The effect of the Drosophila melanogaster female sex pheromone (Z)-4-undecenal on oviposition of the spotted wing drosophila Drosophila suzukii on blueberry, and attraction to an associated yeast, Hanseniaspora uvarum. Oviposition assays (choice tests with blueberries, and blueberries treated with (Z)-4-undecenal), wind tunnel tests (attraction to Hanseniaspora uvarum with and without and (Z)-4-undecenal), and a field trapping test (attraction to Hanseniaspora uvarum with and without and (Z)-4-undecenal).


Steps to reproduce

Mated Drosophila suzukii flies had the choice to oviposit on two blueberries, treated and untreated. Eggs laid on both berries were counted after 24 h. In a wind tunnel, upwind attraction of individual Drosophila suzukii flies to the yeast Hanseniaspora was observed and counted. In the field, the number of Drosophila suzukii flies captured in traps baited with the yeast Hanseniaspora were counted.
