Expanding the fly eye gene regulatory network: From Drosophila to the hoverfly Episyrphus balteatus.

PLoS Genetics
Comparing organ-specific gene regulatory networks (GRNs) across large evolutionary distances remains a major challenge, particularly when the species under study differ in data resolution.

Biology and feeding potential Episyrphus balteatus De Geer (Diptera: Syrphidae) on green apple aphid Aphis pomi De Geer (order Hemiptera: Aphididae) in Hills of Shimla, (H.P.), India

Environment Conservation Journal, 2020
In the  present study three species of syrphid predators were found feeding on green apple aphid on the apple nursery plants. These species are Betasyrphus serarius (Wiedemann), Episyrphus balteatus De Geer, and Metasyrphus confrater (Wiedemann).

Larval feeding capacity and pollination efficiency of the aphidophagous syrphids, Eupeodes frequens (Matsmura) and Episyrphus balteatus (De Geer) (Diptera: Syrphidae) on the cabbage aphid (Brevicoryne brassicae L.) (Homoptera: Aphididae) on mustard crop

Egyptian Journal of Biological Pest Control, 2020
The present investigation was carried out on in vitro mass multiplication, larval feeding capacity, and pollination efficiency of two aphidophagous syrphids viz., Eupeodes frequens (Matsmura) and Episyrphus balteatus (De Geer) (Diptera: Syrphidae) on ...

Landscape parameters explain the distribution and abundance of Episyrphus balteatus (Diptera: Syrphidae)

European Journal of Entomology, 2005
We studied the importance of forest structure (shape, edge length and orientation) and the crop mosaic (percentage of crops in the total land cover, within 100 and 2000 m from the forests) to the dynamics of an aphidophagous hoverfly Episyrphus balteatus.

Feeding Behavior and Host Plant Preferences of Episyrphus balteatus‎ (DeGeer) ‎ and Ischiodon scutellaris ‎(Fabricius) ‎ in Southern Punjab, Pakistan

Kufa Journal for Agricultural Sciences
During the present study, 300 adults along with 30 larvae of Episyrphus balteatus and 212 adults along with 25 larvae of Ischiodon scutellaris were collected from 15 and 13 host plants, respectively from Bahawalpur, Southern Punjab, Pakistan. The adults

Effect of temperature on biological characteristics and feeding capacity of Episyrphus balteatus (Diptera: Syrphidae) as important predator of the currant lettuce aphid, Nasonovia ribisnigri (Hemiptera: Aphididae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2020
Biological characteristics and feeding rate of Episyrphus balteatus on Nasonovia ribisnigri as an economically important pest of lettuce were evaluated at four constant temperatures (15, 20, 25 and 30 ± 1°C), 65 ± 5% RH and a photoperiod of 16L: 8D h ...

Chromosome-level genome assembly of marmalade hoverfly Episyrphus balteatus (Diptera: Syrphidae)

Scientific Data
Episyrphus balteatus can provide dual ecosystem services including pest control and pollination, which the larvae are excellent predators of aphid pest whereas adults are efficient pollinator.

Development of ovaries, allometry of reproductive traits and fecundity of Episyrphus balteatus (Diptera: Syrphidae)

European Journal of Entomology, 2000
Episyrphus balteatus only matures eggs after emergence. Ovaries develop in 4 stages. In the absence of oviposition sites, females refrain from ovipositing and their ovaries progressively fill the abdomen and then egg resorption occurs.

Intraguild interactions between the predatory hoverfly Episyrphus balteatus (Diptera: Syrphidae) and the Asian ladybird, Harmonia axyridis (Coleoptera: Coccinellidae): Effect of larval tracks

European Journal of Entomology, 2010
The effects of the larval tracks of Episyrphus balteatus DeGeer (Diptera: Syrphidae) and Harmonia axyridis Pallas (Coleoptera: Coccinellidae) on the egg laying behavior of females of the predatory hoverfly E.

Aphid honeydew: An arrestant and a contact kairomone for Episyrphus balteatus (Diptera: Syrphidae) larvae and adults

European Journal of Entomology, 2014
Predator searching efficiency increases in response to a variety of environmental cues associated with its prey. The sugary excretion of aphids (honeydew) has been found to act as a prey-associated cue for many aphid natural enemies. In the present study,
