Honey bees (Apis mellifera) are prominent crop pollinators and are, thus, important for effective food production. The honey bee gut microbiota is mainly host specific, with only a few species being shared with other insects. It currently remains unclear how environmental/dietary conditions affect the microbiota within a honey bee population over time. Therefore, the aim of the present study wa...

Thecarpenterbee,Xylocopavirginica(L.), acts as aprimarynectar thief in southeastern plantations of native rabbiteye blueberry, Vaccinium ashei Reade, perforating corollae laterally to imbibe nectar. Honey bees, Apis mellifera L., learn to collect nectar from these perforations and thus become secondary thieves. We conducted a 2-yr study to assess how nectar robbing in honey bees affects fruit p...

A total of 3917 honey samples and 119 'bee pollen' samples (pollen collected by honeybees) were analysed for pyrrolizidine alkaloids (PAs). Some 0.05 M sulphuric acid was used for extraction followed by a clean-up step by means of solid-phase extraction. Separation and detection was achieved by target analysis using an LC-MS/MS system. PAs were found in 66% of the raw honeys (bulk honey not yet...

A study was conducted in 2006 and 2007 designed to examine the foraging range of honey bees, Apis mellifera (Hymenoptera: Apidae), in a 15.2 km(2) area dominated by a 128.9 ha glyphosate-resistant Roundup Ready® alfalfa seed production field and several non-Roundup Ready alfalfa seed production fields (totaling 120.2 ha). Each year, honey bee self-marking devices were placed on 112 selected hon...

Community service is a process of self-empowerment for the benefit society. This based on problems that occur in community potential existing honey has not been optimized to become superior product. In addition, honey-producing bee farmers only produce one product, namely real honey. Gradually, this product certainly less attractive consumers even though production keeps continue. Therefore, it...

the carob moth, ectomyelois ceratoniae zeller (lep.: pyralidae) is the most important pest of pomegranate orchards in iran. this current research was carried out to study the biology of venturia canescens gravenhorst (hym.: ichneumonidae) as one of its larval parasitoids. laboratory studies were conducted on the immature developmental time, adult longevity, functional response, parasite progeny...

This study was conducted to determine the effect of increased propolis production on overall hive profitability and productivity. The study took place near George situated in the Southern Cape region of South Africa. Standard Langstroth hives were used (n = 12) containing honeybee colonies of equal strength from the species Apis mellifera capensis. Propolis production in colonies equipped with ...

Honey bees (Apis mellifera) play a critical role in global food production as pollinators of numerous crops. Recently, honey bee populations in the United States, Canada, and Europe have suffered an unexplained increase in annual losses due to a phenomenon known as Colony Collapse Disorder (CCD). Epidemiological analysis of CCD is confounded by a relative dearth of bee pathogen field studies. T...
