(Z)-3-nonenol, (Z,Z)-3,6-nonadienol and (S,S)-(-)-epianastrephin: male produced pheromones of the Mexican fruit fly
1985
Robacker, David C. | Hart, William G.
(Z)-3-nonenol, (Z,Z)-3,6-nonadienol and (S,S)-(-)epianastrephin proved active as male-produced pheromones which elicited behavioral responses from virgin female Mexican fruit flies (Anastrepha ludens) (Diptera: Tephritidae) in laboratory bioassays. All three chemicals elicited attraction and/or locomotor arrest when tested individually. When tested together, (Z)-3-nonenol inhibited the behavioral effect of (Z,Z)-3,6-nonadienol but either of the alcohols synergized the effect of (S,S)-(-)-epianastrephin. Quantities of the pheromones per male abdomen were: (Z)-3-nonenol −100 ng; (Z,Z)-3,6-nonadienol −40 ng; and total epianastrephin (R,R and S,S enantiomers) −700 ng. Relative to the quantities in abdominal extract, males released these chemicals during sexual display in a blend containing a higher proportion of the alcohols.
