The effects of volatiles from tea plants induced by exogenous methyl jasmonate (MJA) spraying or MJA-exposure on host-selection behavior of the parasitoid Apanteles sp. and the geometrid Ectropis obliqua as well as the percentage of E. obliqua caterpillars parasitized by Apanteles sp. under field condition were studied. Tea volatile organic compounds (VOC) induced by exogenous MJA-spraying or MJA-exposure exhibited a significant increase of attractiveness to female adults of Apanteles sp., but not to female adults of E. obliqua; and also significantly increased the percentage of E. obliqua caterpillars parasitized by Apantele sp in field condition.
