Heritability of sting characters in Africanized honeybees
In this paper we proposed to estimate the heritability of seven morphological characters that compose the sting apparatus ofthe Africanized honeybee workers. An experimental design to estimate genetic parameters was based ...
Induction of the split sting trait in Africanized Apis mellifera (Hymenoptera : Apidae) by cold treatment of pupae
(Amer Entomol Soc, 1999-07-01)
Split sting is the name given to a nonfunctional honey bee sting characterized by lancets not attached to the stylet. It has appeared in a mutant line in Brazil, and has provoked interest as a possible means to reduce honey ...
HISTORICAL PERSPECTIVE and HUMAN CONSEQUENCES of AFRICANIZED BEE STINGS IN THE AMERICAS
(Taylor & Francis Inc, 2012-01-01)
In 1956, Africanized bees began to spread in the American continent from southern Brazil, where original African bees mated with European bees. A few years later, in 1990, these Africanized bees reached the United States ...

A clinical trial protocol to treat massive Africanized honeybee (Apis mellifera) attack with a new apilic antivenom
Background: Envenomation caused by multiple stings from Africanized honeybees Apis mellifera constitutes a public health problem in the Americas. In 2015, the Brazilian Ministry of Health reported 13,597 accidents (incidence ...
Structural characterization of novel chemotactic and mastoparan peptides from the venom of the social wasp Agelaia pallipes pallipes by high-performance liquid chromatography/electrospray ionization tandem mass spectrometry
High-performance liquid chromatography/electrospray ionization mass spectrometry (HPLC/ESI-MS) and high-performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS) techniques were ...
Relationship among Apis mellifera L. stings, swarming and climate conditions in the city of Rio Claro, SP, Brazil
(Universidade Estadual Paulista (UNESP), Centro de Estudos de Venenos e Animais Peçonhentos (CEVAP), 2010-01-01)
The presence of bees (Apis mellifera L.) in urban areas has increased in recent years due to environmental disturbances caused by humans. Bee migration to cities may provoke serious accidents, since some people present ...
Tropical dermatology: Venomous arthropods and human skin Part I. Insecta
Although many tropical insects carry infectious diseases, cutaneous injury can occur by other mechanisms, for example erucism (envenomation by caterpillars) or lepidopterism (dermatitis from moths). Pararama is a unique ...

Production of the First Effective Hyperimmune Equine Serum Antivenom against Africanized Bees
(Public Library Science, 2013-11-13)
Victims of massive bee attacks become extremely ill, presenting symptoms ranging from dizziness and headache to acute renal failure and multiple organ failure that can lead to death. Previous attempts to develop specific ...
