Abstract:
The spotted‐wing drosophila ( SWD ), D rosophila suzukii ( D iptera: D rosophilidae), originally distributed across a few A sian countries including S outh K orea, has invaded N orth A merica and E urope but is absent from A ustralia. In order to export the S outh K orean grape cultivar C ampbell E arly to A ustralia, its potential to serve as an oviposition and development medium for SWD must first be determined. In this study, we determined the oviposition and development potential of SWD on C ampbell E arly, after elucidating the SWD life cycle and establishing an artificial diet‐based mass‐culturing system. An investigation of the life cycle under five temperature regimes (16, 19, 22, 25 and 28° C ) showed that the durations of the egg, larval and adult stages were shortened when temperature was increased from 16, 19, 22, 25 and 28° C , but pupal duration was shortest at 25° C and extended again at 28° C . A test of oviposition and development potential of SWD on C ampbell E arly grape clusters showed oviposition of 30.8 ± 6.8 eggs per cluster of injured grapes and 157.7 ± 16.2 eggs on a culture dish of artificial diet. However, in a similar experiment using uninjured grape clusters, only a single egg was deposited on the grape skin, which soon dried. In light of these results, newly harvested grapes left at vineyards during daily harvests are unlikely to serve as an oviposition and development medium for SWD , as long as the grapes remain uninjured.
