Effects of Heat Stress on Mating Behavior and Colony Development in Bombus terrestris (Hymenoptera: Apidae)

open access: yesFrontiers in Ecology and Evolution, 2021
Climate change is related to an increase in the frequency and intensity of extreme events such as heatwaves. In insect pollinators, heat exposure is associated with direct physiological perturbations, and in several species, could lead to a decrease of ...

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Immune priming of honey bees protects against a major microsporidian pathogen

open access: yesPest Management Science, EarlyView.
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Mating Stimulates the Immune Response and Sperm Storage-Related Genes Expression in Spermathecae of Bumblebee (Bombus terrestris) Queen

open access: yesFrontiers in Genetics, 2021
Bumblebee queens have remarkable spermathecae that store sperm for year-round reproduction. The spermathecal gland is regarded as a secretory organ that could benefit sperm storage.

Wild bee toxicity data for pesticide risk assessments [PDF]

open access: yes, 2019
Pollination services are vital for agriculture, food security and biodiversity. Although many insect species provide pollination services, honeybees are thought to be the major provider of this service to agriculture. However, the importance of wild bees

Vector navigation in walking bumblebees

open access: yesCurrent Biology, 2022
Path integration is a computational strategy that allows an animal to maintain an internal estimate of its position relative to a point of origin. Many species use path integration to navigate back to specific locations, typically their homes, after lengthy and convoluted excursions.

Artificial intelligence in the mass production of natural enemies for biological control in modern agriculture

open access: yesPest Management Science, EarlyView.
Schematic overview of the graphical abstract illustrating an AI‐integrated framework for mass rearing, quality optimization, and precision release of NEs for sustainable pest management. The left section depicts Trichogramma and Chrysoperla being reared in automated chambers equipped with IoT‐enabled sensors for monitoring light, temperature, and ...

Flowering Plants Preferred by Bumblebees (Bombus Latr.) in the Botanical Garden of Medicinal Plants in Wrocław

open access: yesJournal of Apicultural Science, 2016
Due to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators.

Spontaneous Lorentz Violation, Nambu-Goldstone Modes, and Massive Modes

open access: yes, 2010
In any theory with spontaneous symmetry breaking, it is important to account for the massless Nambu-Goldstone and massive Higgs modes. In this short review, the fate of these modes is examined for the case of a bumblebee model, in which Lorentz symmetry ...
