Journal 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 ...

Shared pathogens among honey bees, wild bees and hoverflies in mountain ecosystems
Scientific ReportsThis study investigates the prevalence, abundance, and drivers of bee-associated pathogens in honeybees, wild bees, and hoverflies (Syrphidae) across four National Parks in Northern Italy, encompassing diverse altitudinal and habitat gradients.

Models of the potential distribution and habitat preferences of the genus Pipiza (Syrphidae: Diptera) on the Balkan peninsula [PDF]
Archives of Biological Sciences, 2013 Seven species of the genus Pipiza, collected throughout the southern and western Balkans, were used for the analysis of habitat preferences and potential geographical distribution on the Balkan Peninsula.

Insect Science, EarlyView.Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Insect 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.

Reductional activity of parasites on aphidophagous hoverflies [PDF]
, 2008 Parasites of aphidophagous hoverflies attack a great number of hoverflies species. During the three-year investigations of the aphidophagous species of Syrphidae family, 10 species of parasites were identified in the order of Hymenoptera, ecloded from ...

AgronomyThe occurrence of predatory Syrphidae (hoverflies) in green areas of cities and their role as biological control agents is determined in this work. During the study, 751 adults belonging to 21 species were captured in Moericke’s traps and with sweep nets,

The dual crisis: Climate change simultaneously drives pollinator decline and Pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Frontiers in Integrative Neuroscience, 2012 Hoverflies and blowflies have distinctly different flight styles. Yet, both species have been shown to structure their flight behaviour in a way that facilitates extraction of 3D information from the image flow on the retina (optic flow).

Sensory fusion in the hoverfly righting reflex
Scientific Reports, 2023 AbstractWe study how falling hoverflies use sensory cues to trigger appropriate roll righting behavior. Before being released in a free fall, flies were placed upside-down with their legs contacting the substrate. The prior leg proprioceptive information about their initial orientation sufficed for the flies to right themselves properly. However, flies
