摘要: 目的 研究保幼激素和蜕皮激素对德国小蠊聚集信息素生物合成的影响,为制定德国小蠊的防制措施提供科学依据。方法 提取德国小蠊聚集信息素,用气相色谱检测各组分的相对含量。结果 德国小蠊在5龄前期摘除咽侧体,聚集信息素的2种主要组分二甲基二十九碳烷和甲基二十九碳烷的含量分别降低了10%和21%,注射保幼激素Ⅲ,2种组分的含量分别上升了32%和24%,而在5龄后期影响不明显;德国小蠊在5龄前期摘除前胸腺和注射20-羟基蜕皮酮(20-E),影响不显著,而在5龄后期摘除前胸腺,2种组分的含量分别降低了18%和12%,注射20-E后,则分别升高了26%和36%。结论 保幼激素和蜕皮激素分别在德国小蠊5龄的前期和后期参与了聚集信息素生物合成的调控。

Abstract: Objective To study the effect of Juvenile hormone(JH) and Moulting hormone(MH) on biosynthesis of aggregation pheromone of the German cockroach, Blattella germanica(L.) to provide information for German cockroach control. Methods The aggregation pheromone was extracted from epidermis and analysed by gas chromato-graphy(GC). Results Allatectomy in the first half stage of nymph of 5th instar decreased the amount of dimethylnonacosane and methyltriacontane by 10% and 21% respectively. Injected with JHⅢ, the amount of these two compounds were increased by 32% and 24%. In the last half stage of nymph of 5th instar, after extirpating prothorax the amount of the two compounds were decreased by 18% and 12%. Injected with 20-hydroxyecdysone, the amount were increased by 26% and 36% respectively. Conclusion JH and MH regulate biosynthesis of the aggregation pheromone of the B.germanica in the first half stage and the last half stage of nymph of 5th instar respectively.
