Sažetak
Since the olive fruit fly, Bactrocera oleae Gmel., was found in California (USA) in 1998, it has been detected in all olive growing areas, and is capable of causing complete yield loss when not controlled. Previous research has shown that torula yeast (Candida utilis) hydrolysate is more effective bait than spiroketal sex-pheromone or ammonium based lures. Only two of the 900 known yeast species have been evaluated for use as insect attractants. The relative attraction of other yeast species for B. oleae or other tephritids, has not been evaluated. We have isolated and identified over 300 yeast strains belonging to over 50 species from adult flies, infested olives, and potential feeding sites. Many of these yeasts were only found once or very few times while others occurred more frequently. We tested over 130 yeast species for B. oleae attraction. Of these, 15 yeast strains appear to attract B. oleae as well or in greater abundance than did torula yeast. Ten of the most attractive yeast strains were placed as live yeasts cultures in McPhail-type traps in olive orchards for 10 days, and the number of flies in each trap were counted daily. Bactrocera oleae adults were significantly more attracted to the following live yeast cultures than others: Kuraishia capsulata, Peterozyma xylosa, Candida silvicola, Lachancea thermotolerans and Candida ergatensis. Volatile compounds were identified by SPME/GC/MS, and evaluated for B. oleae attraction. Volatiles produced by attractive yeast cultures could prove useful as an IPM tool for monitoring or control of B. oleae.
