Prevalence of African DNA RELP alleles in neotropical African honeybees

Archives of Insect Biochemistry and Physiology, 1990
AbstractA few queens of the honeybee, Apis mellifera scutellata, were imported from Africa and released in Brazil in 1957. Progeny of these bees have now largely colonized the American tropics. Their imminent arrival in the United States poses a serious threat to the beekeeping industry and to agriculture dependent on honeybee pollination.

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.

Electrophoretic Identification of Africanized Honeybees

Journal of Apicultural Research, 1982
SummaryA procedure for analysing the results of protein electrophoresis for taxonomic purposes is described. Its application to identifying Africanized honeybees is presented, using previously reported data for the loci coding for malate dehydrogenase (Mdh), alcohol dehydrogenase (Adh), and a general protein band (P-3).

Biochemical response of the Africanized honeybee exposed to fipronil

Environmental Toxicology and Chemistry, 2016
Abstract   Bees are recognized worldwide for their social, economic, and environmental value. In recent decades they have been seriously threatened by diseases and high levels of pesticide use.

Multiple African Honeybee Stings and Acute Renal Failure

Nephron, 1998
In 1956, the Brazilian government brought honeybees <i>(Apis mellifera andansonii)</i> from South Africa. A group of these bees crossed the Amazon and reached Venezuela where they have killed between 30 and 50 people in the last 4 years [1].

Identification of Africanized honeybees via nonlinear multilayer perceptrons

Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94), 2002
Africanized ("killer") honeybees represent an immediate and serious threat to public and agricultural well-being in the southern United States due to their recent immigration from Central and South America. Discrimination of hybrid Africanized bees from native European-stock bees is problematic, and the current linear statistical tools used for this ...

Fertile diploid drones in africanized honeybees, Apis mellifera adansonii

Experientia, 1977
59 diploid drones of Apis mellifera adansonii, 12-37 days old, were tested for the presence of semen after provoked ejaculation; 13 drones ejaculated semen enough to be used in an instrumental insemination, but only three on them (5%) furnished 1 mm3 of semen.

Biochemical and immunochemical comparison of Africanized and European honeybee venoms

Journal of Allergy and Clinical Immunology, 1990
Africanized honeybees (HBs) pose a hazard to both normal and sting-sensitive subjects in certain areas of Central and South America, and it is predicted that they will soon be present in the southern United States as well. Using an electrical stimulation device, we collected Africanized HB venom (AHV) in Venezuela and European HB venom (EHV) in ...
