Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

open access: yes, 2013
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

open access: yesEcological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Diverse Diets with Consistent Core Microbiome in Wild Bee Pollen Provisions

open access: yesInsects, 2020
Bees collect pollen from flowers for their offspring, and by doing so contribute critical pollination services for our crops and ecosystems. Unlike many managed bee species, wild bees are thought to obtain much of their microbiome from the environment ...

Roadside pollinator populations and the negative impact of intensive roadside vegetation maintenance

open access: yesInsect Conservation and Diversity, EarlyView.
Less intensively managed roadsides had higher numbers of flower flies and bees; bee diversity was also higher in those roadsides. Community composition was similar across both management types, indicating that roadsides support a fairly homogeneous pollinator community, regardless of management.

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

The impact of geography and climate on the population structure and local adaptation in a wild bee

open access: yesEvolutionary Applications, 2023
Deciphering processes that contribute to genetic differentiation and divergent selection of natural populations is useful for evaluating the adaptive potential and resilience of organisms faced with various anthropogenic stressors.
