112 Tiddens and Cloyd: Rose Susceptibility to Japanese Beetle Feeding laboratory experiments, the leaves of Nearly Wild were fed upon extensively (52% to 78% feeding damage) by Japanese beetle adults. Field studies need to be conducted to assess the validity that Japanese beetle adults feed less on roses grown in shade. Held and Potter (2004) determined that white and yellow rose flowers attract more Japanese beetle adults than the darker colors such as apricot, orange, pink, mauve, and red. Nearly Wild rose has a dark pink flower, which may be less preferred by Japanese beetle adults. In contrast, Cabbage rose has a history of being favored by Japanese beetles in the Crasberg Rose Garden (T. Tiddens, personal observation). Plantings of Cabbage rose are located in full sun for approxi- mately 8 hr per day, and the flowers are predominantly white with slight pink coloration, which supports the findings of Held and Potter (2004). Additionally, Cabbage rose does not flower continuously; its peak flowering period coincides with peak adult Japanese beetle emergence at the Chicago Botanic Garden, thus increasing susceptibility to adult beetle feeding, which leads to this rose suffering more damage. Studies have also shown that leaves that have been fed upon by Japanese beetle adults produce induced volatile compounds that are attractive to additional adult Japanese beetles (Loughrin et al. 1995). For Cabbage rose, the combination of flower color, flowering time, and beetle aggregation may explain why this rose is so susceptible to Japanese beetle adult feeding in the Crasberg Rose Garden. Additional factors not tested in this study such as rose height, fragrance, flower size, petal count, and number of blooms may also affect rose susceptibility to Japanese beetle adults (Held and Potter 2004). In conclusion, the five rose genotypes evaluated were all susceptible to adult Japanese beetle leaf feeding. Results from the no-choice and multiple-choice experiments indicate that these rose genotypes may not be suitable selections for the Crasberg Rose Garden and Chicagoland area, and possibly other areas of Illinois. Although all were substantially fed upon in the no-choice and multiple-choice experiments, there was variation in susceptibility, suggesting they may harbor some level of resistance or tolerance. In landscape settings, a mild level of resistance or tolerance could be magnified by appropriate placement or grouping to reduce susceptibility to adult Japanese beetle feeding.
