A new record of flower flies (Diptera: Syrphidae) for the fauna of Iran [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2018
During the study of flower flies (Diptera: Syrphidae) associated with colza (Brassica napus) fields in Sari (Mazandaran Province, Iran) in 2015–2016, a total of six species i.e.

Surrounding Semi-Natural Vegetation as a Source of Aphidophagous Syrphids (Diptera, Syrphidae) for Aphid Control in Apple Orchards

open access: yesAgriculture, 2023
The influence of different semi-natural surroundings adjacent to apple orchards on the occurrence of predatory syrphids and biological control of Aphis pomi Deg. and Dysaphis plantaginea Pass. was compared.

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

open access: yesPest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

The predators of aphids on apples in the region East Sarajevo (Bosnia and Herzegovina)

open access: yesPlant Protection Science
Predators of aphids on apples were studied during the growing season in 2021 and 2022 in the region of East Sarajevo, Bosnia and Herzegovina. Eleven predator species were found on eight apple cultivars in the colonies of three aphid species, Aphis spp ...

Odorant Binding Proteins and Chemosensory Proteins in Episyrphus balteatus (Diptera: Syrphidae): Molecular Cloning, Expression Profiling, and Gene Evolution

open access: yesJournal of Insect Science, 2020
Aphidophagous syrphids (Diptera: Syrphidae) are important insects in agroecosystems for pollination and biological control. Insect chemoreception is essential for these processes and for insect survival and reproduction; however, molecular determinants ...

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological 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.

Non‐crop habitats and cover crops as potential ecological corridors and stepping stones for autumnal migrating hoverflies

open access: yesInsect Conservation and Diversity, EarlyView.
Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.
