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

The 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

The diversity of honey bee and entrance characteristics of stingless bees nests at a meliponiculture in Batu Gadang, West Sumatra [PDF]

BIO Web of Conferences
Honey bees, consist of true honey bee bees and stingless bees, are common in Indonesia. This study aimed to do the inventory on honey bee species as well as to study the entrance characteristics of stingless bee nests that exist at the meliponiculture in

Diversity of Mites Associated With Stingless Bees (Hymenoptera: Meliponini) in Forest Fragments in Brazil: Empirical Validation of an Efficient and Low‐Cost Sampling Method

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Despite the importance of understanding mite–bee interactions, standardized and noninvasive methods for sampling mite communities in stingless bee hives remain limited. This study aimed to evaluate a novel, low‐cost sampling technique using a custom‐built suction device, the Portable Mite Aspirator (PMA), for collecting mites from hives of ...

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

Cladistics, Volume 42, Issue 4, Page 358-373, August 2026.
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 ...

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

Ecological Entomology, Volume 51, Issue 4, Page 799-809, August 2026.
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

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2577-2607, August 2026.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Detection of Honey Adulteration Using Thermorheological and Spectroscopic Analyses: Independent Evaluation With Linear Latent‐Variable and Gradient Boosting Models

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT Honey adulteration is a prevalent economic fraud that demands robust and reliable detection methods. In this study, a proof‐of‐concept was developed on a comparative study of oscillatory thermorheology (20°C–80°C) and spectroscopic techniques, including UV‐Vis and fluorescence spectroscopy, for the detection of adulteration with glucose ...

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
