Africanized honeybees in urban areas: a public health concern [PDF]
Revista Da Sociedade Brasileira De Medicina Tropical, 2014 Introduction This study aimed to investigate the occurrence of Africanized honeybees in Botucatu, São Paulo, Brazil, and to implement a program to remove such swarms.

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).

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.

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.

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.

Living with the Africanized bee: Sinaloan beekeepers adapt pollination to Africanized bees
California Agriculture, 1996 Africanized honeybees have become well established in Sinaloa, Mexico, which has large-scale agriculture similar to California's. Beekeepers in Sinaloa have adapted their management practices to continue to provide pollination of crops.

Genomewide analysis of admixture and adaptation in the Africanized honeybee [PDF]
Molecular Ecology, 2017 AbstractGenetic exchange by hybridization or admixture can make an important contribution to evolution, and introgression of favourable alleles can facilitate adaptation to new environments. A small number of honeybees (Apis mellifera) with African ancestry were introduced to Brazil ~60 years ago, which dispersed and hybridized with existing managed ...

Africanized honeybee stings: how to treat them [PDF]
Revista da Sociedade Brasileira de Medicina Tropical, 2011 INTRODUCTION: In 1956, Africanized honeybees (AHB) migrated from Brazil to other regions of the Western Hemisphere, including South, Central, and North America, except for Canada. Despite being productive, they are highly aggressive and cause fatal accidents.

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 ...

Range and Frequency of Africanized Honey Bees in California (USA). [PDF]
PLoS ONE, 2015 Africanized honey bees entered California in 1994 but few accounts of their northward expansion or their frequency relative to European honey bees have been published. We used mitochondrial markers and morphometric analyses to determine the prevalence of
