The aphid Amphorophora agathonica Hottes (Hemiptera: Aphididae) is an important virus vector in red (Rubus idaeus L.) and black (Rubus occidentalis L.) raspberries in North America. Raspberry resistance to A. agathonica in the form of a single dominant gene named Ag1 has been relied upon to help control aphid-transmitted plant viruses; however, the mechanism of resistance to the insect is poorl...

Three species of aphids attack pecan foliage, Carya illinoensis (Wang.) K. Koch, and cause economic damage. We tested a kaolin-based particle film against one of these aphid species, black pecan aphid, Melanocallis caryaefoliae (Davis). Effect of particle film on host selection, adult mortality, and production of nymphs by M. caryaefoliae was tested on seedling pecans in the laboratory. Fewer M...

The social and economic burden caused by chronic diseases such as obesity, diabetes, heart disease, and cancer is enormous. To reduce the impact of these diseases, we must find ways to reduce their prevalence. Epidemiological studies have found links between the incidence of cancer and consumption of dry edible bean {Phaseolus vulgaris L.) in the human diet. Correa (1981) examined data from 41 ...

BACKGROUND Legumes are a rich source of proteins but are also potential elicitors of IgE-mediated food allergy. This study aimed to isolate and characterize a major allergen of Phaseolus vulgaris (kidney bean) and determine its allergenicity. METHODOLOGY Kidney bean allergen was purified using Q Sepharose column (anion exchanger) and eluates with high intensity were pooled to purify protein u...

This study evaluated whether grass intercropping can be used to alleviate Fe deficiency chlorosis in dry beans (Phaseolus vulgaris L.) grown in high pH, calcareous soils with low organic matter. Field studies were conducted at the University of Wyoming Sustainable Agriculture Research and Extension Center in 2009 and 2010. Black- and navy beans were grown alone or intercropped with annual ryegr...

yellow, and even drop. Other symptoms of direct feeding damage include plant stunting, poor pod fill, reduced Since 2000, the soybean aphid (Aphis glycines Matsumura) has pod and seed counts, smaller seed size, and nutrient become a major pest of soybean [Glycine max (L.) Merr.] in North America. In the USA, there are currently no commercial soybean deficiencies resulting in overall yield and q...

The flower fly species, Eupeodes nuba (Wiedemann, 1830) (Diptera: Syrphidae) is crucial for agroecosystems as it provides various ecosystem services such pest control through the use of predatory larvae and crop pollination by adults. In this research, consumption rate different instars Aphis fabae (Scopoli, 1763) E. has been studied under laboratory conditions at 25±2 °C, 60±10% humidity (RH)....

introduction: lysiphlebus fabarum marshall (hymenoptera: braconidae: aphidiinae) is a common aphidiine parasitoid in central europe, where it attacks more than 70 species of aphids. although both unisexual (thelytokous) and bisexual (arrhenotokous) strains of l. fabarum have been reported in iran, the former appear to be more widely distributed. aphid control in iran relies heavily on pesticide...

Legumes, such as black beans (Phaseolus vulgaris L.) and chickpeas (Cicer arietinum L.), have a low glycemic index, and may reduce the glycemic load of meals in which they are included. Although the low glycemic response of beans consumed alone has been documented, few studies have examined the glycemic response to traditional food combinations such as black beans and rice or chickpeas and rice...
