Abstract:
... Among insects, female oviposition preferences are critical to understanding the evolutionary dynamics between herbivores and hosts. Previous studies have shown than in Drosophila, resource use has a strong genetic basis, although there is evidence that preferences are adaptable given isolation from ancestral hosts. Given the high degree of adaptability and behavioral plasticity of invasive species ...

Abstract:
... AbstractRubus dianchuanensis, a new name for the species previously named as R. vicarius by W. O. Focke in 1911, is proposed. A detailed description, illustrations, and remarks on its phenology, ecology, and geographic distribution are provided. This raspberry (subg. Idaeobatus) is endemic to China and was only found in Sichuan and Yunnan, southwest China. Morphologically, it is most similar to R ...

Abstract:
... Garbage classification technology is not only an important basis for the harmless treatment of waste and resource recovery, but also the inevitable trend of social development. The current garbage classification methods rely on manual classification in the garbage collection stage, and it is difficult to achieve satisfying results in consistency, stability, and sanitary conditions. For this reason ...

Abstract:
... In Central Russia, the area of possible effective use of raspberry varieties and their productivity and production values are determined by the plant tolerance to a complex of adverse environmental factors. In this regard, the introduction of new varieties and hybrids should be accompanied by analyzing not only their productivity, but also their winter hardiness and drought resistance. In this pap ...

Abstract:
... The PV-assisted charging station (PVCS) aggregates the two key resources of electric vehicle (EV) charging load and photovoltaic (PV) system to maximize operation profit. In order to quantify the PVCS impact to grid and the renewable energy utilization by EV charging load, it is crucial to predict the PVCS net power and capture the most correlated factors for power variation. Given that the PVCS i ...

Abstract:
... This article describes the preparation of hierarchical microsieves via float-casting using raspberry particles. The raspberry particles consist of a larger spherical particle (the core) and smaller particles (satellites) that are attached on the surface of the core and were connected to the core via a surface reaction of isocyanate and amino groups. The raspberry particles were spread onto a water ...

Abstract:
... The nutritional and commercial value of double yolk eggs is higher than that of single yolk eggs, but the traditional manual identification of double yolk eggs is costly, inefficient and has high error. For rapid and accurate identification of double yolk eggs, a portable double yolk nondestructive identification system and an online double yolk nondestructive identification system are proposed in ...

Abstract:
... This study aimed to verify if microwave hydrodiffusion and gravity (MHG) could efficiently extract anthocyanins from strawberries and raspberries with low environmental impact and costs. Our findings revealed that it was possible to extract 69 and 64% anthocyanins from the strawberries and raspberries in a single extraction step, respectively. When the co-product (product remaining after extractin ...

Abstract:
... Traditional manual visual grading of fruits has been one of the important challenges faced by the agricultural industry due to its laborious nature as well as inconsistency in inspection and classification process. Automated defects detection using computer vision and machine learning has become a promising area of research with a high and direct impact on the domain of visual inspection. In this ...

Abstract:
... A series of alkylpyrazines, contributing to the overall flavor, are described in tea and tea infusions. Their low concentrations and moderate water solubility are facing analytical trouble when it comes to typical applied headspace analyses. Accordingly, a stir bar sorptive extraction methodology (SBSE) was established. It was found that immersion-based techniques (direct-immersion SBSE (DI-SBSE) ...

Abstract:
... The development of new catalyst materials for energy-efficient chemical synthesis is critical as over 80% of industrial processes rely on catalysts, with many of the most energy-intensive processes specifically using heterogeneous catalysis. Catalytic performance is a complex interplay of phenomena involving temperature, pressure, gas composition, surface composition, and structure over multiple l ...
... Here is examined the colour development from common anthocyanins (i.e., cyanidin, delphinidin, malvidin, and pelargonidin glycosides) and from anthocyanins-rich extracts (i.e., bilberries, strawberries, and raspberries), using zinc-anthocyanin complexes as molecular probe. We have observed the absorbance increase in the blue region in presence of large excess of zinc ion at acidic pH for cyanidin ...
... The eucoiline species Ganaspis brasiliensis (von Ihering) (Hymenoptera: Figitidae) is recorded for the first time in Argentina, with confirmation of parasitism of Drosophila suzukii (Matsumura) infesting healthy raspberry fruit (Rubus idaeus L. cv. “Heritage”) still on the plant. Drosophila suzukii puparia were recovered from fruit collected in an organic farm in Tafí del Valle, Tucumán, Argentina ...

Abstract:
... In Sterile Insect Technique (SIT) programs, the released sterile insects must attain sexual maturity at an early adult age so that a large proportion survive to mature and contribute to reducing reproduction of pest populations. Previous field studies based on release of adult Queensland fruit fly, Bactrocera tryoni (Froggatt) (‘Q‐fly’), at 2 days of age found a significant increase in the recaptu ...
