Resumen:
The invasive spotted-wing drosophila, Drosophila suzukii (Matsumura), is
a major pest of soft-skinned fruits. Since its introduction into North
America and Europe, significant progress has been made in understanding
the volatile cues used by this fly during food, oviposition site, and
mate finding. Despite this progress, commercially available lures are
non-selective. Here, we tested two Hanseniaspora uvarum (Niehaus) yeast
compounds (isoamyl acetate and isobutyl acetate) and a leaf compound
beta-cyclocitral alone and in combination with a blend of four
fermentation compounds ('Fermentation lure': acetic acid, ethanol,
methionol, and acetoin) to improve D. suzukii attraction and
selectivity. In laboratory assays, males and females were attracted to
all seven individual compounds, although in electrophysiological assays,
their antennae exhibited a dose-dependent response to only four of these
compounds. In two-choice cage studies, the Fermentation lure was more
attractive to D. suzukii than water controls, whereas beta-cyclocitral
and the mixture of isoamyl acetate and isobutyl acetate were not
attractive in this larger-cage study. Moreover, adding the two-component
H. uvarum compound blend to the Fermentation lure reduced D. suzukii
attraction to the Fermentation blend. When these experiments were
repeated in blueberry, raspberry, blackberry, and cherry orchards across
several states in the United States over 2 yr, similar outcomes were
observed: beta-cyclocitral or the mixture of the H. uvarum blend did not
improve the attractiveness of the Fermentation lure or its selectivity.
This study demonstrates that cues from different sources may interfere
with each other and reduce D. suzukii attraction to otherwise attractive
odor combinations.
