| 摘 要： | 以黄粉虫Tenebrio molitor L.蛹作为白蛾周氏啮小蜂Chouioia cunea Yang的人工寄主,在（28±0.5）℃条件下观察其发育历期,以不同蜂蛹比例进行接种,观察小蜂的寄生情况。结果表明,黄粉虫蛹能够满足白蛾周氏啮小蜂发育的营养需求,发育历期为17.2～22.9d,虽然成功寄生率只有75%左右,但基本可以满足常年大规模繁蜂的需要。不同接蜂比例对寄生率、出蜂蛹率和出蜂量有显著影响,蜂蛹比在2∶1以上较好。白蛾周氏啮小蜂在冷冻致死的黄粉虫蛹上也有产卵行为,但蛹内卵和幼虫量很少,它们在死亡寄主体内存活不超过72h。

| Abstract: | Reproduction of Chouioia cunea Yang using pupa of Tenebrio molitor L.as factitious host at（28±0.5） ℃ in laboratory were investigated.Developmental period of C.cunea from egg to adult was 17.2-22.9 d at 28 ℃;proportion of wasps that successfully parasitized host pupa was about 75%.Wasp to host pupa rate significantly influenced percentage of parasitism and pupae with wasp emergence and number of wasps emerged,which achieved maximum value when the ratio of wasp to pupa was 2∶1.The wasp could oviposit on host pupae frozen dead,but only few eggs and larvae of the wasp were found,and they would die within 72 h. |
