects such as defensive behavior (Stort, 1971), flight activity (Kerr et al, 1970), communication (Gonçalves, 1969), mating competition (Martinho, 1979), hygienic behavior (Message, 1979), foraging behavior (Beig et al, 1972;Malaspina & Stort, 1987;Neves-Fermiano & Stort, 1985) and also in terms of outer morphology (Gonçalves, 1970;Daly & Balling, 1978;Cosenza & Batista, 1972;Stort, 1979;Stort & Bueno, 1985). Informations has also been obtained about this new type of bee in terms of the antennae, which are organs rich in sensory structures (Stort & Barelli, 1981;Stort, 1979;Moraes, 1988;Rebustini, 1995;Stort & Rebustini, 1998).…”

The number of sensilla campaniformia and sensilla coeloconica + sensilla ampullacea of flagellomeres 2 to 11 of the antennae of three types of males (Italian, African and Africanized) was determined by scanning electron microscopy. Comparison of the three male types showed that Italian males did not differ from African males in number of sensilla coeloconica + sensilla ampullacea and that both differed from Africanized males in terms of flagellomere 11. With respect to flagellomeres 3 and 10, Italian males were similar to Africanized males and both differed from African males. No differences between the three male types were detected in the other flagellomeres. In relation to the number of sensilla campaniformia Italian males differed of the African and Africanized males with respect to flagellomere 11.Key words: antennae, flagellomeres, sensilla, Apis mellifera. RESUMO Diferenças no número de estruturas sensoriais antenares de machos de 3 tipos de abelhas melíferasO número de sensilla campaniformia e sensilla coeloconica + sensilla ampullacea dos flagelômeros 2 ao 11 das antenas de 3 tipos de machos (italianos, africanos e africanizados) foi estudado através do microscópio eletrônico de varredura. As comparações dos 3 tipos de machos mostraram que, em relação ao número de sensilla coeloconica + ampullacea, os italianos não diferiram dos africanos e ambos eram diferentes dos africanizados em termos do flagelômero 11. Em relação aos flagelômeros 3 e 10, os italianos eram semelhantes aos africanizados e ambos diferiram dos africanos. Nos outros flagelômeros não foram verificadas diferenças entre os três tipos de machos. Em relação ao número de sensilla campaniformia, os italianos diferiram dos africanos e dos africanizados quanto ao flagelômero 11.Palavras-chave: antenas, flagelômeros, sensilla, Apis mellifera.
