摘要: 研究了应用外源MJA喷雾法或暴露法处理茶树后诱导的挥发性有机化合物对单白绵绒茧蜂和茶尺蠖成虫的行为选择,以及对单白绵绒茧蜂对茶尺蠖幼虫寄生率影响的研究。结果表明,外源MJA喷雾法或暴露法处理茶树,其诱导挥发性有机化合物对单白绵绒茧蜂成虫具有很强的引诱作用,对茶尺蠖成虫引诱作用不明显,在茶园中,显著提高单白绵绒茧蜂对茶尺蠖幼虫的寄生率。

Abstract: 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.

Key words: Camellia sinensis, Methyl jasmonate, Host-selection, Apanteles sp, Ectropis obliqua
