A dynamic headspace analysis was performed on the volatile components ofE802 Mazofermsteepwater, a condensed fermented corn extractive, that is highlyattractive in laboratory and fieldtests to adult Mexican fruit flies, Anastrepha ludens(Loew). Chemical characterization wasaccomplished by capillary GC and GC/MS methods. A total of 19compounds were identified, andthese were comprised of 6 alcohols, 5 esters, 3 aldehydes, 2 lactones,an alkyl furan, an acid, and atrisulfide. When E802 Mazoferm steepwater was analyzed at pH 3.9,the five most abundantcompounds in the volatiles (in descending order) were3-methyl-1-butanol (43.9%), ethyl lactate(23.7%), ethanol (15.4%), 2-methyl-1-propanol (12.8%), and ethylacetate (0.71%). At pH 8.0, thesame five compounds were again the most abundant. Except for areversal in order for the firsttwo compounds, the order was the same: ethyl lactate (37.3%),3-methyl-1-butanol (32.5%), ethanol(14.2%), 2-methyl-1-propanol (10.4%), and ethyl acetate(3.09%).Keywords: Anastrepha ludens; food bait; attractant; E802 Mazofermsteepwater; volatiles;headspace analysis; lure
