Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

open access: yesInsect Science, Volume 33, Issue 4, Page 1719-1736, August 2026.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

Hidden Microbiota Inhabiting in Pollen Reserves of Honey Bee (Apis mellifera) From Amazonas Region Revealed by DNA Metabarcoding

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 4, August 2026.
DNA metabarcoding of honey bee pollen reserves from Amazonas region reveals that microbial communities are strongly shaped by their ecosystem. Despite high taxonomic turnover across different habitats, these microbiomes maintain stable, essential functions for pollinator health, though they remain highly vulnerable to habitat homogenization.

Genome-wide discovery and characterization of microsatellite markers from Melipona fasciculata (Hymenoptera: Apidae), cross-amplification and a snapshot assessment of the genetic diversity in two stingless bee populations

open access: yesEuropean Journal of Entomology, 2018
Brazilian native meliponines are currently threatened by increased human impacts. The assessment of their genetic variation by microsatellite DNA markers can assist in the conservation of populations and help in the planning and establishment of ...

Optimisation of Drop‐Sheet Sampling in Macadamia (Macadamia integrifolia) Orchards: An Optimised Method for Monitoring Insect Ecology

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Understanding orchard arthropod populations is a critical element of making strategic decisions regarding pest management. Therefore, it is paramount for farmers and crop consultants to use appropriate survey methods that provide a representative sample of orchard insect ecology. Currently, macadamia (Macadamia integrifolia) industry arthropod

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

open access: yesAustral 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 ...

Suction feeding in orchid bees (Apidae: Euglossini) [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Energy flux during nectar feeding is maximized at an intermediate sugar concentration, the value of which depends on the morphology of the feeding apparatus and the modality of fluid feeding. Biomechanical models predict that a shift from capillary-based lapping to suction feeding will lead to a decrease in this optimal sugar concentration.

Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 957-967, August 2026.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 822-830, August 2026.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...
