摘要：

为了明确不同比例蚜虫饲喂对异色瓢虫产卵特性的影响，为后续瓢虫人工饲料的研究奠定理论基础。试验设计5个处理，分别是饲喂蚜虫减量100%、75%、50%、25%、0%，即A、B、C、D、E，A为全饲料饲喂对照组，E组为全蚜虫饲喂对照组。试验过程中记录各处理异色瓢虫的产卵量、孵化率、死亡率及产卵位置等指标。研究结果表明，D组与E组产卵量没有显著性差异，减量50%及以上的蚜虫饲喂处理异色瓢虫产卵量均显著低于对照组。各处理可收集卵块数量及卵粒数量极显著高于不可收集卵块及卵粒数量，A、B、C组可收集产卵量极显著低于E组；各处理异色瓢虫产卵量跟随时间的变化呈现明显的波动变化，平均4天一个峰值；B、C、D组的孵化率略高于对照组E组，但无显著性差异；雌虫的死亡率普遍高于雄虫的死亡率，死亡率由高到低分别为E组>A组>B组>C组>D组。本研究表明减量25%的蚜虫饲喂没有降低异色瓢虫的有效产卵量，减量50%以上的蚜虫饲喂显著降低了异色瓢虫有效产卵量，明确了不同比例的蚜虫减量饲喂对异色瓢虫产卵特性的影响。

Abstract:

In order to clarify the effect of different proportions of aphid feeding on the oviposition characteristics of Harmonia axyridis, and lay a theoretical foundation for the follow-up study of artificial diet of H. axyridis, five treatments were designed in this experiment, which were fed with aphid reduction of 100%, 75%, 50%, 25% and 0%, namely group A, B, C, D and E. Group A was fed with artificial diet and group E was fed with aphid. The quantity, hatching rate, mortality and location of oviposition under each treatment were recorded in this experiment. The results showed that there was no significant difference in the amount of eggs laid between group D and group E, the amount of eggs laid by ladybugs fed with aphid reduction of 50% or more was significantly lower than that of the control group. The number of collectable egg masses and egg grains in each treatment was significantly higher than that of non-collectable egg masses and egg grains, and the number of collectable eggs in group A, B and C was significantly lower than that in group E. The oviposition amount of ladybugs in each treatment fluctuated significantly with time, with an average peak of 4 days. The hatching rate of group B, C and D was slightly higher than that of group E, but there was no significant difference. The mortality rate of females was generally higher than that of males, the mortality rate from high to low was Group E>A>B>C>D. This study showed that the reduction of aphid feeding by 25% did not reduce the quantity of effective oviposition of H. axyridis, and the reduction of aphid feeding by more than 50% significantly reduced the quantity of effective oviposition of H. axyridis, thus clarifying the effects of different proportions of aphid reduction feeding on the oviposition characteristics of H. axyridis.
