The aim of this research was to analyze and compare 17 honey samples, 11 organic six non-organic Apis mellifera honey. samples were analyzed concerning moisture, hydroxymethylfurfural, diastase index, water activity, color, total sugar, reducing sucrose, ash, viscosity, electrical conductivity, pH, acidity, formol index. With the exception sugar averages other parameters different between two groups. All presented moisture values 23.50 24.40%. Among nonorganic apparent sucrose amount upper...

The present study determined the genetic variation at mrjps loci (mrjp3, mrjp5 and mrjp8) evaluated potential use of MRJPs as molecular markers for higher royal jelly production in Africanized honeybee colonies. three analyzed produced a total 17 alleles. This high allelic polymorphism indicated these could serve markers. was by analyses multiple linear regressions with EPD (expected progeny differences) values production. variance that mrjp3 repetitive region influenced value queen's...

As for...

This study was carried out to evaluate the effect of supplements with isolated soy protein, brewer's yeast, a mixture protein linseed oil, palm oil and in royal jelly production Africanized honey bee colonies. Total produced superior (P < 0.05) colonies that were fed yeast (11.68g/colony), followed by (11.30g/colony) (9.61g/colony), latter higher than controls I (6.35g/colony), II (6.95g/colony). Thus, mixed are viable optimize this beekeeping activity commercial scale.

This study was carried out to evaluate the financial viability of five supplements made with different sources oil and protein, be given Africanized honeybees for royal jelly production. The verified whether investments colony supplementation give returns beekeepers, increasing profits diversification bee products. In order supplements, two experimental assays were performed. each, 20 colonies distributed randomly in four treatments, 15 replications per colony. assay I, treatments were:...

This study aimed to analyze biometric parameters and productive stingless bee colonies mandacaia (Melipona quadrifasciata anthi-dioides) in consecutive generations. Sixty from different regions of Bahia state were transferred INPA boxes model. After 90 100 days the evaluated divided, forming first later second generation. In every generation colony measurement (brood, honey pollen pots), queen glossa workers morphometry. The weight physogastric length did not differ between There differences...

Os objetivos deste trabalho foram estimar componentes de variância genética aditiva, fenotípica e residual a herdabilidade para características relacionadas com produção mel estrutura do ninho abelhas Melipona quadrifasciata anthidioides. Sessenta colônias diferentes regiões da Bahia transladadas caixas padronizadas modelo INPA divididas, originando as gerações parentais G1 G2. Foram medidas características: estimativa mel; número, largura, volume altura dos potes diâmetro pólen; peso;...

This experiment was carried out to evaluate the effects of replacing corn by high tannin sorghum in diets japanese quails (Coturnix coturnix japonica) on performance and egg quality. Two hundred fifty-two with 50 weeks age were evaluated during four periods 21 days. The treatments consisted containing 20, 40, 60, 80 100% sorghum, a control treatment (100% corn). Diets formulated so that levels energy, protein, amino acids (methionine+cystine lysine), calcium phosphorus similar A completely...

The objective of this study was to verify the flight radius and influence climatic season period day on external activity Melipona rufiventris bees. forager bees were released at different distances evaluate radius. following considered for activities in four seasons year (Winter, Autumn, Spring, Summer): entry with no apparent load as nectar/water, defined opaque mass corbicula pollen, undefined shiny resin/clay or bee exit removal debris, trapped by jaws. Assessments performed between 6 am...

In meliponini colonies, biometric characteristics may be associated with production traits, thus the study of correlations is extremely useful as a tool for colony selection process. The aim this was to estimate between and productive parameters Melipona quadrifasciata anthidioides. We analyzed 128 from 60 parental two generations, F1 F2. following were evaluated: queen weight; number, length width brood disks; width, depth volume honey pots; pollen glossa size, population production. weight...

The biodiversity of bees in the world is very large. They are known about 20,000 species. Bees main pollinators and crucial for many crops, contribute to conservation plant biodiversity. Many plants economic importance rely on these pollinating insects, which increased production fruits seeds. beekeeping has emerged as one few animal husbandry activities that cause low environmental impact while providing a rapid return invested capital. High mortality rates disappearance leaving at risk...

O girassol (Helianthus annuus  L.) e uma planta de polinizacao cruzada  os seus principais polinizadores sao as abelhas. Com a por insetos o produz sementes, sendo abelha africanizada  Apis mellifera  L. agente mais efetivo. A  performance desta como polinizadora depende varios fatores, eles, disponibilidade polen nectar na flor, condicoes climaticas aspectos fisicos do solo. pouco sensivel variacoes no fotoperiodo, fato este que permite seu escalonamento producao em quase todo territorio...
