Plant-Pollinator Interactions in Grasslands Established on Arable Land. [PDF]

Ecol Evol
We compared plant‐pollinator networks in newly established and old, permanent grasslands in a Central European agricultural landscape. Newly established grasslands showed higher pollinator visitation frequency and diversity per plant species, especially for solitary bees and syrphids, with a comparable network structure to old grasslands.

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).

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 ...

Dominated Spider Species and the Predation Assessment on <i>Apolygus lucorum</i> (Hemiptera: Miridae) in a Tea Plantation. [PDF]

Ecol Evol
The mirid bug Apolygus lucorum (Meyer‐Dür) is a major pest affecting tea. Identifying the dominant predatory spiders of the mirid bug can provide a scientific basis for developing biological control technologies. Xysticus ephippiatus demonstrates the greatest potential as a biological control agent against A. lucorum.
