Abstract Drosophila suzukii was a known pest of berries, grapes, and stone fruits in East Asia for
almost a century. Yet in recent years it has successfully migrated throughout the United
States, Mexico, and Europe due to globalized fruit trade. The invasive success of D. suzukii is
causing unrest for fruit growers in these regions who face severe economic loss from
infestation. An ovarian maturity study was conducted by dissecting field-collected females.
Study results show mid-Willamette Valley, Oregon D. suzukii females to be most
oviposition-ready between June and September. A trap design study was conducted to
quantify features of a successful trap for monitoring and eradication. Headspace, the volume
between the liquid bait surface and the closest entry hole, was found to be a significant
design feature. Successful trap designs, such as the Side Mesh trap used during summer 2012,
can be used to monitor field presence and population accumulation. Knowledge of D. suzukii
ovarian maturity in combination with trap catch, fruit phenology and weather patterns can
be used to predict D. suzukii activity and help time treatment before infestation. These
results contribute to an integrated pest management strategy for D. suzukii to reduce
pesticide dependence.
