Comparison of volatiles emitted by male Caribbean and Mexican fruit flies

Volatiles emitted by Anastrepha suspensa and Anastrepha ludens males were trapped and compared by GC-MS. Both species emitted previously reported nine-carbon alcohols, (Z)-3-nonenol and (Z,Z)-3,6-nonadienol, and epimeric lactones, anastrephin and epianastrephin. A third isomeric lactone, the macroli...

Description
Summary:Volatiles emitted by Anastrepha suspensa and Anastrepha ludens males were trapped and compared by GC-MS. Both species emitted previously reported nine-carbon alcohols, (Z)-3-nonenol and (Z,Z)-3,6-nonadienol, and epimeric lactones, anastrephin and epianastrephin. A third isomeric lactone, the macrolide suspensolide, which was previously known only from A. suspensa is reported here for the first time in the volatiles of A. ludens. We also report that both species released different proportions of the same three sesquiterpene hydrocarbons: alpha-farnesene, beta-bisabolene, and alpha-trans-bergamotene. The beta-bisabolene was isolated in sufficient quantity from A. suspensa volatiles to establish its absolute configuration as the (R)-(+)-enantiomer. Some plausible biosynthetic relationships of famesol to the isoprenoid lactones and sesquiterpenes identified in this study are discussed. Finally, we report that A. suspensa produces the monoterpene (Z)-beta-ocimene while A. ludens volatiles contained limonene.
