Metabolisation of thiamethoxam (a neonicotinoid pesticide) and interaction with the Chronic bee paralysis virus in honeybees.

open access: yesPesticide Biochemistry and Physiology, 2017
Pathogens and pesticides are likely to co-occur in honeybee hives, but much remains to be investigated regarding their potential interactions. Here, we first investigated the metabolisation kinetics of thiamethoxam in chronically fed honeybees.

Glyphosate-Based Herbicides and Their Potential Impact on the Microbiota of Social Bees

open access: yesToxics
Bee pollination is essential for terrestrial ecosystems and crop production. However, the species richness of wild bees and other pollinators has declined over the past 50 years, with some species experiencing dramatic decreases.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study

open access: yesAllergy, EarlyView.
Venom immunotherapy (VIT) during pregnancy, when maintenance dose is well tolerated, can be continued. No increased risk of adverse effects to VIT or safety concerns for the pregnancy or the newborns were observed. No decreased efficacy of VIT, in case of re‐stings, was reported.

The amino terminal domain of the human α7 nicotinic acetylcholine receptor subunit leads to the functional expression of human/insect receptors

open access: yesBritish Journal of Pharmacology, EarlyView.
Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.

Frontiers of Genetic Engineering: Cutting-Edge Genome Editing for Silkworms and Honeybees

open access: yesScientific Papers Animal Science and Biotechnologies
Nowadays, entomology is one of the most studied domains due to the pivotal role of insects in ecology, agriculture, the pharmaceutical industry, and medicine.

No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

open access: yesEcological Entomology, EarlyView.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

Non-Apis (Bombus terrestris) versus honeybee (Apis mellifera) acute oral and contact sensitivity – Preliminary results of ECPA company data evaluation

open access: yesJulius-Kühn-Archiv, 2018
A preliminary data evaluation was conducted by ECPA companies to compare the sensitivity of bumblebees (Bombus terrestris) with the sensitivity of honeybees (Apis mellifera).

Disease associations between honeybees and bumblebees as a threat to wild pollinators

open access: yesNature, 2014
Emerging infectious diseases (EIDs) pose a risk to human welfare, both directly and indirectly, by affecting managed livestock and wildlife that provide valuable resources and ecosystem services, such as the pollination of crops.
