The cephalic labial gland secretions of two socially parasitic bumblebees Bombus hyperboreus (Alpinobombus) and Bombus inexspectatus (Thoracobombus) question their inquiline strategy
Social parasitic Hymenopterans have evolved morphological, chemical, and behavioral adaptations to overcome the sophisticated recognition and defense systems of their social host to invade host nests and exploit their ...
Yield and Cost Effects of Plot-Level Wheat Seed Rates and Seed Recycling Practices in the East Gojam Zone, Amhara Region, Ethiopia: Application of the Dose–Response Model
Previous studies investigated the effects of seed rates and seed recycling practices on the yield and yield-related variables. However, higher yield does not always guarantee cost-efficiency. This study aimed to investigate ...
Distribution of discretely scored descriptors in a pure line faba bean (Vicia faba L.) germplasm collection
Because of the partially insect cross-pollinated nature of faba bean (Vicia faba L.), ICARDA maintains two types of faba bean germplasm collections. The ILB (International Legume Faba Bean) collection consists of the ...

مقاومة العائل، الممارسات الزراعية والمكافحة الحيوية مكونات أساسية في برامج المكافحة المتكاملة للآفات; Host Plant Resistance, Cultural Practices, and Biological Control: Essential Components in IPM Programs
A number of pathogens persist in plant remains, and reproduce on them sexually, as they may persevere
on infected seeds, and these become sources of disease transmission from one field to another and from one field to ...
Amplified fragment length polymorphism among Rhynchosporium secalis isolates collected from a single barley field in Syria
AFLP markers were used to measure the amount and distribution of genetic variation among Rhynchosporium secalis isolates on a microgeographical scale in Syria. Forty isolates hierarchically sampled from a single barley ...

Relationships of grain delta C-13 and delta O-18 with wheat phenology and yield under water-limited conditions
Stable carbon isotope composition (delta C-13) of dry matter has been widely investigated as a selection tool in cereal breeding programmes. However, reports on the possibilities of using stable oxygen isotope composition ...

prácticas agrícolas más productivas y menos riesgosas en las zonas de ladera de las
montañas andinas, gracias a la conversión de terrenos ...
Variation in reproductive capacity and virulence on different genotypes and resistance genes of Triticeae, in the cereal cyst nematode species complex
Two sets of experiments in 1998 and 1999 studied the (a)virulence status of 14 populations of Heterodera avenae, and two populations each of H. filipjevi and H. latipons towards the resistance genes and genotypes of ...
