Development Periods for Eggs of Africanized and European Honeybees

Journal of Apicultural Research, 1981
SummaryIn a side-by-side test in Venezuela, 593 eggs from 7 Africanized queen honeybees and 355 eggs from 7 European queens (from USA) were kept in an incubator (35 ± 1°C) without adult bees. Eggs from the two groups hatched after 69·6 ± 1·06 h and 73·3 ± 1·14 h, respectively (x ± SD), indicating a basic physiological difference between development ...

Heritability of morphological characters used to distinguish European and Africanized honeybees

Theoretical and Applied Genetics, 1991
Identification of "Africanized" honeybees (Apis mellifera) is usually achieved by measuring an array of morphological characters. Discriminant functions exist that allow determination of subspecies similarity on the basis of these measurements. Here we compute the heritabilities of the standard character set for ten eco-types (Table 1) of bees ...

Identification of Africanized honeybees

Journal of Chromatography A, 2005
Gas chromatography and pattern recognition methods were used to develop a potential method for differentiating European honeybees from Africanized honeybees. The test data consisted of 237 gas chromatograms of hydrocarbon extracts obtained from the wax glands, cuticle, and exocrine glands of European and Africanized honeybees.

Proteome and phosphoproteome of Africanized and European honeybee venoms

PROTEOMICS, 2013
Honey bee venom toxins trigger immunological, physiological, and neurological responses within victims. The high occurrence of bee attacks involving potentially fatal toxic and allergic reactions in humans and the prospect of developing novel pharmaceuticals make honey bee venom an attractive target for proteomic studies.

Engorgement and Dispersal of Africanized Honeybee Swarms

Journal of Apicultural Research, 1981
SummaryThe contribution of pre-swarming engorgement by workers to the energetics of long-distance dispersal by swarms of Africanized honeybees was examined, by measuring the volumes and concentrations of nectar from honey sacs of bees from different types of swarms.

An improved test for Africanized honeybee mitochondrial DNA

Experientia, 1991
Mitochondrial DNA derived from Apis mellifera scutellata, the ancestor of the Africanized bees of the New World, lacks a BglII restriction site found in other types of honeybee. We present primers allowing amplification of a 485-bp section of the cytochrome b gene containing this site, using the polymerase chain reaction.
