The spotted-wing drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), originally distributed across a few Asian countries, including South Korea, has invaded North America and Europe, but is absent from Australia. In order to export the South Korean grape cultivar Campbell Early to Australia, its potential to serve as oviposition and development medium for SWD must first be determined. In this study, we determined the oviposition and development potential of SWD on Campbell Early, 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 shorten 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 Campbell Early 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.

'Green King', a new green tetraploid table grape cultivar with large berries, was originated from a cross between ‘Tensyu’ and ‘Beni Fuji’ grape cultivar in 2000. The cultivar was preliminarily selected among the elite breeding lines for its superior growth characteristics in 2005. After an extensive three-year evaluation of fruit and tree characteristics as 'GWG2002-02', 'Green King' was finally selected in 2008. Under Chuncheon’s ecological conditions, the average harvest date for 'Green King' is 6 September, and the number of days from flowering to harvest is 88 days. Hence, it is 12 days shorter than 'Rosario Bianco'. The average weight of a cluster in 'Green King' is 379.6 g, and its yield is 1,852 kg/10a. It has larger fruit size and higher fruit productivity than ‘Rosario Bianco’ (Registration No. 3560).
