摘要
3种赤眼蜂在多种寄主卵单独或共存条件下,趋向产卵的行为反应趋势相似。各“蜂—卵”组合之间,在上卵蜂率,偏嗜指数等行为反应指标上均有明显差异。该趋势与寄生特性不尽吻合,不同蜂种对不同寄主卵有各自的偏嗜性选择。繁蜂所用中间寄主卵,对蜂种原有的寄主选择嗜好性具有驯化改造作用,赤眼蜂对寄主卵的有机溶剂抽提物有敏感的趋向行为发生,赤眼蜂对寄主的选择性行为可能与寄主卵的化学信息物质有关。
When many kinds of hosts were individually existed or coexisted, the oviposition preference of 3 species of Trichogramma was almost the same. There were significant differences, such as ten-dency rate of eggs and preference index of Trichogramma, among different groups of "Parasite -host", but the tendency was not fully the same as the parasitizing characters. Host choices were varied with the different species of Trichogramma, Intermediate hosts were used to Trichogramma re-production which could improve the original addiction of Trichogramma to its hosts. Trichogramma species were sensitive to semiochemicals of host eggs.
