Onion thrips, Thrips tabaci Lindeman, are an economic pest of alliums worldwide. In Ontario onion-growing regions, seasonal abundance and population trends of onion thrips are not well known. The objectives of this research were to investigate onion thrips population dynamics by using both white sticky traps and plant counts, to gain insight into flight height, and to determine the genus and se...

Processing and stabilising onion wastes (residues and surpluses of onion) could solve the environmental problem derived from a great onion wastes disposal. Moreover, obtaining stabilised onion by-products as natural antioxidant food ingredients could be advantageous to food industry, not only to improve the use of onion wastes but also to obtain new natural and functional ingredients. The aim o...

Management of onion maggot, Delia antiqua (Meigen), in onion requires the use of an insecticide applied at planting. Insecticide resistance and a dearth of available products have stimulated an effort to identify new insecticides for onion maggot control, especially chemistries that can be delivered as seed treatments. Onion seeds film-coated with fipronil, spinosad, clothianidin or thiamethoxa...

This study was performed to investigate the inhibitory effect of green onion produced in Korea on the growth of A. parasiticus, a toxigenic strain. The effect was studied using different concentrations of freeze-dried green onion in solid culture with potato-dextrose agar (PDA) or in liquid culture with yeast-extract sucrose (YES) broth at 25°C for 15 days. The addition of green onion to the me...

The effect of oral ingestion of different fractions of onion (Allium cepa)--extract, residue, and whole--at a dose level equivalent to intake of 50 g of onion per day for a 70-kg man, for 30 days, to male adult, normal, albino rats was studied on blood and erythrocyte membrane lipids and certain membrane-bound enzymes. Onion extract and residue showed hypercholesterolemic effect, while whole on...

Irradiated raw ground beef had lower a*- and b*-values than nonirradiated ones regardless of garlic or onion treatment at 0 d. Irradiation increased TBARS values of control ground beef, but addition of 0.5% onion or 0.1% garlic+0.5% onion reduced oxidative changes during storage. Addition of garlic or onion greatly increased the amounts of sulfur compounds, but the increase was greater with gar...

Onion Routing is an infrastructure for private communication over a public network. It provides anonymous connections that are strongly resistant to both eavesdropping and tra c analysis. Onion routing's anonymous connections are bidirectional and near realtime, and can be used anywhere a socket connection can be used. Any identifying information must be in the data stream carried over an anony...

457 Onion (Allium cepa L.) is an important export oriented vegetable among the cultivated allium in India. It is also known as “queen of kitchen”. Productivity of onion is affected by many biotic and abiotic stresses. For commercial cultivation of onion, both thrips and foliar diseases play the key role in reducing the bulb yield and quality of produce. Among the various foliar diseases affecti...
