Abstract
cis-Jasmone has been discovered to be useful as a semiochemical that changes the behavior of insects and/or the physiology of plants. It has direct signalling roles with plant-feeding aphids, in attraction of aphid predators and parasitoids, and may act as an airborne signal inducing production of volatile plant semiochemicals, including the monoterpene (E)-β-ocimene, that stimulate foraging by parasitoids. It is an extremely benign compound having, to human beings, a pleasant aroma and gives a long-lasting effect after removal of the stimulus.
Claims23
A method of inducing the production of a volatile plant semiochemical comprising exposing a plant susceptible to a herbivorous insect to cis-jasmone, wherein i) the plant is exposed to air containing cis-jasmone at a concentration of about 10 to about 1000 μg per liter of air, or ii) the cis-jasmone is applied directly to plant tissue by foliar application.
A method of sending a plant stress signal to a plant susceptible to a herbivorous insect comprising exposing the plant to cis-jasmone, wherein i) the plant is exposed to air containing cis-jasmone at a concentration of about 10 to about 1000 μg per liter of air, or ii) the cis-jasmone is applied directly to plant tissue by foliar application.
A method of effecting expression of a gene in a plant susceptible to a herbivorous insect comprising exposing the plant to cis-jasmone, wherein i) the plant is exposed to air containing cis-jasmone at a concentration of about 10 to about 1000 μg per liter of air, or ii) the cis-jasmone is applied directly to plant tissue by foliar application.
