Rare plant alarm volatile (E)-4,8-Dimethyl-1,3,7-nonatriene (E-DMNT) available from Pherobank BV

The unusual acyclic C11 homoterpene (E)-4,8-Dimethyl-1,3,7-nonatriene is emitted by many plants as a response to herbivore attack (see figures 1 and 2). Also this volatile is described as being an attractant for several insect species, among which Cydia pomonella (males and females), Neoseiulus womersleyi, Myllocerinus aurolineatus (Tea weevil), Phytoseiulus persimilis (Predatory mites), Orseolia oryzivora (African rice gall midge), Cotesia marginiventris and Microplitis croceipes.

The Z-isomer (Z)-4,8-Dimethyl-1,3,7-nonatriene (Z-DMNT) is available as well.
