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.

Nasonov pheromone of the honeybee - apis-mellifera-l (hymenoptera, apidae) .4. Comparative electroantennogram responses

, 1982
Electroantennogram (EAG) responses from worker honeybee antennae were obtained for each Nasonov component. Response amplitudes to 10 μg of components correlated well with reported relative abilities to attract foragers in the field.

Knockout of a single Pax6 gene (toy but not ey) leads to compound eye deficiency and small head in honeybees

Communications Biology
The compound eyes are crucial to honeybees, playing pivotal roles in color recognition, orientation, localization, and navigation processes. The development of compound eyes is primarily mastered by an evolutionarily conserved transcription factor Pax6 ...

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 ...

Honey Bee Pollination of Camellia oleifera and Mitigation of Toxic Crop Nectar

Insects
Tea oil tree (Camellia oleifera), a woody oil crop native to Southern China, relies on insect pollination for fruit and seed production. However, its nectar is toxic to honey bees (Apis spp.) due to their inability to digest the oligosaccharide present ...

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.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect 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

Using synthetic pheromone lures to attract honeybee colonies in Kenya.

, 1986
Nasonov pheromone lures, either with or without (E)-9-oxo-2-decenoic acid (902), were hung inside empty Kenya top-bar hives in each of 4 apiaries in Kenya.
