Genetic parameters for five traits in Africanized honeybees using Bayesian inference [PDF]
Genetics and Molecular Biology, 2013 Heritability and genetic correlations for honey (HP) and propolis production (PP), hygienic behavior (HB), syrupcollection rate (SCR) and percentage of mites on adult bees (PMAB) of a population of Africanized honeybees were estimated.

Varroa destructor mite in Africanized honeybee colonies Apis mellifera L. under royal jelly or honey production [PDF]
Acta Scientiarum: Animal Sciences, 2015 This study evaluated the level of invasion of Varroa mite into worker brood cells, the infestation rate on adult worker honeybees, total and effective reproduction rates of the mite in Africanized honeybee colonies under royal jelly or honey production ...

Venom production by Africanized honeybees (Apis mellifera) and Africanized-European hybrids
Journal of Venomous Animals and Toxins, 2001 This study used 15 beehives: five with Africanized queens sisters (Apis mellifera), five with Italian queens sisters (Apis mellifera ligustica), and five with Carniolan queens sisters (Apis mellifera carnica). The queens were fertilized naturally. This experiment was performed in the apiary of the Botucatu School of Veterinary Medicine and Animal ...

Genetic structure of drone congregation areas of Africanized honeybees in southern Brazil [PDF]
Genetics and Molecular Biology, 2009 As yet, certain aspects of the Africanization process are not well understood, for example, the reproductive behavior of African and European honeybees and how the first Africanized swarms were formed and spread.

Morphometrics and adaptatives aspects in africanized honeybees (Apis mellifera) [PDF]
Revista Brasileira de Biologia, 2000 The introduction of the African bees (Apis mellifera scutelata) in Brazil and their expansion in the American Continent created the opportunity to study the process of species adaptation in a new environment. In that process, within intra-specific variability, normalising selection can favour individuals that present a better adaptative morphology and ...

Characterization of the Bacterial Communities Inhabiting Tropical Propolis of Puerto Rico [PDF]
Microorganisms, 2023 Propolis is a resinous material produced by honeybees from different plant sources and used in the hive as a building material and to protect the colony from parasites and pathogens.

Africanized honeybees are slower learners than their European counterparts. [PDF]
Naturwissenschaften, 2010 Does cognitive ability always correlate with a positive fitness consequence? Previous research in both vertebrates and invertebrates provides mixed results. Here, we compare the learning and memory abilities of Africanized honeybees (Apis mellifera scutellata hybrid) and European honeybees (Apis mellifera ligustica).

Environmental physiology of the invasion of the Americas by Africanized honeybees [PDF]
Integrative and Comparative Biology, 2006 The expansion of Africanized honeybees (AHB) through the Americas has been one of the most spectacular and best-studied invasions by a biotype. African and European honeybees (EHB) hybridize, but with time, tropical and subtropical American environments have become dominated by AHB that exhibit only 20-35% genetic contribution from western European ...

Scientia Agricola, 1997 Africanized honeybees from five colonies were marked with P-32 and taken to an apple grove for a flight behavior study. The method used to determine the flight range was to put out an array of tagged trees in a cross pattern with the colonies arranged in
