Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a well-known onion pest worldwide. Onion thrips cause both direct and indirect damage to onion by feeding and ovipositing on leaves that may cause green onions (scallions) to be unmarketable and dry bulb onion size to be reduced. Onion thrips can also transmit several plant pathogens that reduce onion bulb size and quality. One ...

BACKGROUND Cerebrotendinous xanthomatosis (CTX) is a rare lipid-storage disease. We investigated the clinic manifestation, histopathology and sterol 27-hydroxylase gene (CYP27A1) in a Chinese family with Cerebrotendinous Xanthomatosis (CTX). CASE PRESENTATION A 36-year-old female with typical CTX clinical manifestation had Spindle-shaped lipid crystal clefts in xanthomas and "onion-like demye...

A simple, fast and inexpensive analytical method was developed and validated for screening of Fluroxypyr-Meptyl, a selective post-emergent systemic broadleaf herbicide in onion (plant leaf, bulb) and soil using GC-MS/MS. The method comprised of extraction with ethyl acetate using matrix solid phase dispersion method followed by column chromatographic and dispersive solid phase extraction cleanu...

A Cook’s tour is presented of the organosulfur chemistry of the genus Allium, as represented, inter alia, by garlic (Allium sativum L.) and onion (Allium cepa L.). We report on the biosynthesis of the S-alk(en)yl-L-cysteine S-oxides (aroma and flavor precursors) in intact plants and on how upon cutting or crushing the plants these precursors are cleaved by allinase enzymes, giving sulfenic acid...

In New York, onion [ Allium cepa L. (Alliaceae)] fields often border woods or other vegetable fields. Because onion maggot adults, Delia antiqua (Meigen) (Diptera: Anthomyiidae), spend a significant portion of their time outside of onion fields, surrounding habitat may affect patterns of fly activity and oviposition within onion fields. To better understand these patterns throughout the onion-g...

The study investigated the effect of 10% aqueous extracts ginger, garlic and onion on quality shelf life frozen chevon pork as reflected by changes in values 2-thiobartituric acid reactive substances (2-TBARS) total volatile basic nitrogen (TVB-N) over a 14 day storage under conditions.  pH, 2-TBARS TVB-N were measured from at -20°C after days. resulted low pH 5.63, 5.79 5.67 for mixed...

Onion thrips, Thrips tabaci Lindeman, colonization of onion fields may be influenced by bordering crop and non-crop habitats. Identifying habitats adjacent to onion fields associated with high T. tabaci infestations would be valuable for improving scouting efforts and management decisions. A 3-year study examined adult T. tabaci colonization patterns within onion fields early (June through earl...

Identifying locations where onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), overwinter and subsequently disperse is important for designing control strategies. In upstate New York from 2003 through 2006, potential overwintering sites in the commercial onion, Allium cepa L., cropping system were investigated early in the spring before onion seedling emergence and again late in th...

The question whether lipid based - especially triglyceride based - depot systems can undergo biodegradation is despite many in vivo studies still unanswered. In this paper we studied biodegradation processes in vitro by incubating these lipid based systems in buffer media containing lipases. The main degradation product the free fatty acids (FFA) were isolated from the drawn samples and after d...
