Sažetak
The olive fruit fly (Bactrocera oleae Gmel.) is one of the most damaging pests of olives worldwide, requiring use of insecticides for protection in many orchards. Research leading to effective new methods of trapping and control that are less disruptive to the environment is a goal of our research. Bactrocera oleae is known to respond behaviorally to volatile natural compounds including pheromones and semiochemicals produced by its host plant and bacterial filtrates. Laboratory bioassays for B. oleae attraction of over 130 yeast strains from among 300 that were isolated from adult B. oleae, infested olives, and potential feeding sites, suggested that 10 appeared to attract B. oleae as well or in greater abundance than did torula yeast (Candida utilis). Field assays of live yeast cultures placed into McPhail-type traps in 2015 showed that B. oleae were more highly attracted to five of them. Volatile compounds emitted by these five yeast strains were analyzed by SPME/GC/MS to identify compounds that could be responsible for B. oleae attraction included isoamyl alcohol, 2-phenethyl alcohol, 2-phenethyl acetate, isobutyl acetate, and isobutanol. The behavioral response of B. oleae adultsto these pure volatile compounds at three concentrations was tested using a two choice Y-tube olfactometer. The alcohol isoamyl alcohol appeared to be more attractive than the other compounds tested. The same compounds are currently being evaluated in a field assay. The most attractive of these compounds to olive fruit fly have potential for use as more specific baits for detection, monitoring, and control of B. oleae.
