Cypripedium subtropicum (Orchidaceae) employs aphid colony mimicry to attract hoverfly (Syrphidae) pollinators.

open access: yesNew Phytologist, 2020
In Orchidaceae, pollination is mostly animal-mediated, and one-third of species have evolved a deceptive pollination mechanism without rewards. Cypripedium is a representative lineage of non-rewarding orchids restricted to temperate regions.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Life cycle and growth pattern of the endangered myrmecophilous Microdon myrmicae (Diptera: Syrphidae)

open access: yesEuropean Journal of Entomology, 2012
In Europe there are only a few species of the syrphid fly Microdon, which live in the nests of various genera of ants. For most of these rare flies, details of their biology, larval behaviour and relationships with their hosts are still not yet well ...

Design, Training, and Field Validation of a YOLOv8‐Based Automated Trap for Remote Detection of Codling Moth, Cydia pomonella

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We developed and field‐validated a fully automated trap for Cydia pomonella monitoring, combining a camera with a YOLOv8 object‐detection model for remote insect identification. In controlled laboratory validation, the model showed strong performance (precision 0.77, recall 0.83), with moderate reductions under field conditions. Across six experiments,

Arthropod diversity in peas with normal or reduced waxy bloom [PDF]

open access: yes, 2004
Crop traits can alter economically important interactions between plants, pests, and biological control agents. For example, a reduced waxy bloom on the surface of pea plants alters interactions between pea aphids and their natural enemies. In this study,

The complete mitochondrial genome of Melanostoma orientale (Diptera: Syrphidae)

open access: yesMitochondrial DNA Part B: Resources, 2020
The mitochondrial genome of Melanostoma orientale has been decoded by Illumina sequencing. The mitogenomic size is 16,229 bp with 40.96% A, 40.29% T, 10.60% C, and 8.15% G. It is encoded with 13 protein-coding genes, 2 ribosomal RNA, and 22 transfer RNAs.

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...

THE OCCURRENCE FREQUENCY OF Syrphidae (Diptera) SPECIES IN APPLE ORCHARDS AND ON THEIR EDGES

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2013
The study was aimed at determining the attractiveness of neighbouring habitats for Syrphidae (Diptera). The frequency of Syrphidae occurrence in apple orchards and on their edges was studied in 2008–2010.

DNA Barcoding to Improve the Taxonomy of the Afrotropical Hoverflies (Insecta: Diptera: Syrphidae) [PDF]

open access: yes, 2016
The identification of Afrotropical hoverflies is very difficult because of limited recent taxonomic revisions and the lack of comprehensive identification keys.

Forest type influence on Heliconia‐dipteran interaction networks

open access: yesInsect Conservation and Diversity, EarlyView.
Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.
