Identification of Parasitic Infections by Analyzing Honeybees, Honey, and Pollen Using Droplet Digital RT-PCR

Microorganisms
Toxoplasma gondii, Giardia intestinalis, and Cryptosporidium spp. are common pathogens that contaminate water and food. They can pose serious health risks, especially to vulnerable groups like immunocompromised individuals, pregnant women, young children,

Addition and subtraction by honeybees [PDF]

Learning & Behavior, 2019
Howard, Avargues-Weber, Garcia, Greentree, and Dyer (Science Advances, 5,1-6, 2019) report experiments in which honeybees initially shown a number of shapes could subsequently choose a pattern that added or subtracted one from that number. Further, the operations of addition and subtraction were cued by the colors of the shapes.

Safety of Venom Immunotherapy in Pregnancy: A Multicentre Study

Allergy, 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.

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

Toxics
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.

Impacts of a Sweet Orange Essential Oil–Based Biopesticide on Exorista larvarum, a Parasitoid Tachinid Fly With a Dual Role

Entomologia Experimentalis et Applicata, EarlyView.
Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.

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

Julius-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).

BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring

Entomologia Experimentalis et Applicata, EarlyView.
We present a bumblebee colony monitoring system, BumbleBEEP. The system is fitted with thermometers and a custom weight sensor. These record data up to every 15 min, recording bumblebee brood nest temperature, environmental ambient temperature, and colony growth.

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.
