Abstract:

Experiments on the preying capability of different stages of larvae of coccinellid and syrphid flies on the mustard aphid, Lipaphis erysimi (Kalt.), were conducted in a laboratory during the winter cropping seasons of 2009&ndash;2010 and 2010&ndash;2011. Results revealed that grubs of the Coccinella septempunctata Linn. preyed the highest number of mustard aphids (average 61.42 aphids/day) followed by Syrphus confrater Wied (34.81 aphids/day), Syrphus balteatus Deg. (32.26 aphids/day) and Ischiodon scutellaris Fab. (27.76 aphids/day) during their larval span. Among the larval stages of

AbstractThe balsam twig aphid, Mindarus abietinus Koch (Hemiptera: Aphididae), is one of the most important pests of balsam fir (Abies balsamea (Linnaeus) Miller; Pinaceae) grown as Christmas trees in eastern North America. Aphid feeding on the current-year shoots results in needle distortion and shoots stunting, which reduces the aesthetic value of balsam fir trees and can have substantial economic impact. Syrphidae (Diptera) fly predators attacking this aphid are poorly known. We identified four species attacking the balsam twig aphid. Syrphus torvus Osten Sacken (Diptera: Syrphidae) was the

The occurrence of predatory Syrphidae (hoverflies) in green areas of cities and their role as biological control agents is determined in this work.

In both cases, the dominants were Episyrphus balteatus (Deg.) Sphaerophoria scripta (L.), and Syrphus vitripennis Meig. (L.)

An intriguing ecological interaction can exist between aphids and Syrphid flies, particularly in the setting of millet crops. Aphids (Order Hemiptera: Family Aphididae) are a problem variety of crops, including all types of millets. Syrphid flies (Order Diptera: Family Syrphidae) naturally prey on aphids when they are in their larval stage. Syrphid fly larvae are referred to as "aphid lions" or "hoverfly larvae." Aphids are the main source of food for these larvae, and they manage the aphid population in millet crops. Therefore, Syrphids are used as natural enemies and biological control agent

Abstract:

Fibre ropes offer beneficial properties for mooring of floating offshore wind turbines (FOWTs). However, the mooring line’s stiffness is both load-history and load-rate dependent. A quasi-static stiffness is observed for slow loading, with a higher stiffness related to rapid, cyclic loading (dynamic stiffness). Design standards provide different guidelines for how to combine these in the mooring analysis. This paper describes procedures for adapting laboratory test stiffness results to the Syrope and a bi-linear model and investigates the consequence of using the models for load calculations.

The results shows revealed that Apis mellifera (5.96) was the most abundant visitor and highly significant over A. florea (4.46), syrphid fly (2.97), A.dorsata (2.62) and A.cerana (1.66) visitor. Irrespective of species, abundance of bees was the lowest at 0700-0900 h (0.73 bees/m2/5 minutes) and the highest at 1100-1300 h (6.29 bees/m2/5 minutes)

Abstract:

Land abandonment is a multifaceted, nonlinear, worldwide phenomenon that is influenced by a variety of factors and opinions. The goal of this study was to understand the significance of land abandonment for true bugs and syrphids in three grassland management regimes that includes abandoned, intensive, and extensive alpine organic grasslands. In 2021 and 2022, we sampled true bugs and syrphids by applying observation plot and sweep netting sampling methods. Extensive grasslands had significantly higher true bug and syrphid abundance compared to abandoned grasslands. However, no difference of s

Abstract:

Hyper-arid regions are characterized by extreme conditions for growing and lack of water (<100 mm annual rainfall average), where desertification renders human activities almost impossible. In addition to the use of irrigation, different viticultural strategies should be taken into account to face the adverse effects of these conditions in which rootstocks may play a crucial role. The research aim was to evaluate the effects of the rootstock on yield, vigor, and petiole nutrient content in Syrah grapevines growing under hyper-arid conditions during five seasons and compare them to ungrafted

Abstract:

The escape responses exhibited by pea aphids were examined at three different temperatures, 15, 20, and 25 °C, using two different predators: syrphid larvae and coccinellid beetles. Coccinellid beetles foraged more vigorously at higher temperatures resulting in greater vibrations on the host plant as they searched for aphids. Foraging rates for syrphids were slower by comparison and did not vary with temperature. We found that most aphids dropped off the host plant when confronted by coccinellid beetles, especially at higher temperatures, and backed up when confronted by syrphid larvae regardl

Abstract:

This paper presents the integration of a Monte-Carlo solver inside SYRTHES, an open-source thermal code, originally based on finite elements method. Insensitive to both the geometric complexity of the model and the fineness of its discretization, this stochastic method is a good complementary option to simulate large configurations with specific locations of interest. Radiation, conduction and convection can be combined to solve thermal problems in complex geometries. The Monte-Carlo method is described before showing its integration in the code SYRTHES.

Grapevine (Vitis vinifera L.) expresses different responses to water stress, depending not only on genotype, but also on the influence of vineyard growing conditions or seasonality. Our aim was to analyse the effects on drought response of two grapevine cultivars growing on two soils, one water draining (WD) containing sand 80% volume and the other water retaining (WR), with no sand. Under these two different water-holding capacities Syrah, displaying a near-anisohydric response to water stress, and Cabernet Sauvignon (on the contrary, near-isohydric) were submitted to water stress in a pot tr

Changes in the principal phenolic compounds during the maceration-fermentation process of Garnacha, Merlot and Syrah grapes cultivated in Aragón region (northeast of Spain) have been investigated. While Garnacha is a traditional grape variety cultivated in this region, Merlot and Syrah have been introduced recently. During fermentation, Syrah showed the highest concentration in anthocyanins, flavan-3-ols and flavonols (802.7 ± 0.5 mg/L, 74.7 ± 2.4 mg/L and 37.1 ± 1.5 mg/L at the end of fermentation, respectively).

Abstract This article presents a full edition, with translation and detailed commentary, of SyrHT 1 and SyrHT 388, the only two Syriac medical fragments found in Turfan. Based on a re-examination of the original text, this article shows that the Turfan fragments have parallels in Galen’s De compositione medicamentorum secundum locos and contain elements of Hippocratic recipes as well. This adds further evidence that Syriac Christians had brought Hellenistic medical lore to Turfan at an early date.
