Synergistic effect of honeybees and wild floral visitors in promoting sweet cherry fruit set in central Chile

Biological Research
Background Recent evidence highlights the key role of wild insects as pollinators in agroecosystems, enhancing fruit set in crops such as sweet cherry (Prunus avium). In Chile, the contribution of wild insects to crop yield remains poorly understood, and

Las razones de por qué Chile debe detener la importación del abejorro comercial Bombus terrestris (Linnaeus) y comenzar a controlarlo

Gayana, 2018
La crisis mundial de polinización no solo es producida por la pérdida de polinizadores, sino también por su homogeneización, ambos procesos causados por el ser humano. En este documento analizamos los impactos ecológicos que justifican la prohibición de

Cloning, Expression, Sequence Analysis and Homology Modeling of the Prolyl Endoprotease from Eurygaster integriceps Puton [PDF]

, 2014
Eurygaster integriceps Puton, commonly known as sunn pest, is a major pest of wheat in Northern Africa, the Middle East and Eastern Europe. This insect injects a prolyl endoprotease into the wheat, destroying the gluten.

Light Sensitive Bumblebee Species Are Associated With Forest Habitat and Forest‐Dominated Landscapes

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Bumblebee species and bumblebee communities with high light sensitivity are more common and abundant in forest habitats and forested landscapes. Bumblebees with higher light sensitivity tend to forage on plants with greater shade tolerance. Our results suggest that visual adaptations for light sensitivity contribute to shaping bumblebee species ...

Air pollution modifies colonisation factors in beneficial symbiont Snodgrassella and disrupts the bumblebee gut microbiome

npj Biofilms and Microbiomes
Particulate air pollutants, a major air pollution component, are detrimental to human health and a significant risk to wildlife and ecosystems globally. Here we report the effects of particulate pollutant black carbon on the beneficial gut microbiome of ...

Regular periods of abdominal contractions recorded from larvae of the bumblebee, Bombus terrestris (Hymenoptera: Apidae)

European Journal of Entomology, 2006
Using an opto-cardiograph combined with an infrared gas analyzer regular bouts of abdominal contractions were recorded from last instar larva of Bombus terrestris. The rate of CO2 release was about 0.7 ml g-1 h-1.

Evolution of Phospholipase A2 in Bees and Flies

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study investigated the evolution of the PLA2 gene in bees and flies and compared the evolutionary rate between them, which denotes the toxic group and the non‐toxic group. The results showed that PLA2 was under purifying selection and that an accelerated evolution of PLA2 occurred in the toxic group when compared with the non‐toxic group ...

Do bumblebees have signatures? Demonstrating the existence of a speed-curvature power law in Bombus terrestris locomotion patterns.

PLoS ONE, 2020
We report the discovery that Bombus terrestris audax (Buff-tailed bumblebee) locomotor trajectories adhere to a speed-curvature power law relationship which has previously been found in humans, non-human primates and Drosophila larval trajectories.

A high‐throughput and sensitive method for food preference assays in the argentine ant

Pest Management Science, Volume 81, Issue 10, Page 7210-7218, October 2025.
A high‐throughput and sensitive method for food preference assays in the Argentine ant. The dual feeder detects dispreference for food with low levels of an aversive compound (quinine) and preference for foods with higher levels of phagostimulants (sucrose).

Lower bumblebee colony reproductive success in agricultural compared with urban environments [PDF]

, 2018
Urbanization represents a rapidly growing driver of land-use change. While it is clear that urbanization impacts species abundance and diversity, direct effects of urban land use on animal reproductive success are rarely documented.
