Characterization of the complete mitochondrial genome of Melanostoma scalare (Diptera: Syrphidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete mitochondrial genome of Melanostoma scalare was sequenced and reported here. The circle genome of the syrphid fly is 16,380 bp in length. There are 38 sequence elements including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a ...

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).

Detailed morphological descriptions of the immature stages of the ant parasite Microdon mutabilis (Diptera: Syrphidae: Microdontinae) and a discussion of its functional morphology, behaviour and host specificity

open access: yesEuropean Journal of Entomology, 2017
The myrmecophilous immature stages of hover flies of the genus Microdon Meigen, 1803 (Diptera, Syrphidae) are still poorly known and only about 15 species were previously incompletely described and/or illustrated using light microscopy based on ...

Syrphid aphidophagous predators in a food-web context

open access: yesEuropean Journal of Entomology, 2005
The main influences on the specificity of hoverfly larvae (Diptera: Syrphidae) to particular aphids are outlined. There are four main ones: aphid species, host plant, parasitoid impact and the presence of ants.

Sampling of flower-visiting insects: Poor correspondence between the catches of colour pan-trap and sweep netting

open access: yesEuropean Journal of Entomology, 2019
Pollinating insects are important and therefore, it is important to be able to assess and monitor changes in their abundance. Consequently, it is essential that the methods used to collect data have some level of precision and are accurate.

Description of the Puparium and Redescription of the Third-Instar Larva of Brachyopa panzeri (Diptera, Syrphidae) with New Data on its Biology

open access: yesZoodiversity, 2021
In this study, we report the rearing of Brachyopa panzeri from larva and elucidate its life circle with a duration of the pupal stage for the first time. We described the puparium of B. panzeri which morphology was unknown to the current study. The study

Patterns in diurnal co-occurrence in an assemblage of hoverflies (Diptera: Syrphidae)

open access: yesEuropean Journal of Entomology, 2013
In this study we analyzed the inter-specific relationships in assemblages of syrphids at a site in northern Italy in order to determine whether there are patterns in diurnal co-occurrence. We adopted a null model approach and calculated two co-occurrence
