(1) Terpene hydrocarbon fraction (H_T) of essential oil (E_T) from a trunk of Pinus desiflora masked (blocked/diminished) response by female cerambycid beetle, Monchamus alternatus to oxygenated terpene fraction (O_T) of E_T, with no instrict repellency.(2) H_F fraction from foliage also masked the attractiveness of o_T, while O_F from foliage exhibited repellent activity.(3) Crude masking substances X_T and X_F, respectively, were separated from residues (R_T, R_F) obtained by reduced-pressure distilllations of E_T and E_F, using TLC and GC.(4) The crude X_T and X_F stopped the response by the female, and made her stand still. X_T and X_F were found to be busking substances.(5) The substances were unstable ; sixty % of X_F in n-pentane changed into other compounds after 10 days.(6) X_F was isolated from R_F by reversed phase HPLC.(7) X_T and X_F will be isolated, biossayd, and chemically identified. Then, masking mechanism will be investigated.

（1）从雌性cerambycid甲壳虫，Monchamus替代品对E_T的含氧萜烯馏分（O_T）的E_T的Monchamus替代甲壳虫的反应（terpene烃（H_T））的精油（E_T）的E_T的甲状化（E_T）。 （2）叶子的h_f分数也掩盖了O_T的吸引力，而叶子的O_F分别表现出驱动性活动。（3）粗掩蔽物质X_T和X_F分离出与残留物（R_T，R_F）分离的，该物质通过减少的压力蒸馏器获得E_T和E_F，使用TLC和GC。（4）原油X_T和X_F停止了女性的响应，并使她的站立保持不变。 X_T和X_F被发现是繁忙的物质。（5）物质不稳定； N-Pentane中的X_F的60％在10天后变为其他化合物。（6）通过反向相HPLC从R_F分离X_F。（7）X_T和X_F将被分离，生物覆盖，化学识别。然后，将研究掩盖机制。
