Description
Summary:The swede midge, Contarinia nasturtii, is a serious gall-forming insect pest of most cultivated Brassicaceae such as cauliflower and cabbage. Arabidopsis thaliana, also a Brassicaceae, is a well-known model plant for which the genome is sequenced and several well-characterized mutants and transgenic genotypes are available. Previous results indicate that odours from cauliflower attract C. nasturtii. In this study the responses of C. nasturtii to volatiles from cauliflower and Arabidopsis were tested in a four-arm and a y-tube olfactometer. The results indicate that females are attracted to volatiles both from cauliflower and Arabidopsis. Males on the other hand were not attracted. This study also suggests improvements for the y-tube as well as a four-arm olfactometer setup.
