Genetic parameters for weight, morphometry and oviposition of Africanized honeybee queens using simulated data

This study aimed to estimate genetic parameters for simulated data of body weight (BW), abdominal width (AW), abdominal length (AL), and oviposition. Simulation was performed based on real data collected at apiaries in the region of Campo das Vertentes, Minas Gerais, Brazil. Genetic evaluations were perf...

Accediendo al pasado: uso de especímenes de colección como fuentes de información genética para el género Bombus (Hymenoptera: Apidae)

Rev. biol. trop; 68 (2), 2020
Introducción: Recientemente ha tomado relevancia el uso de especímenes de museo como fuente de información genética para desarrollar estudios que resuelven preguntas taxonómicas, ecológicas, demográficas y evolutivas a diversas escalas temporales y geográficas. Sin embargo, material genético obt...

Correlação de parâmetros biométricos e produtivos em colônias de Melipona scutelaris

The objective of this research was to estimate the correlations between the biometric and reproductive parameters of Melipona scutelaris. Four collections were performed with 30-day intervals, consisting of the evaluation of each colony, considering the following parameters: honey pot size and volume (HP...

Energetic supplementation for maintenance or development of Apis mellifera L. colonies

The nutritional requirements of honeybees (Apis mellifera) for their complete development need to be supplied through food sources available in the environment, since honeybees are insects that depend directly on blossoming food sources. However, at certain times a food-supply reduction can promote nutri...

Pollination service of Nannotrigona testaceicornis stingless bees in strawberry

Arq. Inst. Biol; 87 (), 2020
Strawberry presents moderate dependence on bee pollination service, and pollination is related to the production and quality of fruits. The aim of this study was to evaluate the pollination service provided by Nannotrigona testaceicornis stingless bees in strawberry. Primary flowers of cultivar San Andre...

Exposure of Apis mellifera (Hymenoptera: Apidae) to pollen grains of soybean plants (Glycine max L) originated from treated seeds

Arq. Inst. Biol; 87 (), 2020
Residues of plant protection products have been reported in floral resources such as pollen, but the potential risks of pollinator exposure are still unclear. Therefore, studies are needed to assess the risk of exposure/intoxication of bees, as they collect these resources to maintain their colony. The p...

Determinación del porcentaje de miel de flores y miel de mielada comercializadas en supermercados de la ciudad de La Paz

Con-ciencia (La Paz); 8 (2), 2020
INTRODUCCIÓN: la miel, consumida por el hombre desde hace miles de años debido a sus propiedades organolépticas y terapéuticas, es el producto de la unión entre el mundo animal, la abeja (apis melífera), y el vegetal, el néctar de las flores y/o secreciones azucaradas de las plantas o insectos. En...

Epidemiology of envenomation by Africanized honeybees in the state of Rio Grande do Norte, Northeastern Brazil

ABSTRACT: Introduction: In the American continent, accidents caused by honeybees are a public health problem due to the high incidence and severity of the cases. Despite its medical importance, there are few epidemiological studies on this topic in Brazil, especially referring to the Northeastern state...

Contribution of molecular diagnosis to bee venom allergic patients with systemic reactions during the build-up phase of bee venom immunotherapy

Introduction: Bee venom (BV) allergy is one of the most common causes of severe anaphylaxis. Venom immunotherapy (VIT) is considered the most effective treatment, but systemic reactions may occur. This study aimed to characterize the sensitization profile by molecular components of patients with BV anaph...
