Yeasts Associated with the Olive Fruit Fly Bactrocera oleae (Rossi) (Diptera: Tephritidae) Lead to New Attractants

The olive fruit fly (Bactrocera oleae Rossi) is the primary insect pest in all olive growing regions worldwide. New Integrated Pest Management (IPM) techniques are needed for B. oleae to mitigate reliance on pesticides used for its control can result in negative environmental impacts. More effective lures for monitoring olive flies would help direct chemical applications to when and where required. The aim of this research was to find new, more effective methods for B. oleae detection and monitoring. Twelve insect- associated yeasts were selected and tested as living cultures in McPhail traps for attraction of olive flies. Certain yeasts were more attractive than others to B. oleae ; specifically, Kuraishia capsulata, Lachancea thermotolerans, Peterozyma xylosa, Scheffersomyces ergatensis and Nakazawae ernobii were more attractive than the industry- standard dried torula yeast (Cyberlindnera jadinii ; syn. Candida utilis). The attractiveness of dry, inactive (i.e. non- living) formulations of these five yeasts were also tested in the field. Inactive formulations of K. capsulata, P. xylosa, N. ernobii and L. thermotolerans were significantly more attractive to B. oleae than commercially available torula yeast. Green lacewing, Chrysoperla comanche (Stephens) (Neuroptera: Chrysopidae), adults were incidentally caught in traps baited with the live yeast cultures. This is the first field study that compares olive fly attraction to yeast species other than torula yeast. Commercialization of yeasts that are more attractive than the torula standard would improve monitoring and associated control of the olive fruit fly.
