Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Multi‐angle, cross‐domain fusion strategy enhances automated insect identification and hierarchical categorization: a case study on assassin bugs (Hemiptera: Reduviidae)

open access: yesCladistics, EarlyView.
Abstract Automated insect identification systems hold significant value for biodiversity monitoring, pest management, citizen science initiatives and systematic studies, particularly in an era of declining expertise in insect taxonomy. However, current deep learning approaches often rely on standardized specimen photos from limited‐angles and ...

Stingless Bees of Costa Rica

open access: yes, 2012
The keeping of stingless bees (Apidae, Meliponini) or meliponiculture is carried out in a rustic and traditional way in Costa Rica. This is an activity present in several regions of the country, especially among the inhabitants of rural areas, mostly on the Pacific coast rather than the Atlantic region.

A Comparative Characterization of Physicochemical and Antioxidants Properties of Processed Heterotrigona itama Honey from Different Origins and Classification by Chemometrics Analysis

open access: yesMolecules, 2019
Stingless bee honey produced by Heterotrigona itama from different botanical origins was characterised and discriminated. Three types of stingless bee honey collected from acacia, gelam, and starfruit nectars were analyzed and compared with Apis ...

No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

open access: yesEcological Entomology, EarlyView.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

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

Intergenerational reproductive parasitism in a stingless bee [PDF]

open access: yesMolecular Ecology, 2009
Insect colonies have been traditionally regarded as closed societies comprised of completely sterile workers ruled over by a single once-mated queen. However, over the past 15 years, microsatellite studies of parentage have revealed that this perception is far from the truth (Beekman & Oldroyd 2008). First, we learned that honey bee queens are far more

Hermetia illucens and Hermetia fenestrata (Diptera: Stratiomyidae) Colonization of “Spoiled” Stingless Bee Geniotrigona thoracica (Hymenoptera: Apidae) Hives in Malaysia

open access: yesInsects, 2020
Meliponiculture, the keeping of domesticated stingless bees such as Geniotrigona thoracica (Smith, 1857) (Hymenoptera: Apidae), is an increasingly popular agricultural industry in Malaysia.

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

Bees at War: Interspecific Battles and Nest Usurpation in Stingless Bees [PDF]

open access: yesThe American Naturalist, 2014
We provide the first evidence for interspecific warfare in bees, a spectacular natural phenomenon that involves a series of aerial battles and leads to thousands of fatalities from both attacking and defending colonies. Molecular analysis of fights at a hive of the Australian stingless bee Tetragonula carbonaria revealed that the attack was launched by
