| 摘 要： | 利用中间寄主柞蚕Antheraea pemyi蛹大量扩繁白蛾周氏啮小蜂Chouioia cunea Yang经多代后寄生效果下降,系由蜂种退化所致,即利用一种中间寄主导致蜂种的营养来源单一。据此设计复壮措施,即利用自然寄主回接。结果表明：回接1代,其子代蜂种的寄生率提高了27.33%-35%,雌雄比提高了32.38%-73.23%。 |
| 关 键 词： | 白蛾周氏啮小蜂 复壮 寄生率 |

| Abstract: | The breeding effect decreased after several generations in rearing Chouioia cunea Yang by using the pupa of the yellowmealworm,Antheraea pemyi.The main reason included using the same kind of host.The measure of population rejuvenation was designed: using natural host for one generation.The results showed that the parasitism rate and the female to male sex ratio raised by 27.33%~35% and 32.38%~73.23% respectively after using natural host for one generation. |
| Keywords: | Chouioia cunea Yang rejuvenation parasitism rate |
