Abstract:A series of new compounds was synthesized to study the effect or varying the structure of the siglure molecule on attractiveness to the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The effect of removing or adding methyl, ethyl, and ehloro groups at various positions was determined. These modifications can greatly affect the activity of the molecule. Some of the compounds were prepared to check the predictions or R. H. Wright (Nature (London) 198: 455-9 (1963) relating to his theory or molecular vibration and insect attraction. The data did not support his view that replacement of the ring methyl by ethyl or hydrogen would destroy activity. However, activity was diminished in most instances by these changes. The implication that the stereo chemical positioning of the —CH3 and —CO— group of the cyclohexene molecule is important was examined by preparing and determining the activities of hydrogenated and epoxy derivatives as well as by checking results obtained with halo compounds previously prepared. The spatial position of the aforementioned methyl and carboxyl groups was not altered appreciably in these materials. These analogs retained their attractiveness, but differences in activity of the compounds indicated that other effects of the substitutions are important.
