| 为了明确班氏跳小蜂不同生殖方式及雌蜂密度对种群的影响，研究了班氏跳小蜂在不同雌雄比例的两性生

| 英文摘要: |
| The effects of reproductive patterns and Aenasius bambawalei female adult density on the parasitization rate and offspring sex ratio were determined in the laboratory. The results indicated that the reproductive model of A. bambawalei included bisexual reproduction and arrhenotoky. Meanwhile，the parasitization rate of A. bambawalei increased with the increase of parasitic wasp density and peaked
( 49.13 %) with 20 ∶ 1 female to male ratio. The offspring female ratio peaked with 15 ∶ 1 female to male ratio. Additionally， the parasitization rate and offspring female ratio were higer when two female A. bambawalei occurred at the same time. This study interpreted that bisexual reproduction and two female parasitic wasps occurred at the same time were more beneficial for the population development of A. bambawalei. |
