This experiment was carried out to evaluate the effect of honeybee pollination in production and quality soybean seeds (Glycine max L. Merril). Seed higher (P=0.0001) covered areas with colonies (50.64%) uncovered (57.73%) than without colonies. It could be concluded that honeybees were responsible for 95.5% accomplished by insects. The pod number treatment 61.38% (P=0.0002) honeybees. average weight 100 larger area honeybees, reached 17.8 g. medium content crude protein grains 36.7% oil...

Traditionally, melissopalynological and physicochemical analyses have been the most used to determine botanical origin of honey. However, when performed individually, these may provide less unambiguous results, making it difficult discriminate between mono multifloral honeys. In this context, with aim better characterizing beehive product, a selection 112 Lavandula spp. monofloral honey samples from several regions were evaluated by association multivariate statistical techniques...

Abstract The neonicotinoid thiamethoxam is widely used in different agricultural crops, and it has a spectrum of action against insects, affecting both pests pollinators, such as bees. In this study, the effects exposure to sublethal concentrations on stingless bees Scaptotrigona bipunctata were evaluated. Foragers exposed insecticide subjected genetic biochemical, histochemical, morphological analyses after 24, 48, 72 h ingestion. Analysis isoenzyme esterases revealed significant...

Abstract Bees are essential pollinators that contribute to maintaining biodiversity and increasing agricultural production. However, by foraging on crops, bees may become contaminated with compounds used for pest control. In this study, we exposed bee ( Apis mellifera L.) colonies the insecticide imidacloprid (IMD) under field conditions assess occurrence of oxidative stress in larvae pupae investigate morphological changes fat body midgut adult bees. The apiary area was divided into three...

As famílias poliafetivas desafiam o conceito tradicional de família e trazem à tona questões éticas legais. No Brasil, reconhecimento legal dessas como entidades familiares é uma necessidade, pois a legislação vigente não aborda completamente suas especificidades direitos. Além disso, reconhecer diversidade afetiva promove respeito dignidade humana pluralidade nas formas amar constituir família. O objetivo deste artigo foi discutir, através da pesquisa qualitativa, baseada em levantamento...

Bee colony health is declining as a result of several factors, including exposure to pesticides. The development and strength honey bee colonies depend on the reproductive success queen bees. Because flowers are sources food for bees, foragers can accidentally collect carry contaminated pollen nectar their hives; this may compromise longevity life span individuals. Thus, present study aimed observe action imidacloprid in midgut ovaries Apis mellifera queens, well effects sperm stored...

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...

Tetragonisca angustula and T. fiebrigi esterases were biochemically characterized by their inhibition pattern thermostability. Workers of both species collected from nests at the State University Maringa. In three observed: EST-1 (β-esterase, cholinesterase I), EST-2 (α-esterase, II) EST-4 (αβ-esterase, carboxylesterase). two detected: EST-3 acetylesterase) e showed highest thermostability, it was not observed above 54°C, while in EST- 1 detected 52°C. Through this characterization, that...

Genetic and phenotypic parameters for hygienic behavior, invasion infestation rates, total effective reproduction of Varroa destructor in Africanized honeybee colonies producing honey (20 hives) or royal jelly (30 mini-hives) were analyzed. The significance monthly fixed effects, type product (honey jelly) their interactions verified through generalized linear model procedures. Software WinBugs (Bayesian Inference Using Gibbs Sampling) with Bayesian inference was employed (co)variance...

In this study, performed in the western part of state Paraná, Brazil, two self-fertile hybrid commercial rapeseed genotypes were evaluated for yield components and physiological quality using three pollination tests spanning sowing dates. The treatments consisted combinations (Hyola 61 Hyola 433), (uncovered area, covered area without insects containing a single colony Africanized Apis mellifera honeybees) dates (May 25th, 2011 June 2011). presence honeybees during flowering time increased...

This research was carried out to evaluate the pollination by Africanized honeybees Apis mellifera, floral biology and observe hoarding behavior in soybean flowers (Glycine max Merril), var. BRS-133. The treatments were constituted of demarcated areas for free visitation insects, covered cages with a honeybee colony (A. mellifera) also cage without insects visitation. All had 24 m² (4m x 6m). stayed open larger time (82.82 ± 3.48 hours) area honeybees. stigma more receptive (P=0.0021) (87.3...

This research was carried out to evaluate the effect of proteic supplement on royal jelly production in honeybee colonies and its correlation with environmental variables. The treatments were: that had received a diet formulated 35% crude protein, commercial did not receive protein diet. There no difference (p > 0.05) among for parameters production. average each variable was: amount accepted larvae, 8.56 ± 6.76; acceptance percentage, 29.20 22.03%; produced per colony, 1.83 0.82 g; cup,...

Genetic and phenotypic parameters considering the genetic effect on hygienic behavior of queen workers from 40 Africanized honeybees colonies were estimated separately. Maternal origin queens was controlled whereas paternal unknown, different groups considered in three seasons, October 2006, April 2007 August 2007, but with same queen. Colonies 21 honey producers 19 royal jelly producers. After method freezing capped brood, determined by ratio between number dead brood removed at 24, 48 72...

The aim of this study was to carry out a survey the flora with potential for beekeeping in counties Ubiratã and Nova Aurora-PR through collection plants pollen analyses honey samples collected monthly. 208 species were recorded, distributed 66 families. families that showed major richness types were: Asteraceae, Myrtaceae Solanaceae. Approximately 80 found samples, most them characterized as heterofloral. Cultivated plants, such Glycine max (soybean) Eucalyptus spp., representative some...

Investigations were carried out to evaluate Africanized and Carniolan hybrid Apis mellifera honeybees in royal jelly production. Ten colonies randomly collected nature housed Langstroth beehives. Each hive was having two nuclei with five frames. In superior nucleus frame containing 28 acrylic cups bars. The the best production remained experiment their queens replaced by respective daughters. placed lower showed a higher (P=0.0001) of per colony, three-day collect (3.95 ± 2.92 g) when...

It is important to select the best honeybees that produce royal jelly identify molecular markers, such as major proteins (MRJPs), and hence contribute development of new breeding strategies improve production this substance.Therefore, study focused on evaluating genetic variability mrjp3, mrjp5, mrjp8 associated allele maintenance during process selective reproduction in Africanized Apis mellifera individuals, which were chosen based production.The three loci analyzed polymorphic, produced a...

Eight sunflower genotypes were analyzed to estimate correlation values for nine agronomic traits. Path analysis was used partition the into direct and indirect effects on seed yield in two pollination tests (open restricted pollination). In both tests, there significant (p<0.05) positive between head diameter, mass, number mass of achenes per first last count germination. There no (p≥0.05) 1000 weight tests. Oil content not correlated with open pollination, but it positively plants. The path...
