Antagonistic Effect of Gut Bacteria in the Hybrid Carniolan Honey Bee, Apis Mellifera Carnica, Against Ascosphaera Apis, the Causal Organism of Chalkbrood Disease

open access: yesJournal of Apicultural Science, 2014
The objective of this study was to isolate and characterize bacterial strains associated with the gut of the hybrid Carniolan honey bee, Apis mellifera carnica, and to determine their in vitro and in vivo potential against Ascosphaera apis, the causal ...

Complex population structure and haplotype patterns in the Western European honey bee from sequencing a large panel of haploid drones

open access: yesMolecular Ecology Resources, Volume 22, Issue 8, Page 3068-3086, November 2022., 2022
Abstract Honey bee subspecies originate from specific geographical areas in Africa, Europe and the Middle East, and beekeepers interested in specific phenotypes have imported genetic material to regions outside of the bees' original range for use either in pure lines or controlled crosses.

Identification of 121 variants of honey bee Vitellogenin protein sequences with structural differences at functional sites

open access: yesProtein Science, Volume 31, Issue 7, July 2022., 2022
Abstract Proteins are under selection to maintain central functions and to accommodate needs that arise in ever‐changing environments. The positive selection and neutral drift that preserve functions result in a diversity of protein variants. The amount of diversity differs between proteins: multifunctional or disease‐related proteins tend to have ...

Evaluation of the risks for animal health related to the presence of hydroxymethylfurfural (HMF) in feed for honey bees

open access: yesEFSA Journal, Volume 20, Issue 4, April 2022., 2022
Abstract The European Commission has asked the EFSA to evaluate the risk for animal health related to the presence of hydroxymethylfurfural (HMF) in honey bee feed. HMF is a degradation product of particular sugars and can be present in bee feed. HMF is of low acute toxicity in bees but causes increased mortality upon chronic exposure. A benchmark dose

The role of insect pollinators in avocado production: A global review

open access: yesJournal of Applied Entomology, Volume 145, Issue 5, Page 369-383, June 2021., 2021
Abstract Insect pollination increases the yield and quality of many crops and therefore, understanding the role of insect pollinators in crop production is necessary to sustainably increase yields. Avocado Persea americana benefits from insect pollination, however, a better understanding of the role of pollinators and their contribution to the ...
