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

Ecological 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

Comparative toxicity of fipronil, malathion, and thiamethoxam on the stingless bee Tetragonisca fiebrigi (Schwarz, 1938)

Acta Scientiarum: Biological Sciences, 2022
Stingless bees are important pollinators for various plant crops. We investigated the susceptibility of Tetragonisca fiebrigi to sublethal concentrations of insecticides fipronil, malathion, and thiamethoxam (administered through contact and ingestion ...

Stingless bee nesting biology [PDF]

Apidologie, 2006
Par rapport au genre Apis, les abeilles sans aiguillon (Hymenoptera, Apidae, Meliponini) sont des sources variees et uniques de miel, avec 50 fois plus d'especes et une origine qui remonte au Cretace. Les reines s'accouplent une fois, les ouvrieres n'ont pas d'aiguillon, les mâles butinent, la cire n'est pas le materiau primaire pour la construction et

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

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

Journal 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).

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

No evidence for missed mutualists in an invasive plant with the buzz pollination syndrome

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The missed mutualist hypothesis predicts that the absence of mutualistic partners poses a barrier to introduced species becoming invasive. Yet, some alien plants thrive despite potential dependence on certain pollinators. For example, buzz‐pollinated plants typically have specialist floral morphologies and benefit from buzz pollinator behavior

A scientific note on the use of stingless bees for commercial pollination in enclosures [PDF]

, 1999
Stingless bees are considered to be very important pollinators in the tropics, and they are known to effectively pollinate at least 9 crops [1]. Nevertheless, they are seldomly used for commercial pollination.

Stingless Bees of Costa Rica

, 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.
