THE PHENOLOGY OF OCCURRENCE OF DOMINANT PREDATORY SYRPHIDAE (DIPTERA) SPECIES IN APPLE ORCHARDS AND ON THEIR EDGES

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2017
The blooming wild plants in the vicinity of orchards may attract adult Syrphidae to these cultivations. Hence in 2008–2010 studies were conducted around Czempiń (western Wielkopolska) which covered the occurrence of the imagines of 5 dominant predatory ...

Testing molecular barcodes: Invariant mitochondrial DNA sequences vs the larval and adult morphology of West Palaearctic Pandasyopthalmus species (Diptera: Syrphidae: Paragini)

open access: yesEuropean Journal of Entomology, 2006
The intra- and interspecific variability in the West Palaearctic tibialis-group species of the subgenus Pandasyopthalmus (Diptera: Syrphidae: Paragus) was analysed.

Diptera Pests Occurring on Vegetable Crops in Poland

open access: yesJournal of Horticultural Research, 2023
In Poland, the share of Diptera in the species composition of the harmful entomofauna occurring on vegetable crops ranges from 20 to 25%. They occur on all vegetables grown in Poland (over 80 species and botanical varieties).

Phylogenetic relationships of the bacchine flower flies (Diptera: Syrphidae) based on molecular characters, with a description of a new species of Melanostoma (Schiner, 1860)

open access: yesContributions to Zoology, 2020
The phylogenetic relationships among the genera of the tribe Bacchini sensu lato (i.e., Syrphinae with simple, unsegmented aedeagus) were inferred using molecular evidence.

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks

open access: yesInsect Conservation and Diversity, EarlyView.
Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Seasonal polyphenism in Eristalis pertinax (Diptera: Syrphidae)

open access: yesEuropean Journal of Entomology, 2016
Eristalis pertinax varies seasonally, with the spring morph more hairy than the summer morph. We measured the size and the venation of the wings of the seasonal morphs.

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

open access: yesPhysiological Entomology, EarlyView.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]

open access: yes, 2020
There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

Dragon Fruit (Hylocereus undatus) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...
