Abstract

1,4-Cycloaddition reactions between (E)-β-farnesene (the aphid alarm pheromone) and dienophiles, such as SO2 and RO·CO·C ≡ CCO·OR, gave products more stable and less volatile than the parent compound. In laboratory experiments, the numbers ofMyzus persicae (Sulz.) settling and nymphs deposited on plants were decreased by some of the reaction products. Acquisition, and thereby transmission, of the semipersistent beet yellows virus and the nonpersistent potato virus Y, was decreased.
