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 ...

A
Molecular Ecology Resources, 2015 AbstractThe honeybee, Apis mellifera, is the world's most important pollinator and is ubiquitous in most agricultural ecosystems. Four major evolutionary lineages and at least 24 subspecies are recognized. Commercial populations are mainly derived from subspecies originating in Europe (75–95%). The Africanized honeybee is a New World hybrid of A.

Evaluation of the defensive behavior of two honeybee ecotypes using a laboratory test
Genetics and Molecular Biology, 2002 Honeybee defensive behavior is a useful selection criterion, especially in areas with Africanized honeybees (Apis mellifera L). In all genetic improvement programs the selected characters must be measured with precision, and because of this we evaluated ...

The Honeybee Disease American Foulbrood — An African Perspective [PDF]
African Entomology, 2011 Sustaining apiculture worldwide has been threatened by bee diseases and unexplained colony losses. African honeybee populations seem healthier and no major losses have been reported despite the presence of all the major pests and diseases. The scattered colonies in the large wild population of the continent might ensure slow pathogen spread and thus ...
