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.

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

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).

Experiments with suction traps to assess the abundance of Syrphidae (Diptera), with special reference to aphidophagous species

open access: yes, 1959
Preliminary information on the abundance of some common species of Syrphidae was obtained from the catches in five suction traps, operated at Rothamsted during the summers of 1951, 1952 and 1953. Six of the eight ?abundant?

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

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

How do insects pollinate flowers? Behaviour during visitation determines high pollination efficiency by a generalist insect

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem services provide essential benefits to human survival and well‐being. Animal behaviour is central to the delivery of many ecosystem services, yet we know little about how behaviour drives services' provision.

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

open access: yesJournal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...
