Heritability of sting characters in Africanized honeybees
(1997-01-01)
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 ...
Africanized honeybees: Biological characteristics, urban nesting behavior and accidents caused in Brazilian cities (Hymenoptera: Apidae)
(2005-12-12)
In 1956 African honeybee queens (Apis mellifera scutellata) were imported from South Africa and Tanzania to Brazil, as part of a government project to increase Brazilian honey production. The European honeybees existing ...
Effects of Natural Infestations of the Mite Varroa destructor on the Development of Africanized Honeybee Workers (Apis mellifera)
(California State University, 2011-01-01)
The mite Varroa destructor (Anderson & Treuman 2000) has caused extensive damage to beekeeping worldwide. In Brazil, weather conditions and the strains of bees do not provide ideal conditions for mite parasitism, which is ...
Jelleines: a family of antimicrobial peptides from the Royal Jelly of honeybees (Apis mellifera)
(Elsevier B.V., 2004-06-01)
Four antimicrobial peptides were purified from Royal Jelly of honeybees, by using reverse phase-HPLC and sequenced by using Q-Tof-MS/MS: PFKLSLHL-NH2 (Jelleine-I), TPFKLSLHL-NH2 (Jelleine-II), EPFKLSLHL-NH2 (Jelleine-III), ...
Analysis of Mortality in Africanized Honey Bee Colonies with High Levels of Infestation by Varroa destructor
(California State University, 2012-01-01)
The mite Varroa destructor (Anderson & Treuman 2000) is one of the world's most important plagues of apiculture. In Brazil this mite does not encounter good conditions for parasitism because weather conditions are not ideal ...
Effects of sublethal dose of fipronil on neuron metabolic activity of africanized honeybees
(2013-04-01)
Fipronil is a neurotoxic insecticide that inhibits the gamma-aminobutyric acid receptor and can affect gustative perception, olfactory learning, and motor activity of the honeybee Apis mellifera. This study determined the ...
Influence of the collection methodology on the Apis mellifera venom composition: Peptide analysis
(2006-06-07)
Differences of venom peptide composition as function of two collection methodologies, electrical stimulation (ES) and reservoir disruption (RD), were analyzed by reverse-phase HPLC in Apis mellifera races - A. m. adansonii, ...
Bioinsecticide action of the venom of Africanized bees Apis mellifera Linnaeus 1758 (Hymenoptera: Apidae): I - The most susceptible age of Diatraea saccharalis Fabricius 1794 (Lepeletier: Pyralidae) eggs to the venom action
(1996-01-01)
The present paper aimed at testing the action of non-lyophilized venom of Africanized bees Apis mellifera through topical applications on Diatraea saccharalis egg masses. The CL50, DL50 and the most susceptible age of eggs ...
BIOCHEMICAL VARIABILITY BETWEEN VENOMS FROM DIFFERENT HONEYBEE (APIS-MELLIFERA) RACES
(Elsevier B.V., 1993-10-01)
1. The comparison of molecular exclusion cromatography profiles of venoms from sting apparatuses of Apis mellifera ligustica, Apis mellifera adansonii and Africanized honey-bees in Sephadex G-100 revealed both qualitative ...
Profiling the proteome complement of the secretion from hypopharyngeal gland of Africanized nurse-honeybees (Apis mellifera L.)
(Elsevier B.V., 2005-01-01)
The protein complement of the secretion from hypopharyngeal gland of nurse-bees (Apis mellifera L.) was partially identified by using a combination of 2D-PAGE, peptide sequencing by MALDI-PSD/MS and a protein engine ...
