Pest‐preservation paradox among insects

open access: yesConservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

The Polar Resources Ice Mining Experiment-1 (PRIME-1) Payload Operations Summary from the IM-2 Mission

open access: yesThe Planetary Science Journal
The Polar Resources Ice Mining Experiment-1 (PRIME-1) payload was designed to aid in NASA’s Lunar In-Situ Resource Utilization (ISRU) technology development program. It was proposed for resource reconnaissance, identifying and quantifying volatiles up to

BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring

open access: yesEntomologia 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.

Reconsidering the Selection Strategy in a Flemish Honey Bee Breeding Program: Towards Selection by Exclusion

open access: yesInsects
Selective breeding is widely used to improve honey bee health and colony performance, commonly applying selection based on colony traits. Since 2017, a mass selection program in Flanders, Belgium, has ranked queens according to resilience, productivity ...

Geographic Classification of Social Bees Using Automated Wing Pattern Analysis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We present an end‐to‐end deep learning framework for automated geographic classification of honey bee populations based on wing morphology. A dataset of 1040 wing images from seven regions was analyzed using four CNN architectures with transfer learning.

Evaluation of 10-Year Selection for Virus Resistance in a Mass Breeding Program

open access: yesInsects
Viral infections pose a major threat to honey bee health. While viruses are typically controlled indirectly through efforts of attaining Varroa resistance, the heritable trait suppressed in ovo virus infection (SOV) provides a direct avenue for selecting

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

open access: yesEcological 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

open access: yesThe 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.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

open access: yesIbis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial
