Determination of economic injury level of Sitobion avenae (Hom.: Aphididae) on wheat of Chameran variety in Ahwaz [PDF]

نامه انجمن حشره‌شناسی ایران, 2015
The drought phenomenon in recent years has increased the oat aphid (Sitobion avenae Fab.) population in khuzestan wheat fields. Considering the existence of different natural enemies of this pest in cereal fields, the best control method would be based ...

Comparison and validation of population models for cereal aphids

, 2009
Models used to simulate changes in populations of cereal aphids need to be compared and validated if they are ever to be improved sufficiently for wide-scale use in crop protection.

Phytochemical Profile and Insecticidal Potential of Two Halophytes, Atriplex halimus and Suaeda fruticosa, Against Tribolium confusum: In Vitro and In Silico Approaches

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Exploring the insecticidal activity of two Algerian halophytes, Atriplex halimus and Suaeda fruticosa. ABSTRACT This study aimed to investigate the phytochemical profile and evaluate the in vitro and in silico insecticidal activities of methanolic extracts from two halophytes, Atriplex halimus (A. halimus) and Suaeda fruticosa (S. fruticosa).

Planting date and seeding rate effect on winter malting barley grain yield and quality in northwest Ohio

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract With the growth in the craft brewing industry, farmers are interested in producing winter malting barley (Hordeum vulgare L.). Timely barley planting is important; however, wet weather often results in delays. The objective of this experiment was to identify the agronomic optimum seeding rate (the seeding rate at which yield is maximized) for ...

Association mapping for hop cone chemistry and morphology identifies natural beneficial allele stacks

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Efforts are underway to increase the efficiency and precision of selection hop (Humulus lupulus L.) breeding using genomics. Little is known, however, about the genetic control of important traits like α‐and β‐acids contents, oil content, and cone morphological characteristics, all of which play an important role in determining the utility and

Strip cropping in practice: Higher slug abundance despite a higher number of slug‐predating carabid species

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
To avoid increased slug damage in strip cropping fields in slug‐prone areas, potential slug‐source crops should be spatially separated from slug‐sensitive crops. However, an increase in slug abundance should not deter the adoption of strip cropping as higher slug damage in strip cropping systems was rarely observed by farmers.

The effect of barley yellow dwarf virus on honeydew production by the cereal aphids Sitobion avenae and Metopolophium dirhodum

, 1982
Individual S. avenae and M. dirhodum excreted significantly fewer droplets of honeydew on plants infected with BYDV than on healthy plants. S. avenae excreted less honeydew on the ears than on the leaves of wheat. M. dirhodum excreted less than S. avenae

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, Volume 33, Issue 3, Page 1109-1122, June 2026.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad‐Spectrum Antiviral Resistance in Crops

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3821-3839, June 2026.
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...

Three Decades of China's Bt Cotton: Achievements and Insights

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4393-4414, June 2026.
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.
