Flower constancy in the hoverflies Episyrphus balteatus (Degeer) and Syrphus ribesii (L.) (Syrphidae)
The causes and consequences of flower constancy have been the focus of many studies, but almost all have examined the foraging behavior of bumblebees, honeybees, or butterflies. We test whether constancy occurs in an overlooked group of pollinators, the syrphid flies. Foraging sequences of wild flies of two species, Episyrphus balteatus and Syrphus ribesii, were examined when visiting flowers i...
متن کاملMitochondrial genomes of the hoverflies Episyrphus balteatus and Eupeodes corollae (Diptera: Syrphidae), with a phylogenetic analysis of Muscomorpha
The hoverflies Episyrphus balteatus and Eupeodes corollae (Diptera: Muscomorpha: Syrphidae) are important natural aphid predators. We obtained mitochondrial genome sequences from these two species using methods of PCR amplification and sequencing. The complete Episyrphus mitochondrial genome is 16,175 bp long while the incomplete one of Eupeodes is 15,326 bp long. All 37 typical mitochondrial g...
متن کاملAbundance of adult hoverflies (Diptera: Syrphidae) on different flowering plants
Encouraging natural enemies by growing attractive plants is considered an effective method of pest control in organic farming. However, it is important to identify which flowers best attract beneficial insects. In this study, relative attractiveness of 16 species of flowering plants to adult hoverflies was assessed by conducting timed observations of feeding-visit frequencies. The experiments w...
متن کاملOviposition behaviour and host colony size discrimination in Episyrphus balteatus (Diptera: Syrphidae).
Three bioassays were used to examine the oviposition behaviour of the hoverfly, Episyrphus balteatus (Degeer) in which various stimuli purported to influence host assessment and choice were tested. Episyrphus balteatus failed to exhibit enhanced behavioural responses, in terms of approaches and landings, to artificial leaves with the highest numbers of aphids, suggesting that females are merely...
متن کاملBehavioural evidence for a visual and proprioceptive control of head roll in hoverflies (Episyrphus balteatus).
The ability of hoverflies to control their head orientation with respect to their body contributes importantly to their agility and their autonomous navigation abilities. Many tasks performed by this insect during flight, especially while hovering, involve a head stabilization reflex. This reflex, which is mediated by multisensory channels, prevents the visual processing from being disturbed by...
