摘　　要：对椰心叶甲啮小蜂的复眼和触角分别用水溶性黑色素和液体石蜡处理以探讨其视觉、嗅觉在其寄主接受行为过程中的作用;分别用椰子心叶、A4白纸、黑色薄膜3种不同方式包裹椰心叶甲蛹以探讨小蜂视觉在其寄主接受行为过程中的作用;把椰心叶甲蛹在-81℃超低温冰箱下冰冻10min后以探讨寄主蛹动对椰心叶甲啮小蜂寄生行为的影响。结果表明,椰心叶甲啮小蜂寻找寄主时嗅觉起主要作用,视觉仅起辅助作用,而寄主蛹动对该蜂接受寄主行为的影响不大。Compound eyes and antennae of parasitoid Tetrastichus brontispae Ferriere were smeared with water-soluble melanin pigment and liquid paraffin respectively to investigate the role of vision and olfaction of the parasitoid in its host acceptance behavior. Spear leaf, A4 virgin paper and black belt were used to wrap up the pupae of Brontispa longissima Gestro respectively for the purpose of investigating the effect of the parasitoid vision on its host acceptance behavior. Pupae of Brontispa longissirna Gestro were cryopreserved at -81 ℃ for 10 minutes to explore the role of motion of host pupae in host acceptance behavior of the parasitoidl The results showed that the olfaetion of the parasitoid played a main role when the parasitoid searched its host, and that the vision of the parasitoid just played an auxiliary role, whereas the motion of pupae had little influence on acceptance of the parasitoid.
