Volatility and attractiveness to the Mediterranean fruit fly of trimedlure and its isomers, and a comparison of its volatility with that of seven other insect attractants



Volatility and attractiveness to the Mediterranean fruit fly of trimedlure and its isomers, and a comparison of its volatility with that of seven other insect attractants



Journal of Economic Entomology 59(6): 1450-1455



A simple laboratory method, devised to determine the relative rates of evaporation of chemical insect attractants, was used to determine the relative rates of volatilization of trimedlure, its 4 isomers, and 7 other attractants. The volatilization of these materials correlated well with their persistence as attractants in the field. The volatility of the individual trimedlure isomers and their attractiveness were not necessarily related. Thus, 1 of the 4 isomers did not attract the Mediterranean fruit fly, Ceratitis capitata (Weidemann). These results indicated that the stereo-chemistry of the molecule is the important factor in attractiveness. The isomer composition of liquid commercial trimedlure during its evaporation was determined by gas chromatography. Although the composition changed, all 4 isomers persisted even after 95% of the lure had evaporated. Two of the isomers may solidify, especially during cold weather; in this form their volatilities are much less than when they are liquefied, i.e., dissolved in the liquid isomers. To overcome this tendency to solidify, materials were added to trimedlure to inhibit crystallization. Of 18 compounds tested diethyl butylmalonate was the best inhibitor, but in the field it depressed the attractiveness of the lure. Pentadecanolide, a fixative and odor enhancer used in the perfume trade, extended the period of attraction of trimedlure appreciably but not that of cue-lure or siglure.
