Abstract
Twenty-six ester analogs of 1,1-dimethylethyl cis -4-chloro- trans -2-methyl-cyclohexanecarboxylate (TML-C), the most attractive isomer in trimedlure (1,1-dimethyl-ethyl 4(and S)-chloro- trans -2-methylcyclohexanecarboxylate), were evaluated for initial and persistent attraction of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), along with a standard commercial trimedlure blend of isomersand TML-C. Five of the esters were as attractive as TML and TML-C in the initial phase of the test and were as effective as TML-C in the persistent phase of the test. Three ester analogs of 1,1-dimethylethyl trans -4-chloro- trans -2-methylcyclohexanecarboxylate (TML-B2) that were more volatile than TMLB2 the least attractive and least volatile isomer in trimedlure, showed levels of attraction similar to that of TML-B2. These results support the hypothesis that the lesser attraction of C. capitata to TML-B2 is caused by molecular configuration rather than lower volatility.
