The present invention provides compounds and compositions for attracting or repelling sap-sucking insects, such as whitefly, as well as methods for using such compositions.

Plant volatiles

The invention provides a method for controlling whiteflies which comprises the steps of: providing a composition comprising or consisting of R-curcumene and optionally further beta-myrcene, para-cymene, gamma-terpinene, alpha-terpinene, alpha-phellandrene zingiberene and/or 7-epi-zingiberene; and adding said composition one or more times to a plurality of crop plants. The method can be combined with the use of attractant compositions comprising beta-phellandrene, limonene and/or 2-carene, and optionally adding said composition one or more times to one or more trap plants and/or trap materials.

Plant volatiles based on R-curcumene

A new farnesene synthase was isolated from tomato. The farnesene synthase shows surprising properties with regard to the end products formed and its gene has, on a nucleotide level, low sequence identity with known farnesene synthase genes from other sources. The invention relates to isolated polynucleotides, polypeptides encoded by said polynucleotides, genetic constructs, vectors, hosts, in particular plants, harboring such polynucleotides, polypeptides and genetic constructs, and seed derived from such plants.
