Résumé :

Forager bees forage long distances in search of food resources, which leaves them susceptible to oxidative stress, with an accumulation of reactive oxygen species (ROS) that affect their longevity and cognitive capacity, an effect aggravated by pesticides exposure. The aim of this study is to evaluate the toxicity of different classes of pesticides: herbicide (glyphosate), insecticide (fipronil and imidacloprid) and fungicide (pyraclostrobin) on the gene expression profile of the antioxidant system of bees in the forager phase, using transcriptome analysis. For this purpose, bees over 21 days

Résumé :

Honey bees,Apis mellifera, face major challenges including diseases and reduced food availability due to agricultural intensification. Additionally, migratory beekeeping may subject colonies to a moving stress, both during the move itself and after the move, from the bees having to forage in a novel environment where they have no knowledge of flower locations. This study investigated the latter. We moved three colonies housed in observation hives onto the campus from a site 26 km away and compared their foraging performance to three similarly sized colonies at the same location that had not be

ABSTRACTThe effect sublethal concentrations (¼ and ½ of LC50 at 96 hrs.) of biopesticide neem oil – 25 EC was studied on the forager bees (25 days old worker bees) of Italian honeybee Apis mellifera L. The results indicated that there were no significant alteration in total amino acid contents in forager bees at either sublethal concentration level-1(¼ of LC50 at 96 hrs) or concentration-2 (½ of LC50 at 96 hrs.) of neem oil treated bees over control bees. Although field experiments are inevitable for further confirmations of lethality of neem oil on honeybees.

Protein-supplemented artificial diets are widely used by beekeepers during winter and whenever food availability is low, yet no data are available concerning their effects on bees’ health. In this work, the effects of two commercial diets enriched with 1.7% and 7.7% protein concentration on feed intake, survival rate, glucose oxidase, phenoloxidase and glutathione S-transferase in newly emerged and forager bees were tested. Administration of a 7.7% protein-enriched diet significantly reduced the lifespan of both newly emerged and forager bees, while only in foragers a significantly higher feed

Nosema apis and Nosema ceranae are responsible for nosemosis in the honey bee (Apis mellifera). The aim of the study was to identify Nosema spp. during the honey flow season in bee colonies, for co-infection or no infection with Nosema apis/Nosema ceranae. Hive bees, forager bees, pollen grains brought by them, and bee bread were analysed. In the infected group, 12 of 30 samples of hive bees were infected with Nosema ceranae, 7 were co-infected, 3 were infected with Nosema apis.

Résumé :

Background.The age of an insect strongly influences many aspects of behavior and reproduction. The interaction of age and behavior is epitomized in the temporal polyethism of honey bees in which young adult bees perform nurse and maintenance duties within the colony, while older bees forage for nectar and pollen. Task transition is dynamic and driven by colony needs. However, an abundance of precocious foragers or overage nurses may have detrimental effects on the colony. Additionally, honey bee age affects insecticide sensitivity. Therefore, determining the age of a set of individual honey be

Based on bee foraging behaviour, the Bees Algorithm (BA) is an optimisation metaheuristic algorithm which has found many applications in both the continuous and combinatorial domains. The original version of the Bees Algorithm has six user-selected parameters: the number of scout bees, the number of high-performing bees, the number of top-performing or “elite” bees, the number of forager bees following the elite bees, the number of forager bees recruited by the other high-performing bees, and the neighbourhood size. These parameters must be chosen with due care, as their values can impact the

Résumé :

AbstractRecent concerns regarding potential effects of pesticides on pollinators have prompted regulatory agencies to estimate dietary ingestion rates for honey bees (Apis mellifera). The task is difficult because of the complex caste and food storage systems in honey bee colonies. Considerable data on the nutrition and energetics of honey bees have recently been collated. These data were used to parameterize a probabilistic model estimating nectar requirements of nectar foragers. Median estimates were more than 6× lower than the recommended median value from the North American government agen

Résumé :

Circadian rhythms of about a day are ubiquitous in animals and considered functionally significant. Honey bees show remarkable circadian plasticity that is related to the complex social organization of their societies. Forager bees show robust circadian rhythms that support time-compensated sun-compass navigation, dance communication and timing visits to flowers. Nest-dwelling nurse bees care for the young brood around the clock. Here, we review our current understanding of the molecular and neuroanatomical mechanisms underlying this remarkable natural plasticity in circadian rhythms.

Today, ranchers and farmers are faced with various governmental regulations as well as fluctuating grain and fuel prices. While beef may still be a commodity, it can be sold in specialized markets, in markets that have enhanced consumer demand. It is nearly impossible for a producer with a small herd to compete with a larger ranch if they are selling their cattle as a commodity. The primary economic objective of the producer is to

Eight Hereford steers were fitted with total fecal collection bags and fed four diets with a low P grass hay and supplemented with increasing amounts of a mineral source of P, dicalcium phosphate. Dietary DM P concentrations were 0.10 (no P supplementation), 0.23, 0.34, and 0.45% P.

AbstractRangeland wildlife ecology and conservation is strongly influenced by domestic livestock systems. Domestic livestock production on rangelands in North America is dominated by ruminant livestock, with beef cattle being the largest industry. Rangeland ruminant livestock production systems are unique in that land/animal managers develop production systems that attempt to optimize the use of limited-nutrition forage bases. This involves the strategic selection of calving/lambing dates to coincide with forage resources and labor limitations. Likewise, the species, breed, and age of animal i

Résumé :

The Argentine ant (Linepithema humile) is an invasive species first identified in New Zealand in 1990. It is an aggressive tramp species that can form very large ‘super colonies’ extending over vast areas and has been reported to rob honey and predate honey bees in hives. This pilot study sought to establish, from a circulated survey of beekeepers, which ant species were present in their hives and what awareness the beekeepers had of the potential impact of Argentine ants. In addition, a simple method of quantifying the effects of the Argentine ant on brood abundance was trialled in the field.

Résumé :

Leguminous forage crops are high in proteins but deficient in S- amino acids. It has been shown that both wool quality and milk production can be limited by the post-ruminal supply of sulfur-containing amino acids. Efforts to use conventional plant breeding and cell selection techniques to increase the S-amino acid content of alfalfa have met with little success. With the objective to increase the S-amino acid content of forage legumes, the goal of this project was to co- express the methionine rich zein genes from corn along with a gene for a key enzyme in methionine biosynthesis, aspartate k
