Do crab spiders perceive Batesian mimicry in hoverflies? [PDF]
, 2016 Many putative Batesian mimics only approximately resemble their supposed models, and such “imperfect” mimics are readily distinguished from defended species by humans and other vertebrates.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)
Insect Science, EarlyView.As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

The fauna of hoverflies (Diptera: Syrphidae) of Vojvodina province, Serbia [PDF]
, 2009 Many hoverfly species of faunal and zoogeographical interest are found in Serbia's northern province of Vojvodina due to the diversity of its biotopes.

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.

Evidence for Batesian mimicry in a polymorphic hoverfly [PDF]
, 2014 Palatable Batesian mimics are avoided by predators because they resemble noxious or defended species. The striking resemblance of many hoverflies to noxious Hymenoptera is a “textbook” example of Batesian mimicry, but evidence that selection by predators

Contrast sensitivity of insect motion detectors to natural images [PDF]
, 2008 How do animals regulate self-movement despite large variation in the luminance contrast of the environment? Insects are capable of regulating flight speed based on the velocity of image motion, but the mechanisms for this are unclear.

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.

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,

Pollinator attractiveness of five weeds [PDF]
, 2018 The number of pollinators in agro-ecosystems world wide has declined alarminglyin recent decades due to poora gricultural practices such as the intensive use of pesticides and monocultures.Postprint (published ...

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
