Temporal Dynamics of Host Use by Drosophila suzukii in California's San Joaquin Valley: Implications for Area-Wide Pest Management.

ABSTRACT: A major challenge to the area-wide management of Drosophila suzukii is understanding the fly's host use and temporal dynamics, which may dictate local movement patterns. We determined D. suzukii's seasonal host use in California's San Joaquin Valley by sampling common crop and non-crop fruits in a temporal sequence of fruit ripening. We then evaluated the suitability of selected fruits as hosts. Drosophila suzukii emerged from both intact and damaged cherries during the cooler, early season period. Fly density remained low through the hot spring-summer period and re-surged as temperatures lowered in fall when the fly did not cause damage to intact peach, nectarine, plum, pear, grape, pomegranate, apple, persimmon and citrus (in order of ripening) but did emerge from the damaged fruits of t
