Abstract
We are seeking to enhance the natural defence systems of crops as an effective, sustainable method of pest control. Amongst the many strategies employed by plants is the production of volatile compounds (semiochemicals) that modify insect behaviour. In this proposal we aim to modify insect pest behaviour through production of the volatile sesquiterpene hydrocarbons germacrene-A, germacrene-D and E-beta- farnesene in the model species Arabidopsis. This will be achieved by expressing cDNAs encoding their respective terpene cyclases, which we have recently isolated, under the control of constitutive and inducible promoters. The plants will be tested for accumulation of the sesquiterpenes and for effects on the behavioural ecology of their insect pests.
