Selection of Lactic Acid Bacteria Species and Strains for Efficient Trapping of .

(1) Monitoring of is based on the use of effective traps and baits. The current baits are insufficient to provide efficient monitoring. The use of bacteria as bio-catalyzers to produce bioactive volatiles may improve flies' attraction. Thus, we conducted this work to improve Droskidrink bait's attractiveness using lactic acid bacteria. (2) Different baits that were based on the use of Droskidrink were assessed for flies' attraction in a Droso-Trap in a vineyard. , spp., and spp. were used. The performance of the most attractive species, , inoculated into Droskidrink was assessed in laboratory tests. The responses of female flies to volatiles produced by Droskidrink with strains were recorded by electroantennography. (3) Preliminary field assessment of baits recorded as the most attractive species. Three strain groups showed adaptation to test conditions. Volatiles extracted by the headspace of baits inoculated with , elicited electroantennographic responses from fly antennae. (4) Droskidrink inoculated with is a highly attractive bait for monitoring. These findings will be useful for improving the attractiveness of commercial baits based on the utilization of LAB volatiles in a strain-dependent manner.
